Does anyone see any major problems with this task proposal? --[[User:Rdm|Rdm]] 18:05, 25 October 2011 (UTC)
: Does GLSL have a built-in random number generator?  If not, a linear gradient may be easier (and easier to verify) than a random RGB shader. --[[User:Ledrug|Ledrug]] 20:06, 25 October 2011 (UTC)
:: There is a noise() function, but apparently it's not supported very well.  However, we do not need high quality random numbers here -- modulo and arc tangent using old pixel value and coordinate values could probably be made into something adequate.  I would like to avoid a gradient, however, because we already a gradient in [[OpenGL]]. --[[User:Rdm|Rdm]] 03:17, 26 October 2011 (UTC)
