PSP developer Merick is announcing via the QJ.Net Forums the release of the Lua Wavefront 3d model viewer. As the application's name implies, it's a PSP-based 3d model viewer, and is scripted to work with cool's Lua Player Mod 4 application. As Merick explained in the thread:

I've been trying to work out how to load 3d models in Wavefront .obj format. I've gotten to the point where I can use the vertex data in the file to build a viewable model, but some of the faces don't get drawn, and some get drawn where there shouldn't be anything. Also, I think I've figured out how to put in the normals, but I can't really tell.

With what I have so far, I've put together a simple model viewer. Use the d-pad and shoulder buttons to rotate the model, and the square and cross buttons to zoom in and out.

More information - and the archive's subsequent developer discussions - are available in Merick's thread over at the QJ.Net Forums. We advise those interested in learning more about this Lua coding project to head over there. Enjoy the download.
