Bug fix #2424 With a sun lamp shining exact perpendicular to a face, the result was undefined (black or full lit). Was caused by using acos() without checking the input range. Float calculus can result in small under or overflows... therefore: always use the arithb.c function saacos() !!! Found more acos() usage in rendercore (in blinn and arealight too), removed all of them. Might solve the white or black dots people were complaining about? |
