- Raymarching using Distance Fields Fast on Chrome and Opera. Very slow on Firefox, eval() optimization problem? To run fast on Firefox change eval(X) at the end of the script to document.write("<script>",X,"<\/script>") After optimizing the code to decrease the usage of garbage collection, the speed gain on Firefox was huge, on Chrome was already fast without this optimization, but all this speed gain on Firefox was lost after using eval() for compression :( I also created my own script compression program to compress the code. The first version, was fixed frame rate using dynamic resolution change, very easy to do using this kind of stuff, but no space left in 1K to put that, so fixed resolution. I will release the webGL version, follow my twitter at http://twitter.com/paulofalcao ;)
