(Definition of linear transforms, basic geometric transforms, homogeneous coordinates, transform hierarchies, perspective projection)
(Texture coordinate space, bilinear/trilinear interpolation, how aliasing arises during texture sampling, pre-filtering as an anti-aliasing technique)
(Z-buffer algorithm, image compositing, end-to-end 3D graphics pipeline as implemented by modern GPUs)
(Properties of surfaces (manifold, normal, curvature), implicit vs. explicit representations, basic representations such as triangle meshes, bezier curves and patches)
(Half-edge mesh structures, mesh operations such as tessellation and simplification)
(Closest point, ray-triangle intersection, ray-mesh intersection, the relationship between rasterization and ray tracing)
(Acceleration structures such as bounding volume hierarchies, K-D trees, uniform grids)
