Geometric Implicit Decals

Thesis Geometric Implicit Decals

Adding detail to implicit surfaces is difficult due to a lack of surface parameterisation, which significantly limits their current applications. This thesis proposes a recent technique of adding small scale features to implicit surfaces through calculating a surface‘s local parameterisation using implicit decals - particle like objects scattered on the surface. The parameterisation is used to perform a geometric operation on the implicit surface, effectively refining it locally. The research is focused on applying details with use of texture maps, however different methods of local modification are also discussed.
