Hi all, I'm currently trying to implement in OpenGL image processing algorithms. I would like to successively use several shaders in order to perform several filters (Sobel Gaussian,...). I understood that to do thius I had to render to texture thanks to a FBO. I read a lot of things about that, and wrote a code. But I'm not getting th...
Hello world! I am wondering if it is possible to render a scene to multiple render targets in a single pass (or anything faster than drawing it several times through client code). I want to optimize some code that is being rendered to several textures of varying dimensions (512 by 512, 256 by 256, 128 by 128 and 64 by 64 for example). ...
I'm just testing this stuff out, so I don't need an alternate approach (no GL extensions). Just hoping someone sees an obvious mistake in my usage of GLES. I want to take an bitmap of a glyph that is smaller than 32x32 (width and height are not necessarily powers of 2) and put it into a texture so I can render it. I've first created an ...
