GLSL Vertex Displacment
-
Is there a way to displace vertices with the GLSL actor as is normally possible with a Vertex Shader? How do we send in some shape or mesh etc. to the shader actor? All that seems available is the rectangle the fragment shader renders to. I can move the four corner vertices of that rect at least, left and right but not in the Z plane. Is this a limit of the GLSL actor in Isadora? Would love to have full range of vertex shader in Isadora. Thanks!
