Got all that? Here’s a cheat sheet for easy reference: In Unity, there are two primary rendering components: The Mesh Filter, which stores the mesh data of a model, and the Mesh Renderer, which combines the mesh data with materials to render the object in the scene. Finally, a UV Map maps a material to an object, specifying how textures wrap around the shape. So a mesh’s data also includes its normals, which are vectors that determine which way a particular triangle is facing, and thus how light bounces off of it. The invisible lines that connect these vertices form triangles, which define the basic shape of the object.īut in addition to the shape, the engine needs to know how to draw the surface of the object. A mesh is like a net of points, or vertices. The shape of a 3D object is defined by its mesh. Time to start with the basic vocabulary of 3D rendering.
