| − | ===Anti-aliasing===
| |
| − | A graphics rendering technique used to reduce or eliminate jagged or stepped edges (aliasing artefacts). It works by applying various methods such as super-sampling, multi-sampling, or post-processing filters to improve the smoothness and visual quality of the image, particularly when displaying diagonal lines, curves, or fine details.

| |

| − | ===CRT===
| |
| − | A digital effect used to emulate the appearance of old cathode ray tube monitors and televisions. It does this by adding effects such as scan lines, colour distortion and curvature to the image to recreate the look. It is particularly popular because the majority of developers have used the unique properties of a CRT to their advantage to create certain effects.

| − | ===DDT===
| |
| − | Data-Dependent Triangulation Shaders look at the square plane formed by the four nearest neighbours (a basic image resizing technique that assigns each pixel in the resized image the colour value of the nearest pixel in the original image). They divide the square plane into two triangular planes. The pixels are bilinearly interpolated using only the three points of the triangles to which they belong.

| − | ===Dithering===
| |
| − | A technique used to increase the amount of colour and shading that can be produced on a system. The effect is achieved by using lines or dots which are then blurred by the low quality NTSC signals (composite or RF) used by the system.
