Polymer Deficiencies

This is a list of problems in the Polymer renderer that need to be fixed. Plagman is master of everything Polymer.

• certain major optimizations remain to be done (the sole issue is lack of time)
• implement new sky support; would solve:
  • limited to one skybox
  • level geometry is displayed through skyboxes when it should not
  • showview command does not work
  • changing skies at runtime
• no voxel support
• doesn't save known good geometry in savegames for use as a fallback when map effects become corrupt, revealing errors that otherwise would be avoided
• not hooked up to TX's Sector Effector-based ROR (which remains useful for retrofitting existing maps)
• polymer does not modify roll when transforming HUD models during changes to rotscrnang (per polymost).
• ATI cards cast no shadows with any spotlights.
• Better sprite/model sector tracking; would solve:
  • Models disappearing from view
  • Lights affecting sprites through walls
• Translucent/masked-out texels of sprites draw incorrectly in front of translucent TROR boundaries (may be multiple issues)

1. Non-hightile, lighting enabled: in trueror1.map, shoot with the chaingun at the TROR water. The water will not show where the splash texture has masked-out texels. Bug disappears with lighting disabled.
