A fast implementation of a raycaster. You can move forward by pressing the mouse button. This version also provides a camera roll and height, ceil and floor tiles. To boost up the code, I??™m using a lookup table for sin, cos, tan and massive bitshifting. The code is accordingly unreadable. What I??™m really missing is a typed Array with simple bytes to write faster code, just reading RGB values. I have the feeling, that the getPixel method is too slow. This causes the small stage (240x160px). |
