Appending Shapes to a TriangleBuffer?

I have program generating 3D trees. I'm using the OgreProcedural to draw my 3D representation of the tree. Trunk and branches are drawing fine. I extrude a circular shape per branch and append the trianglebuffer to a manual object. So, in the end, I have a manualobject with all branches represented as a single submesh.

So, now for the leaves. I want to represent the leaves as a quad to start, but would like to use different shapes (including custom) later. To start simply, if I do:

Procedural::Shape s = Procedural::RectangleShape().setHeight(0.5f).setWidth(0.5f).realizeShape();

how do I get a trianglebuffer from this and set position? I basically want to realize the rectangle and set UV texture coordinates on BOTH sides. Is there a way to do this? I'm hoping I can find a way to do this, and then have a loop with varied position and rotation to add replicates of the leaves around the tree. In the end, I think if all the leaves could be added in my manualobject as a one new submesh (as leaves will have a different material) it's work out well.

Any help or hints would be great. I can do this manually drawing, but it would be nice to continue to use ogreprocedural as I'm using it for the rest of the generation. Thanks!

Hi,

You can use the triangulator, once for each side. (http://docs.ogreprocedural.org/classProcedural_1_1Triangulator.html)

If you always use the same shape for each leaf, maybe caching the result of triangulator to a temporary trianglebuffer, then copying this trianglebuffer to the destination would probably give better performance.

Perfect. Thanks mikachu!
