Abstract
A graphics pipeline () for rendering graphics receives texture data () and vertex data (). The texture data () define rectangular texture maps (), which are axis-aligned in texture space. The vertex data () describe output quadrilaterals () in screen space. A rasterizer () rasterizes the input rectangle () by determining which texels are inside the input rectangle (). A mapper () maps the texels inside the input rectangle () onto the output quadrilaterals (). The mapping is performed by calculating screen space output coordinates from the texture space grid coordinates of the texels. For the calculation an equation is used comprising at least one linear combination of the texture space grid coordinates of the texels inside the input rectangles () and at least one product of real powers of the texture space grid coordinates of the texels inside the input rectangles ().
