Radiosity Settings

Contains controls that let you limit the number of shots to be used in the solution and to control the resolution of shadow boundaries in the final image. Accuracy of shadow boundaries is controlled with the Maximum Element Subdivisions value.

Limit Number of Shots

If on, limits the maximum number of shots used in the solution. If off, the number of shots is controlled solely by the Min(imum) Illumination Threshold value.

Min(imum) Illumination Threshold

Stops the process when the amount of unshot light energy, divided by the initial light energy, is less than or equal to the specified value.

Maximum Samples per Shot

Sets the number of samples that are taken on a source patch of the maximum size. Fewer samples are taken with smaller patches, but at least one sample is taken regardless of how small the patch is.

Maximum Patch Area

Sets the maximum area (in master units) of patches.

Selecting File > Reset Default Areas in the Radiosity dialog box resets the Maximum Patch Area and Maximum Element Area to a reasonable default based on the current size of the design. Alternatively, you can use the key-in, radiosity resetareas.

Maximum Element Area

Sets the maximum area (in master units) of elements.

Maximum Element Subdivisions

Controls the resolution of shadow boundaries by limiting the number of times an element can be further subdivided along a shadow boundary while the solution is being computed. A value of 1 allows an element to be split into four smaller elements; a value of 2 allows an object to be split into up to 16 smaller elements; and so on.

Subdivision Contrast Threshold

Specifies the relative contrast used to detect a shadow boundary.

Use Uniform SmartSolid Meshing

If on, all surfaces are meshed into triangles that have approximately the Patch Area specified.
