In Topic: Shape interpolation?

21 June 2016 - 01:50 PM

I was doing some research on an unrelated topic and happened to come across this. I haven't had a closer look at it, so it may be something trivial, but the exe does do 3D morphing between similar objects with identical vertex counts loaded from obj files, and it purportedly comes with source and an article included. The project is from 1998, although that needn't necessarily be anything to think ill about. It was the year Half-Life was released, after all  :ph34r: .

From the docs:
"For this technique to work, the two models you are morphing between must have identical vertex counts, and the vertices must correspond to each other."

Thanks, but my main issue is that I need to first establish a correspondence between two different sets of vertices. After that, everything becomes simple.

Sorry, this isn't a visual effect, so I can't use any hacks. It's a general application of mesh processing. It has to be a real morph.

I'm trying to morph two humanoid figures, so they do share similar features. I was thinking about projecting both meshes to an unit sphere, but I'm not sure how to match up vertices where the triangles overlap (caused by cavities around the nose, mouth, ears, fingers, etc..). Overlapping triangles would give multiple vertex matches.

Is it really necessary to map each mesh to a domain where triangles don't overlap?

Thanks, I think spherical parameterization might help here. But I need to research it a bit more. Might have problems with overlapping faces. I think if the points get smoothed out, the similarities between the two meshes will get lost.

If I have to smooth out the points, I would also like to preserve symmetry as well. Is it possible to pin two points (say the poles) to preserve symmetry, or at least pin one point to maintain a point of reference?

OpenGL has no audio capabilities.  You need a 3rd party library to handle sounds.

In Topic: Vulkan is Next-Gen OpenGL

What about the end user who never updates their graphics driver?
Will my program fail to run if no Vulcan driver found?
