I created first person engine based on DOOMs vector calculation - example in picture. I want to find someone who made it too to exchange experiences. I have implemented optimization to not render hidden objects, collisions and "billboard" objects (allways face to player) representating enemy player (they have own direction vector with 8 different textures).
I am disappointed because of C2 speed. But maybe someone discover better (faster) solution.
I wanted to upload Node-Webkit example but DEMO not allow it and export to HTML fail because of minification. C2 v190 is broken and even when I have installed java 8, minification failed. Older C2 versions have no problems. So only picture is attached.
PM me if you want.
