Abstract:
1. A method of performing cubic mapping with texturing, comprising: selecting neighboring pixels to be mapped; mapping each selected pixel to a cube face based on the magnitude of a normal vector for each face; for each of the faces to which the selected pixels are mapped, assigning a face id and defining the orientations of the texture axes of the faces in terms of the normal vectors of the cube faces, said texture axes being current texture axes; if the neighboring pixels do not have the same face id, changing the current texture axes of at least one of the faces based on assigned face ids to make the current texture axes consistent and continuous between the faces; computing an approximation to derivatives of the texture coordinates based on the current texture axes; and computing, based on continuity-adjusted derivatives, a level of detail (LOD) parameter for the texturing of said pixels.
