Quasi-Uniform Texture Parameterization for Heightfields

Planar projective texture parameterization for relief mapping and heightfields produces a distorted appearance on steep features due to variable world-space resolution in the texture map. Yet this method is widely used because it is efficient, seamless, easy to im-plement, and well-suited to algorithmically generated data. I will develop a real-time rendering method for spatially continuous deformation of a planar projective parameterization. My goal is to retain many of the practical advantages of planar projection while providing approximately uniform world-space resolution across the texture map. Motivating scenes include a stone wall and surrounding field rep-resented in a single heightfield, roots and stones depicted on a cliff wall, and visible wood grain on the sides of extruded letters in a relief-mapped store sign.
