Re: GLESv2 shader bug?

I have found that devices often have really awful shader compilers built in. The Galaxy S3 for instance. One game I am working on hit a problem when one shader failed to compile as it went over the 512 instruction limit. When I compiled it offline, it was 372 instructions, when I compiled it on the ...

Re: Announcement: pishadertoy

I while back I came across this site, http://forthsalon.appspot.com/ The idea of writing shaders in Forth really appealed to me, I guess I'm just weird. Use the Forth you must. I wrote a tool for Antix Game Player that compiled the Forth code into glsl shader code and blitted a full screen quad usin...
