    Shaders Making vertex buffers pixelated

    Hello GMC, So from my understanding, vertex buffers/ primitives are shot straight to the GPU. Ignoring all game resolutions and only using your monitor's display resolution. I know to get texture coords, it's v_vTexcoord. I'd like to know an equivalent or similar way to this. The problem I'm...

    Heya! I've been trying to find a way to convert the application surface into a texture so I can use it in shaders. However, any attempts to draw this surface texture result in the image being repeated into infinity. This is an undesirable effect, as I want the surface to be drawn a single time...

    Shaders Mode 7 Shader Issue

    I was making a shader to simulate the super Nintendo's Mode 7, and it more or less worked, but whenever I squished the image, another sprite would appear along side it as if it was part of that image. The two images are not part of the same sprite and I don't currently call the other sprite...
