Displacement Mapping
This paper describes displacement mapping technique that is used in 3D graphics to add detail on the object’s surface. There are various approaches for implementing it that suit different usages. Most common approaches are explained and shortcomings for each are listed. An adaptive view dependant tessellation algorithm is looked at more closely and some hardware related issues are also discusse...
متن کاملDisplacement Mapping
Displacement mapping is a powerful technique for adding detail to three dimensional objects and scenes. While bump mapping gives the appearance of increased surface complexity, displacement mapping actually adds surface complexity resulting in correct silhouettes and no parallax errors. This paper presents the background to displacement mapping, current hardware implementations and how to use t...
متن کاملFeature-based Displacement Mapping
Displacement mapping was originally created as a rendering tool to provide small-scale modulation of an underlying smooth surface. However, it has now emerged as a sculpting tool, to the extent that complex geometry can effectively be added to a scene at rendering time. The attendant complexity of displacement maps is placing increased demands on rendering systems, from quality, performance, an...
متن کاملInverse Displacement Mapping
Inverse displacement mapping is a variant of displacement mapping which does not actually perturb the geometry of the surface being mapped. It is thus a true texture mapping technique which can be applied during rendering without breaking viewing pipeline discipline. The method works by first projecting probing rays into texture space and solving for a ray-texture intersection there. Shadows ca...
متن کاملPer-Pixel Displacement Mapping with Distance Functions
In this chapter, we present distance mapping, a technique for adding small-scale displacement mapping to objects in a pixel shader. We treat displacement mapping as a ray-tracing problem, beginning with texture coordinates on the base surface and calculating texture coordinates where the viewing ray intersects the displaced surface. For this purpose, we precompute a three-dimensional distance m...
