3D Isocontours Real-time Generation and Visualization of 3D Stepped Terrain Models

摘要: Isocontours (also isopleths, isolines, level sets) are commonly used to visualize real-valued data defined over a 2D plane according set of given isovalues. To support the 3D landscape metaphor for information visualization, stepped terrain can be derived by lifting and extruding isolines their particular isovalue, but typically requires triangulation resulting surface representation in preprocessing step. We present concept rendering technique triangle-based models that provide interactive, adaptive generation visualization such terrains without preprocessing. Our fully hardware-accelerated creates additional step geometry each triangle intersecting an iso-plane on-the-fly. Further, interpolation schema facilitates smooth transition between established its variant.
