A method is described for texturing surfaces using decals, images placed on the surface using local parameterizations. Decal pa- rameterizations are generated with a novel O(N log N) discrete approximation to the exponential map which requires only a sin- gle additional step in Dijkstra's graph-distance algorithm. De- cals are dynamically composited in an interface that addresses many limitations of previous work. Tools for image process- ing, deformation/feature-matching, and vector graphics are imple- mented using direct surface interaction. Exponential map decals can contain holes and can also be combined with conformal pa- rameterization to reduce distortion. The exponential map approx- imation can be computed on any point set, including meshes and sampled implicit surfaces, and is relatively stable under resampling. The decals stick to the surface as it is interactively deformed, allow- ing the texture to be preserved even if the surface changes topology. These properties make exponential map decals a suitable approach for texturing animated implicit surfaces. |
