A Red Figure Greek vase rotates and tilts, originally prepared with WebGL and GLSL shader highlights. The sun gradually rises over a landscape originally prepared with JavaScript and indexed colors.
What are Procedural Graphics?
Procedural graphics refer to programmed processes which create color values, highlights, shapes and other digital image techniques. Procedurally generated moving graphics often apply to textures for 3D meshes, with GLSL Shaders in the C language, providing special effects such as animated blurring, interactive highlights, glowing, masks, fire and explosions.
Two dimensional procedural video also covers a wide range of techniques such as translucency (alpha), global composite operations, the appearance of 3D with light and shadow, masks, color shifts and filters.
