I've just put up the initial code bomb at http://common-lisp.net/project/ply/src/ply in the hopes that I might gain some coding critique by airing my code in public. I hope to make ply a simple polygon mesh editor but the current code checked is just the beginning skeleton.
Ply's currently capabilities are: * Importing triangle-based meshes from Alias OBJ files (no quads). Materials, Group names, etc are currently ignored. * View Camera using Mirai style mouse buttons: Middle Mouse Button: start camera orbit mode 'q': toggle between track and orbit mode * Ortho and Perspective views ('o' key) * TAB toggles between smooth and flat shading * 'w' toggles wireframe visibility * basic lighting * primitive ray based object selection with AA bounding boxes
and the magic command to start it all: (ply:start "/path/to/some/file.obj")
Here's to more GL apps for Lisp.
