Hi, just started using megapov and have a few questions due to some
unexpected results of trying out "slope".
1. If I have "slope y", is the following correct?
normal vector < 0, -1, 0 > returns 0.0
normal vector < 1, 0, 0 > returns 0.5
normal vector < -1, 0, 0 > returns 0.5
normal vector < 0, 0, 1 > returns 0.5
normal vector < 1, 0, 1 > returns 0.5
normal vector < 1, 1, 1 > returns 0.75 (?)
2. Is there a formula for calculating the return from any particular normal
for a specified slope value?
3. Since scaling an object unevenly will modify surface normals, presumably
slope y pigments are affected by whether they are before or after such
scaling?
Many thanks.
