WebGL_NEAREST (also known as nearest neighbor or point filtering) is the default texture filtering method of OpenGL. When set to GL_NEAREST, OpenGL selects the texel that center is closest to the texture … 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.
