Gouraudsävytyksiä
Gouraudsävytyksiä, also known as Gouraud shading, is a method of interpolation of a scalar value (a color) on the surface of a polygon in computer graphics. It was developed by Henri Gouraud in 1971. Instead of calculating the lighting for each individual pixel, Gouraud shading calculates the lighting at the vertices of the polygon. These vertex colors are then linearly interpolated across the surface of the polygon.
The process typically involves determining the normal vector at each vertex of the polygon. Then, the lighting
Gouraud shading is computationally less expensive than per-pixel lighting methods like Phong shading. However, it can
