Hi Ralph
The idea was to use the approach of bitblit, not bitblit itself.
Say you have a method, which is called for every pixel and it depends
on a some parameters.
function renderPixel( a : Boolean )
{
if( a )
{
}
else
{
}
}
We could evaluate "a" once and compile this method to optimized SWF
bytecode at runtime.
As is said, i have absolutely no clue, if this is helpful for Flash
3D. It was just an idea ...
Cheers
Ralf.
