WebWe have to tell OpenGL the size of the rendering window so OpenGL knows how we want to display the data and coordinates with respect to the window. We can set those dimensions via the glViewport function ... Note that processed coordinates in OpenGL are between -1 and 1 so we effectively map from the range (-1 to 1) to (0, 800) and (0, ... Web24 de ago. de 2013 · 420. August 24, 2013 08:31 PM. On D3D9, the definition of pixel coordinates is stupidly shifted so that the centre of the top-left pixel lines up perfectly with the top-left edge of the screen. i.e. all the pixels are shifted by half a pixel in that direction, so you need: uv = ndc * 0.5 + 0.5 + 0.5/num_Pixels; great pottery throwdown 2023 tonight https://ryanstrittmather.com
