Noob here again
How can i calculate reflecting vector in VOP SOP? I have googled it and i found sites with formulas…one of them was this (pure formula/math only):
http://ogldev.atspace.co.uk/www/tutorial19/tutorial19.html [ogldev.atspace.co.uk]
But it does not seem to work when i try to implement it in Houdini: maybe i don't understand the formula, or maybe i lay the nodes in invalid order.
I don't want to use single node, if there is such - i want to understand how its done, and then i can use the one node approach
Attached file contains a demo scene where i have tried to implement the formula. The plan, in the file, is that i can move to point and normal, and H will automatically calc a reflecting vector, and display it
