Transformações Geométricas

• Points and vectors
• Coordinate systems
• Homogeneous coordinates
• Translation
• Scale
• Equivalence between transforming a point in a fixed coordinate system and transforming the coordinate system itself keeping the point fixed.
• 2D Rotations
• 3D Rotations about main axis
• 3D Rotations about arbitrary axis
• Matrix form for geoemtric transformations
• Matrix block notation
• Inverse of an arbitrary geoemtric transformation
• Composition of geometric transformations
• Drawing a snowman: push and pop matrices to preserve state
• Camera definition and “placement”
• View matrix
• Projection Matrix
• Matrices in OpenGL
• Double buffering
• Binary Space Partioning to order triangles
• Depth buffering and its precision issues
