Verlets + vertex_attr_matrix

January 21, 2009 | 10:57 pm

Trying to decipher the Verlets patch, Just can’t find an example of how to change an attribute on a per vertex basis (I guess the vertex_attr_matrix should be used?).

For example having a jit.noise matrix control the size of the points on a per point basis.

check the rutt etra thread. my patch has a vertex attribute shader that does something similar… youd have to have a shader that edits the gl_pointsize parameter, (I think thats it – something similar). Im fairly certain thats what you’d have to do.
