Planes are flat surfaces that extent infinitely in two directions. In Direct3D, a face is a triangular area on a plane. A vertex is a point used to describe the corners of a face. Describing 3D Shapes You can describe 3D shapes with a mesh, usually built in a third party tool and stored in an X file. A mesh is made up of a series of faces.
Normals are vectors often used to describe the colors of the faces in a mesh.
You control a mesh with the IDirect3DRMMesh or IDirect3DRMMeshBuilder interface. The IDirect3DRMMeshBuilder interface is the easier to use, but it is slower. The act of moving a 3D space in Direct3D is called a translation . If you change the size of a 3D object, then you are scaling it. To Turn an object in Direct3D you rotate it.
