WebThere was a stricter limitation on the images in the original GL_EXT_framebuffer_object extension, namely that all attachments have the same size and internal format. However, since it has found its way into OpenGL 3.0+ core (and was from there exported back as the more advanced GL_ARB_framebuffer_object extension) they loosened these restrictions. WebIf no corresponding internal format is available, or the GL can not compress that image for any reason, the internal format is instead replaced with a corresponding base internal format. If the internalformat parameter is GL_SRGB , GL_SRGB8 , GL_SRGB_ALPHA , or GL_SRGB8_ALPHA8 , the texture is treated as if the red, green, or blue components are …
