Hi, I want to update data stored in textures using FBOs. My problem is that my textures are large and thus takes too long to update. Since only small parts of the textures need to be updated between each frame, I want to just update these parts.
I believe this can be done by rendering into a smaller buffer and then copy the data into the correct part of the texure using glBlitFrameBuffer. As I understand this will copy the data without touching CPU memory, but it is still not very fast. Am I right? Does anyone know of a better way? Help much appreciated! Thank you!
