Demo Effect - Chunky-pixel Effects

Chunky-pixel Effects

Effects based on software rendering into chunky-pixel framebuffers were typical in the mid and late 1990s and were usually first implemented on the PC or Falcon030. They became popular as systems with pixel-addressable high speed video memory and faster processors (to allow for more demanding real-time calculations) became common.

• Effects based on static screen-to-texture lookup tables
  • Texture-mapped tunnels and other objects rotating around their axis of symmetry
  • Wobblers, rotators and other similar effects for 2D images
  • Objects that reflect or refract underlying bitmap images
• Texture-mapped tunnel with freely moving camera, typically based on realtime raytracing
• Rotozoomer
• Mandelbrot zoomer
• Fire effect and other effects based on 2D filters and feedback
• Heightfield landscape (often called "voxel landscape")
• 2D bump mapping
• Metaballs

Some of these effects were later ported to planar pixel machines such as the Amiga, without relying on chunky to planar conversion. For example, the group Sanity implemented a rotozoomer using a combination of pre-rendered planar bitmaps and copper effects.
