3D Modeling of Internal Combustion Engines

3D modeling of vehicle parts such as the engine requires knowledge of the major components, functions, and engine classification. Internal combustion engines have many components and these can vary according to the engine classification.

Therefore, to effectively start modeling engines it is a good idea to start off by studying the components and the engine classification.



Start off by looking at the engine configuration and its use. Also, pay special attention to the layout of the major components, which include the cylinders, pistons, crankshafts and camshafts. Then, use this to determine the main configuration of the engine. Examples of engine configurations include the four stroke engine, two stroke engine, Wankel or pistonless rotary engine, gas turbines, and jet engines.


After you have determined your engine configuration, it is helpful to locate the major components too. For this you can use engine diagrams, mechanical drawings, photographs, digital images or still renders of existing 3d models.

A great way to cut down your 3d modeling and rendering time and costs is to get a stock 3d model of an engine that has the same classification (configuration and similar components) as the engine you are looking to model or use.

When modeling engines, it is important to note that for internal combustion engines, the shape of the combined engine block and the crankcase greatly influences the location of the components. Therefore, the location of the major components of the engine and their shape can help you search for and identify the type of engine you are looking for.



For example, when 3d modeling a four-stroke engine, first identify the location and type of crankshaft, connecting rod, camshafts, and the valves. Then, identify the other components including the piston, crank pin, and cylinders. However, if you are modeling or looking for a two-stroke engine, look for an exhaust outlet and fuel inlet instead of looking for the valves.


To add detail to your engine, add the auxiliary systems such as cooling, lubricating, engine control, and exhaust systems. For example, when creating a 3d model of a rocket engine its cooling system will need additional detail and research on your end because rocket engines use fuel to cool. Also, some use controlled and gradual loss of their engine walls to cool.


When you know how your engine is classified and its major components you will be able to quickly identify and successfully start modeling 3d models of the engine that you need.

Renewable Energy and Ecological Green 3D Models

Renewable or alternative energy 3d models are used to represent the technologies and infrastructures that aid in generating energy from Earth's natural resources. Renewable energy is sometimes called green because it can be replenished naturally.

There is a wide variety of renewable energy 3d models that are used to represent the various forms of renewable energy from Earth, which include electricity and heat generated from solar, wind, ocean, hydropower, biomass, geothermal resources, and biofuels and hydrogen derived from the Earth's renewable resources. Today, the majority of renewable energy technologies are powered by the sun.


Renewable energy involves sunlight, wind, tides and geothermal heat that result from the Earth's atmosphere system dissipating energy around the globe in the form of ocean and wind currents and solar energy.


Each form of renewable energy 3d models have their own unique characteristics which influence how and where they are used. Below are some examples of renewable energy 3d models and their uses.

Wind power

Wind power 3d models mainly consists of mechanisms such as wind turnies which convert mechanical power into electricity. Wind turbines 3d models are graphical representations of turbines that exist today in the market and also turbines that are currently in development. Wind turbines typically consists of the turbine itself, the monopile foundation, transitioner with platforms and ladders, buffers and navigation lights.



Wind turbines output power greatly depends of the wind speed, so as wind speed increases, the power output increases. When several turbines are grouped together they form a wind farm. Wind farms are located in areas where winds are stronger and more constant, such as offshore and high altitude sites.

Water Power

Water power is energy stored in the water in the form of kinetic energy, temperature differentials, and salinity gradients. Water can yield much more energy than wind, sicne is about 800 times denser than air, so this means that a flowing stream of water will potentially generate 800 times more that the equivalent flowing stream of air. There are many forms of water energy including hydroelectric energy which derives electricity from the kinetic energy from flowing rivers and oceans. Ocean energy is another form of water energy and both kinetic and thermal energy is used from the ocean marine currents and the deep sea (marine current power, tidal stream power, ocean thermal energy conversion).

Solar energy

Solar energy is light and heat from the sun. Solar radiation together with other solar resources such as wind and wave power, hydroelectricity and biofuels make up most of the renewable energy available on Earth.

Solar power provides electrical generation by means of heat engines or photovoltaics. Photovoltaic (PV) cells convert the Sun's energy directly into electrical energy. Solar panel 3d models are used to design systems that can convert sunlight into active energy.

Solar 3D models are used to represent technologies that use solar energy in a wide variety of applications including space heating and cooling through solar architecture, potable water via distillation and disinfection, daylighting, hot water, thermal energy for cooking, and high temperature process heat for industrial purposes.

Solar technologies can be active or passive depending on the way they capture, convert and distribute solar energy. Active solar tecniques convert sunlight into useful outputs while passive solar techniques use the existing solar energy to increase or reduce energy consumption, such as solar architectural structures.

Solar Architecture

Advanced solar architecture and urban planning methods are used today on green building to provide light and heating. Solar Architecture methods include orientation relative to the Sun, compact proportion (a low surface area to volume ratio), selective shading (overhangs) and thermal mass.3D models are used in solar architecture to visualize an ecological or green building before the building is built. An ecological or green building typically has a roof garden with solar cell panels, solar hot water panel and light shelves at the windows. Ecological or green building 3d models are used in animations that show how a green building utilizes solar energy to meet theits power needs.

Solar Powered Vehicles

Solar Powered Vehicles are electric vehicles powered by by solar energy. The solar energy is typically obtained from solar panels on the surface (generally, the roof) of the vehicle.


3D models are used to represent the solar powered vehicles during the design, development and marketing of the solar powered vehicles. Solar powered vehicles are currently not practical transportation devices, they can be used for research purposes and extended missions to collect scientific data over long periods of time, such as volcano plume studies, North and South Poles flights, space exploration, etc.

Geothermal energy

Geothermal energy is energy obtained by tapping the heat of the Earth itself.

Geothermal power plants are used to generate power from geothermal energy and they include dry steam, flash, and binary power plants.

3D models of a geothermal plants show the technology that generates renewable energy from Earth's core including hot underground steam or water and hot underground radiogenic granite rocks.

Baseball Stadium Ballpark 3D Models

A baseball stadium or ballpark, is the place or venue where baseball games are held.

Baseball stadiums have playing field and the surrounding structure that provide spectators a variety of seating locations and other services. The ballpark can sometimes be referred as the entire structure or just the baseball playing field or ball field.

Baseball stadium 3d models are graphical representations of such structures. Each baseball stadium 3d model has a playing field and can include the surrounding structures such as the seating, roof, convenience shops, lavatories, parking, ticket stands, etc. Baseball 3d models come in a variety of widely use 3d modeling software formats including 3ds max maya lwo obj flt fbx xsi c4d dwg dfx lws and many more.


The 3d models can have different playing fields since ballparks for both amateur and professional baseball have own character when it comes to the playing field. The baseball regulations have specific standards for the diamond that is outlined by white lines. However, the rest of the field is open to the designer and hence the unique character for each baseball stadium playing field or ballfield. For amateur or little league the the ballpark refers to the playing field.



Baseball stadium 3d models are used in many industries most notably for baseball video games, baseball training and simulation, new or existing baseball stadium development, gear and memorabilia advertisements, and marketing or promotional materials.

Using a graphical representation, instead of the actual stadium, enables the graphical artist to quickly and relatively inexpensively incorporate baseball stadiums into the TV and Web advertisements, films, print proofs, video games, memorabilia, etc.

TYPES OF BALLPARKS 3D MODELS

There are several types of graphical 3d model representation of baseball stadium or ballpark. Below find some examples of baseball 3d models.


Classic Wooden Ballparks

These are the classic ballparks of the "golden age" of baseball. These were the original professional baseball stadiums and are made of wood, iron columns, and sometimes rebuilt with concrete. They had large green seats, large roofs, exposed steel, brick and stone. The spectators seats were mounted on wooden platforms. Wooden ballparks 3d models require the use of different types of wood textures. The wood textures are used during the rendering process to give the 3d model a realistic wooden look.


Multi-Purpose Stadium Ballparks


Multi purpose stadiums were built to host multiple sports and entertainment events including baseball, football, soccer, and other sports. They look like concrete donuts or cookie-cutters, tall and circular or square, and they are made mostly out of reinforced concrete. Graphical 3d model representation of multi-purpose stadiums will often include different fields for different sports and a center stage for other events. The 3d models often include the surround structures such as retractable roof and and seating.

Modern Ballparks

Baseball-only parks are built for baseball only, which gives them an initmate feel and makes them well suited for hosting large baseball games. They have seating most suited for baseball including cantilevered upper decks, seating of different colors, VIP sections, etc.

3D models of baseball seating are often customized to achieve the desired look and feel for the stadium. They are also strategically positioned throughout the stadium structure to maximize the baseball spectator experience.

How to Profit from 3D Model Creation

A single 3D model can demand thousands of dollars in profit when sold to graphics or design companies. For a 3D model to command such a high price it must be highly accurate and lifelike.
Creating polygonal models has shown to be more profitable than creating other types of 3D models such as b-spline or NURBs 3D models. This being said, many buyers of 3D models take into account that NURBs models can be transitioned into polygonal models, but it is not possible to create a NURB model from a polygonal 3D model.

There are high market values for models that are lifelike – whether they are human models, organ models or models of household items or furniture. These 3D models are necessary within video games and other animations.

These lifelike models can take extensive periods of time to complete and therefore it is important to focus on specific aspects of the model. For example, when making a model of a popular vehicle, create the exterior of the vehicle first, but overlook parts of the vehicle that are not going to be required – such as the engine, or trunk.

In order for the artist to reach high earnings levels they must have an eye for detail and the know-how, and skill to create these highly specialized 3D models. Detail and versatility are the keys to selling designs in the 3D model business. When companies purchase models for thousands of dollars, they expect the models to transition into different formats with ease. Creating models that can transition easily yields more income than a static 3D model.
For these reasons, details such as texture should be avoided as many companies employ individuals that can add on this texture. As well, when an artist adds texture to a 3D model it can make the model hard to transition into other forms.

Creation of a 3D Model Manually

In a world full of technology it is hard to imagine doing many of the things we do on a day to day basis without the use of the internet and software. The use of programs to assist in everyday life and the business world are crucial to the fast turn-around time demanded of most people’s lives. In the industry of 3D model creation, the use of high tech software is essential to keeping up with competition in the realms of movie makers, toy factories, and corporate businesses that require structure models, but what about manual model creation?

The art of model creation began before the use of PCs and started as a relaxing hobby. The use of clay, wood, metal and other more crude objects were the first materials used to create these models, and took skill and precision to create accurate to-scale recreations. Mathematics is a large part of manual model creation, and is still required in schools that train for model creation and similar professions.

Though it is not used as often (because of the use of high tech software) basic tools and mathematics are essential to creating accurate models, and is used as a test of the model creator’s true skills. Though technology is almost always faster and more precise, the art and skills involved in manual 3D model creation will always be revered as a true talent.

Creation Processes of 3D Models

Creating a 3-D model takes more than just a good idea. Though it starts with the brainstorming process, the creation of a proportionate 3D model is a compilation of detailed steps, starting with a sketch-up. One the idea has been drawn out in either graph format, simple sketch drawing format, or draft depending on the project. It is then brought to the design team (often times the creative and design team are the same department) to adapt a 3D model from the initial idea.
The next step is to put the idea in digital format with the use of manual manipulation and/or advanced software. For sign and construction companies this can mean the use of programs such as auto-cad that makes it easy to calculate proportions and relativity to the surrounding objects. For creative companies like video game programmers, this means the use of 3-D modeling methods such as Polygonal, NURBS, or Spline and Patching, all of which require the placement of lines and curves over the surface area of a frame to fabricate a life-like representation of the object, creature, or person to be modeled.

Once the finished digital design has been created, it is then sent to the production area to be completed. This can mean a factory that has a way of reading the digital information and the producing the materials, a high tech piece of machinery that uses lasers or some other form of fabrication that is programmed via the specs of the information, or the same software that is used to create the model, in some instances can be hooked up to the machine, and use a mold for the final result.

Which Modeling Method is best?

Though there are many questions as to whether or not there is one way to create a 3D model as opposed to another, the answer lies within each person’s applicable knowledge, preferred method of design, and preference to computer software. There are three main types of 3-D design that are used today, and are considered the most popular methods used by graphics design divisions in companies.

The first of these is referred to as “Polygonal modeling”, this methods uses linearly connected vertexes to create polygonal mesh that form the object. The majority of 3D models today are created using this method, as it is quick, flexible, and easy for the computer to process data input. The only disadvantage of this form of 3-D modeling is that all objects are made of tiny flat surfaces; even the curved shapes are approximated using flat surfaces.

The second method of 3-D modeling is called “NURBS” modeling. This type of modeling uses spline curves to create the appearance of life-like objects, and is put in place with the use of weighted control points. The most popular program that uses this form of design is called “Maya” and is well known commercial software. The surfaces created by NURBS are truly smooth, and though it is slightly more difficult than other methods, it creates a perfect system for organic 3-D modeling.

Splines and Patches modeling is very similar to NURBS and is also dependant on curved lines to define shape. It is between NURBS and Polygonal in its ease of use, and utilizes modeling techniques that have similarities to both. All three of these 3-D modeling methods have their advantages and disadvantages, and are dependent on the designer and their use for specific projects.

3D Models for Use in Geological Modeling

Geological modeling serves the purpose of creating 3D models of sections of the earths crust. These 3D models are unique as they can be created with different types of simulations of rocks, even the types of cells within the rocks. 3D models allow seismologists to predict certain events within the crust of the earth from shifting plates to eroding areas of the crust, or new growth within certain areas.

The grid surfaces within the programs are created with diverse polygons representing different structures and types of surfaces. These geological models are created using polygonal modeling using a meshed shell to create a surface that has been triangulated for the specific area.
3D geological modeling incorporates many other aspects of the field, including; diagenesis, structural geology, paleoclimatology and sedimentology.

Oil and Gas industries use these models to determine how the ground will react when the drills are inserted. These models are used to plan for any disturbances that may occur, as well as any weak points within the crust that could cause difficulty. If an accident were to occur, the 3D model allows the engineers to determine a plan of action for a variety of outcomes that may occur.

3D geological models are also used to complete valuable calculations for use in geostatistics. Many times, geologists are unable to calculate what is within the rock or within the crust at certain areas and therefore it is important to have software that can calculate these variables. This data is not available on regular grids and therefore must be estimated in the most effective manner.

Many popular software systems have been developed to create these 3D geologic 3D models; Roxar, Paradigm and Jewel suite are only a sample of the programs available. These powerful software systems are able to display and calculate parameters required for many professionals involved in Earth Sciences.

Types of 3D Modeling: Polygonal Modeling

Polygon modeling refers to 3D modeling which use polygons to create the shell of a 3D model. The polygons are used to create the mesh surface with the uses of vertexes in a linear pattern.
There are three common shapes created with the use of polygonal 3D modeling; triangles, quads, and elements. Triangles are formed when three sided polygons are uses, quads are formed with four sided polygons are used, and an element is created by a group of polygons connected together at a shared point.

Mesh 3D modeling uses vertexes as coordination points on the surface where three of the five surfaces of the polygon are attached to one another. Two of these vertexes that become an edge are connected by a straight line and then, each one of the polygons that are used to create the 3D modeling figure.

Polygons are the most adept form of 3D modeling for a computer to create. They can be textured or create the appearance of curved surfaces with the use of many tiny lines.
Primitives are the shapes formed within the program within the modeling environment that can be used to create a mesh. 3D modeling primitives consist of spheres, cylinders, cubes, squares, triangles and discs. Spheres are created with the use of multiple triangles to create the curved surface required for the round representation.

There are six basic operations formed in polygonal modeling. Creations refer to a new geometrical shape being formed from another mathematical object. Lofting refers to the action of generating a mesh by continuing a shape over a pattern. Extruding also copies a shape, but over the period of a line rather than a space. Revolving refers to using a shape to rotating and copying the shape around a specific point and lastly, marching cubes which can create shapes using specific algorithms.
