GL Tools Patches With Structure Inputs Would it be possible to modify the GL Tools patches that accept structure inputs (Point Structure, Line Structure etc.) so that they can work with 4-component inputs for each point, as well as the current 3-component XYZ arrays? It's a slightly obscure request, I know, but there's a reason: The OpenCL patch can't deal with or output float3s, ie structures of 3-component arrays, so you can't, for example, plug an OpenCL kernel outputting a structure into a Point Structure patch. I guess the 4th value could just be ignored. a|x

The problem isn't GLTools not accepting 4-component inputs (*), but that, as of Snow Leopard, structures can be represented internally in a new format (same issue as http://kineme.net/Discussion/DevelopingCompositions/MeshComponentKinemeG...).
The next release of GLTools will include support for float4 structures output from the OpenCL patch.
(*) It currently just ignores elements > 3, except for
GL Point StructureandGL Cube Structure, which interpret elements 4,5,6,7 as RGBA.Thanks for getting back to me smokris. I hadn't realised it was to do with the structure format. So does that mean that the next GL Tools release will be able to make use of the new faster C-backed arrays cwright was talking about? That would be cool...

Make use of them, yes.
"Faster", not sure yet. :^]
I see. It would be a shame if you didn't get any find of speed-bump out of it.
