hey, I'm chewing on my brain last couple of days, trying to figure out how to make a 3D grid based on a Tetrahedron. I'm no good with Maths so I tried modelling it... the Tetrahedron is easy, but i can't seem to figure out how to make a grid formed with the tetrahedron... should every vertex have lines going out in 30° as far as i could calculate it's 36° don't ask me why, it seems i can put 5 together to close a shape so i cover 180° so i figured for 360° i need 10, hence an angle of 36°... anyway my brain is not got at this stuff. I'm guessing it all doable with the right script, but it will need loads of fine math. anyway any help in figuring this out is greatly appreciated! J.
