Here is the call graph for this function:| def rfm2.vp.geo.sphere.Sphere.is_static | ( | self | ) |
Tells the vp code if the geometry is static or deforming, like a spot light frustum for example
| def rfm2.vp.geo.sphere.Sphere.uv_buffer | ( | self | ) |
Return a list of array coordinates for the shape. They should be ordered exactly like the vertex buffer points and have the same size as the vxt buffer. The default implementation returns a zero-filled list the same size as the vtx buffer to keep the uv buffer aligned with the vtx buffer.
| def rfm2.vp.geo.sphere.Sphere.vtx_buffer | ( | self | ) |
Return a list of vertices (list) in local space.
a 4x4 sphere looks like so:
0 1 2 3 - 0
4 5 6 7 - 4
8 9 10 11 - 8
12 13 14 15 - 12
i.e., we repeat the first an last vertex in each column so they may have
different uv coords. The first vertex has u=0.0 and the repeated first
vertex has u=1.0.
The top and bottom rows are the poles and all vertice have the same position.
| def rfm2.vp.geo.sphere.Sphere.vtx_buffer_count | ( | self | ) |
Return the number of vertices in this buffer.
