raze/polymer/eduke32/build/include/polymer.h
helixhorned 922aa3ca8b Classic-like visibility/fog for OpenGL modes, r_usenewshading 2 (new default). 
Implemented using GL_LINEAR fog. The only source of difference (besides the
obvious indexed vs. true color) should now be the distance constant, which
still had to be determined experimentally.  Polymer implements this mode in
its fog fragment program part.

Parallaxed skies are always drawn with full visibility, I'm not sure if there
are any maps that expect otherwise.

Also, accidentally committed: factor out initialization code from
polymost_printext256() into gen_font_glyph_tex(), small game.c changes.

Raw Blame History

// here lies the GREAT JUSTICE RENDERER
// TODO :
// - CORE STUFF
// o there's also the texture alignment problem Hunter reported (san andreas fault)
// o RTT portals (water)
// o clip mirrors/portals to their planes
// o merge mirrors/portals from the same plane
// - SPRITES
// o sprite panning
// - SKIES
// o skyview
// - MDSPRITES
// o need full translation and rotation support from CON to attach to game world or tags
//
// the renderer should hopefully be pretty solid after all that
// the rest will be a bliss :)
