For shapes of type point, disc, rectangle, sphere, box, cylinder and cone, the points are exported using the respective native Arnold nodes.

For example, Arnold has a points node, whose mode can be either disk, sphere, quad. If the ICE shape is Points, we export a points node in disk mode, etc.

Any ICE attribute can be read in the rendertree with the standard attribute shaders.

The following is a table showing how each ICE shape is translated into Arnold.


Pointpoints (mode “disk”)
Rectanglepolymesh, one quad per point
Boxpolymesh, 6 quad per point
Spherepoints (mode “sphere”)

The Segment, Capsule, and Blob shapes are not supported. SItoA skips them and they are not translated into the Arnold scene source.
