When you generate a photon or final gather visualization
map, the mapVizShape shape node is added to the scene. Adjust the
attributes of this node to change the visualization map. For more
information, see
Photon maps and
also
See the distribution of photons.
- Map File Name
-
Name of the photon or
final gather map file to be created and saved.
Photon Visibility
If the map is a photon
map, turning any of these options off hides the corresponding photon
type.
Options
- Point Size
-
This is the size of light
rays on the surface to be drawn in screen space.
- Normal Scale
-
Each photon and final
gather point has an associated normal that tells which side of a surface
it is on. Raise Normal Scale above zero to display
normals.
- Direction Scale
-
Raise Direction
Scale to display the direction from which photons arrived
on the surface.
- Search Radius Scale
-
Irradiance is estimated
from a photon map by looking up photons within a certain radius. MapViz automatically
determines a good search radius for visualization. That radius can
be scaled by Search Radius Scale.
