What is a vertex? Model Space and World Space View Space Projection Space End in 2D Vertices to a shape But how do we ... transform between spaces? Model -> World -> View -> Projection Space Welcome to Linear Algebra 2D Vertex, meet Matrix! Now multiply... ( 1 * x ) + ( 0 * y ) = x ( 0 * x ) + ( -1 * y ) = -y Transformations identity: scaling: rotation: Projection [1, 0, 0] [x] [x] [0, 1, 0] [y] =
