[Imstk-developers] Assimp integration

[Milef, Nicholas Boris]

I was doing some research, and apparently game engines usually don't load common formats because it takes too long. I think that we should create our own file format and have Assimp save to that format. The other benefit is that we can format it similarly to the VBO so populating the vertex data will be quick. Any thoughts on this?

Sorry, I forgot to reply to the other message. I think I used point data for the bone indices and the bone weights, but I had to bypass much of the VBO class, so technically it would only work with the right data. I'm not sure how this could be done without that file becoming very large. Is there any way we can get rid of all those function calls?

Maybe you could send a message again on the vtk developers thread to ask if a project gatekeeper could tell you how to add a third party dependency to VTK and if Assimp license works with them. If there is any issue they'll let us know and we may move on.

Do you think you could do it efficiently in VTK? If yes I'd do so, and store the vertex weights in the PointData that we could then map it to our structures.

How did you implement vertex weight in VTK in your previous work?

How should we proceed with this? It seems that there's someone interested in the VTK version. I'll need it for the Vulkan renderer to test out various things. And we'll need models that support vertex weights for both renderers.
