Warren's script is not quite right. The value -0.902 is not correct.Apparently, my picture, with a stick peptide casting a shadow on the inner surface of a deep crevice, is particularly demanding.
I have done the vector calculations. See the attached excel worksheet for light vectors for any desired stereo angle.
I am using the script below. It produces perfect shadows and reflections. turn y, 3 set light=[-0.43709,-0.34800,-0.82937] ray 1120,818 png image.l.png turn y, -6 set light=[-0.34800,-0.34800,-0.87051] ray 1120,818 png image.r.png Anthony At 05:10 AM 24/04/2003, Warren L. DeLano wrote:
In the script I just posted, I used unit vectors to specify the light direction and simply rotated that vector by 6 degrees. The first vector is merely [-0.4,-0.4,-1.0] normalized. The second is that same vector rotated 6 degrees about the Y axis. I then loaded the output into Illustrator and was able to view both cross-eye and wall-eye stereo pairs with clean shadows. > > Try using this sequence to create your stereo pair: > > set light=[-0.348,-0.348,-0.870] > ray > png image1.png > turn y,6 > set light=[-0.437,-0.348,-0.902] > ray > png image2.png > turn y,-6 > > Cheers, > Warren
