3D polygon to 2D texture coords

[dlangdev]

Just wondering if this is possible.

Given an obj file having vertex (v), vertex tex (vt), vertex normal(vn) and face (f). A scene is created having a node hierarchy(nh).

For static meshes non-animated, is it possible to generate a 2D texture map of the whole scene by walking the node tree and then map the quads (faces) onto a large scene texture?

Is that the way to go? should I walk the nodes, and for each node walk the faces and for each face(f), it gets mapped to a 2D texture?

Also, can I generate patches by using the faces as my given?

Thanks much.

Well you can just loop through the indices and draw the vertices in 2D on a texture using their texcoords as absolute positions in 2d space (Be sure to fmod them first incase the texcoords are outside of the range 0-1).

never thought of that.

thanks for the tip.

looks like you're taking a phd on 3d space, huh?

i'm planning on getting an ms sometime later, most probably it's going to be 3d as well.
