Make Your Own Virtual 3D Car
With the availability of more powerful personal computers and less expensive (and less company) 3D modeling programs, many people are now creating their own 3D models. Some do this simply for the intellectual challenge of creating the model, while others want to use the model for rendered images or animation. One of the most often modeled objects is a virtual car. The cars can vary from a simple toon-style vehicle to something almost photo realistic. To an extent, what you end up with depends on the level of detail you are willing to spend the time creating. A good program to use for this project is Daz 3D’s Hexagon, but any 3D modeling program should be able to do it.
1. Open Hexagon. Click on the “Primitives” tab at the top and select the “Cube.” A defunct cube will be added to the scene.
2. Click on the “Faces” in the selection options at the top. Then click on “Surface Modeling” tab and choose “Fast Extrude.”
3. Now in the scene, click on the first face of the “Polygon” and extrude it forward to form the front of the car.
4. Repeat step 3 to form the trunk and roof of the car. You now have blocky car shape.
5. Select the “Vertex Modeling” and click the “Slice Tessellation” tool. Use this tool (along with the “Surface Tessellation” tool) to create a series of lines on the model corresponding to places where you want to add more definition. For example, you might want to add a cause to the hood, so you should create lines across it.
6. Change the selection mode to “Edge.” Use the tool to move the edges to produce more realistic shape for the car. You can swiftly change to the “Point” mode to move individual points, but make sure you maintain symmetry.
7. Select the “Primitives” tab and create four cylinders, placing them where the tires on the car should be. Rotate them to the correct angle. Now, under the “Surface Modeling” tab, select “Boolean” and use the function to subtract the cylinders form the car, leaving openings for tires. Create four more cylinders and place them in the openings to serve as the tires.
8. Click on the “Materials/Shading” tab on the left. Select the polygons on the model that you want for the body of the car and click on the “New Domain” icon. Rename the new domain “Body.” Then in the “Materials” section, change the color to what you want for the body. Repeat this to create the colors for all the parts of the car.
9. Select “File” and click “Export.” Name you model and save it as a Wavefront OBJ.
