Web18 de abr. de 2024 · Something that comes up often in real-time rendering engines is the need to run a full-screen pixel shader. It’s pretty common for screen space effects, to name the big ones: screen-space reflections and screen-space ambient occlusion. However, in order to render a full-screen pixel shader pass, you need to fill the screen with geometry. WebTo save the OpenGL to .png format, I first recommend the PNGwriter.
