Mapas de Desplazamiento

[Jorge Javier Lara Domínguez]

Amigos, alguno de ustedes me podra ayudar a comprender como funcionan los mapas de desplazamiento para los materiales?

[Roy Hirshkowitz]

Displacement mapping changes the underlying mesh by using the texture as a height map and modifying the mesh accordingly.  Bump mapping (and Normal mapping) only alter the surface normal to give the illusion of a more complex surface.

 

Displacement mapping can be expensive to calculate, although the penalty is less for the Path Tracer.  This thread may help explain the three required properties.
