The HP Visualize-FX devices provide hardware support for the following operations:

  • Generating vectors

  • Wide lines

  • Write-enabling planes and selecting individual banks in the frame buffer

  • Writing pixels to the frame buffer with a given replacement rule

  • Moving a block of pixels within the frame buffer

  • Double-buffering per window

  • Flat shaded rectangles

  • Dithering and HP Color Recovery technology

  • Overlay plane transparency (X Windows)

  • Gouraud Shading

  • Positional and directional lighting calculations

  • Anti-aliased lines

  • Alpha transparency

  • Hidden surface removal with Z-buffer

  • Z-buffering of voxels

  • Model geometry transformations

  • Optional hardware acceleration of texture mapping

  • Polygon offset

The hpvisx device driver supports the high performance graphics devices described in subsequent sections.
