Visualization of Complex Models Using Dynamic

We are investigating methods for simplifying complex
models for interactive visualizations using texture-based
representations. This paper presents a simplification method
which dynamically "caches" distant geometry into textures and
trades off accurate rendering of the distant geometry for
performance. Smooth transitions and continuous borders are
defined between the geometry and textures thus the
representations can be switched without sudden jumps (as is the
case with many current texturing techniques). All the
computations for the transitions can be done a priori without the
need to change the textures each frame thereafter.
Keywords: geometry, textures, morphing, visual complexity,
space partitioning, simplification, visibility culling, interactive.
