Hi, I've implemented the generic alpha map drawing function. There is a software version in : DrawableSurface::drawAlphaMap(...) which renders plain tiles and an overloaded OpenGL version in GraphicContext::drawAlphaMap(...) which uses Leo's code to render map smoothly
Leo, could you try to use this rendering funciton? I suggest you make a DynamicClouds class in a new set of files (DynamicClouds.h/DynamicClouds.cpp) in src/. Such class could have a single member variable that is time and a single function that is render(DrawableSurface *dest, ...) which uses PerlinNoise class to create clouds and do a double call to drawAlphaMap(...) to render it. I've seen that your second pass does some extra computation, I'm not sure exactly what it does but I think drawAlphaMap(...) has sufficient genericity in its parameters to do the job, please correct me if I'm wrong. If we do so, we can remove any cloud/perlin noise code from libgag which is cleaner. We can also hope to use the same function to render activities maps :-) In overall, what do you think? Do you agree the general idea?
