Subject: Re: [DirectPython] 3d Text



hello again,
    I can render the text now (thank you).  I can't rotate the 3d text yet
but I'm sure I'll figure the camera out.  I have access to the vertex and
vertex normals.  I am trying to export this information to a .obj
file....however I don't know how to deal with faces 'f'
 
you need the vertices:
v
vertex normals:
vn
 
and faces:
 
f 1//1 2//2 etc.
 
how do I know what points form a face?

Use the index buffer to determine faces. Direct3D meshes are made of
trianglelists (3 vertices per face), so it should not be too difficult. Here
is an example:
 
vbuffer, ibuffer = mesh.getBuffers()
i = 0
indices = ibuffer[:] #Take a temporary copy
while i < len(indices):
    print "Face ",  indices[i:i+3]
    i += 3
