Tests with the new exposure component
I was thrilled to see the exposure and occlusion components in the latest beta release of GH that David Rutten released two days ago – and I had to give them a try myself. Here’s a simple test I did combining Ted Ngai’s sun vector definition (http://www.tedngai.net/) with the exposure component. I set up a spherical cloud of vectors, and set the energy values for each ray to be a function of the dot product with the sun vector, in order to create a sort of diffuse shading effect.
