3D modellingmaya question

Examples: Inappropriate manipulations with polygonal models may produce invalid topologies. Explain what laminated faces are, when they can be produced and what needs to be done for removing them from polygonal models before you get down to texturing. Explain what Texel Density is and how it can affect visual quality of textures assigned to polygonal meshes. Explain when texel density may become irregular. Explain how its irregularity may affect visual appearance of textured 3D models. Complex 3D animated scenes must be properly captured by a virtual camera. The virtual camera can simulate commonly used filmmaking techniques. Name commonly used camera shot types and explain when they can be appropriate
