Updating a texture in OpenGL with glTexImage2D

43 In modern OpenGL there are 4 different methods to update 2D textures: glTexImage2D - the slowest one, recreates internal data structures. glTexSubImage2D - a bit faster, but can't change the parameters (size, pixel format) of the image. Render-to-texture with FBO - update texture entirely on GPU, very fast. WebMultitexture Example. ¶. This example blends two textures: the image mtexture1.png of the letter K and the image mtexture2.png of an orange circle. You should see an orange K clipped to a circle.
