Abstract
A method carried out by a graphics processing apparatus samples a texture value of a first texture layer at an offset to a second texture layer of a surface and adjusts pixel color for a pixel of the second texture layer using the texture value such that an appearance of depth is created between the first texture layer and the second texture layer. The method may adjust the pixel color using the sampled texture value alpha component. Another method includes transforming a surface normal vector to eye space for a surface having at least first and second texture layers mapped thereto, determining an offset between the first texture layer and the second texture layer using the transformed surface normal vector, sampling a texture value of the first texture layer using the offset, and adjusting pixel color for a pixel of the second texture layer using the texture value.
