Did you know that fp3.0 supports 2 sets of vert colors, 8 uv's, and 16 textures ?

Did you know that fp3.0 supports 2 sets of vert colors, 8 uv's, and 16 textures ?

We currently don't even get half of that....imagine the things we could do.



I'm already driving a tilable texture atlas with vert colors, if we had another set of vert colors just imagine what we could do.

We have two sets of uv's , but really we only have one because one is used for lightmaps.

There have been numerous calls for having addional "mesh" attributes that can be passed per vertex to a shader.

If you're looking for a quick and easy way to legitimize a "4.0" purchase? ....this is one of those.


vertices........Returns a copy of the vertex positions or assigns a new vertex positions array.
normals...... The normals of the mesh.
tangents......The tangents of the mesh.
uv................The base texture coordinates of the mesh.
uv2..............The second texture coordinate set of the mesh, if present.
uv3..............WANT, not supported by all devices YET
uv4..............WANT, not supported by all devices YET
uv5..............WANT, not supported by all devices YET You can do more with uv's then just using them for texture ccords btw
uv6..............WANT, not supported by all devices YET You could actually use them to do lots of math and shader manipulation
uv7..............WANT, not supported by all devices YET
bounds........The bounding volume of the mesh.
colors..........Returns the vertex colors of the mesh.
colors2........WANT, vert colors are ridiculously cheap and can allow for some of the most versatile effects
triangles......An array containing all triangles in the mesh.
