Hello, I'm trying to get a cloud particle system working. As part of determining the depth of every point (to get the light that can pass through), it makes sense that the volume should be of even density. The volume is a sphere. Currently, I'm using:
vecs = numpy.random.standard_normal(size=(size,size,3)) magnitudes = numpy.sqrt((vecs*vecs).sum(axis=-1)) uvecs = vecs / magnitudes[...,numpy.newaxis] randlen = numpy.random.random((size,size)) randpoints = uvecs*randlen[...,numpy.newaxis] The particles' positions are set to randpoints. However, this creates only an even distribution of *directions *on the sphere. The particles are too closely centered around the center. What I want is a certain number of particles arranged evenly throughout the sphere. How do I do that? Thanks, Ian
