Vector texture maps using the OpenGL Shading Language: article, demo & source

Textures are used everywhere in computer graphics, for realism and detail. Storing texture data as sampled pixel-based images limits their resolution and requires large amounts of data if the surfaces are to be viewed close up. This article “Beyond the pixel: towards
infinite resolution textures” describes a method in which render curved contours of arbitrary shape and high complexity can be represented compactly and accurately, stored as texture data and rendered using the OpenGL Shading Language at an arbitrary resolution with very good real-time performance on consumer hardware. It also presents all the details on how to actually implement it, including a demo with full source code.
