WebMentioning: 20 - Abstract-Compact representation of geometry using a suitable procedural or mathematical model and a ray-tracing mode of rendering fit the programmable … WebAn explicit surface representation is often necessary, since intersection tests used in ray tracing algorithms are much more efficient on explicit surfaces than on implicit ones. Once the fluxes have been found and the velocity field v ( x → ) is generated, an implicit representation can be used again to move the surface.
