Great questions, Paolo. I hope I can give you some real answers here.

Sounds good. DesignWorkshop should prove to be a very capable and appropriate modeler for the sort of work you have in mind.

DesignWorkshop 1.7 (shipping within 30 days) will produce 3DMFs that are mostly trimesh geometry. This should result in substantial improvement over models which use only mesh geometry with QuickDraw 3D 1.5.1. We don't really know how other modelers might use trimeshes in their 3DMFs.

If the Director XTRA for QuickDraw 3D was written for QuickDraw 3D 1.0.6 then it might not support trimeshes. The trimesh geometry type was introduced in QuickDraw 3D 1.5.

DesignWorkshop does not currently store illumination values in the geometry, as was done for the LightWorks examples. For a level of effects similar to the output of the Apple QD3D Interactive Renderer, we could add this capability to DW fairly easily. For a higher level of effects, since we are already using LightWorks rendering in DW 1.6, it would be technically straightforward to integrate the more specialized LightWorks radiosity code into DW.

Let's discuss this further so we can understand your needs and look at how best to meet them.

DesignWorkshop 1.6 and 1.7 support all known QuickDraw 3D plug-in renderers, including ThinkFish.

I guess this depends on how up-to-date the QuickDraw 3D XTRA for Director is. If it is based on QuickDraw 3D 1.0.6 then it will not support plug-in renderers and may not support trimeshes. We'll look into the issues here and get back to you.

It sounds like you are doing some exciting things with 3D modeling. We are quite interested in supporting your work with our technology.
