Another Look at Graftels
نویسنده
چکیده
We present a hybrid object-image algorithm for the placement of graftels in a scene. Our algorithm addresses the problem of frameto-frame coherency while maintaining image-space constraints. Graftels are attached to objects in the scene. Each graftel has a behavior function that determines its size and orientation based on the current view direction and image-space size. The placement of the graftels and the behavior functions are optimized to meet 2D image design constraints for a given set of views and image sizes. These constraints may be generated automatically using information such as the surface normal and object color, or constructed interactively.
