3D Modeling

With a 3D modeling software like Blender, artists model the shape of a 3D object, rig it so that it can be animated, animate it to move in a particular way, and texture it to give it color and shading. An example of this is shown below. Unity has a quick n' dirty implementation of a 3D modeler called ProBuilder

The reason why we use triangles to represent 3D graphics is because no matter where (in 3D space) you put the 3 points of a triangle, it is always 2D.

  • With 4 points, we can make more complex objects, such as a pyramid, which would be more mathematically complex and require higher processing power just to figure out the pixels on the surface.
