// here lies the GREAT JUSTICE RENDERER
// TODO :
2008-03-30 11:43:24 +00:00
// - CORE STUFF
// o there's also the texture alignment problem Hunter reported (san andreas fault)
2008-03-30 16:08:18 +00:00
// o also sliding doors are still fucked up sometimes (like under the bar in E1L2)
2008-03-30 11:43:24 +00:00
// o port glowmaps and detail maps from hacked polymost (:(
// o shading needs a lot of work
// o remove all the IM matrix crap and write real functions now that it works
// - SPRITES
// o port sprite panning and fullbrights from hacked polymost (:(
// - SKIES
// o figure a better way to handle ART skies - maybe add symetric caps that would fade to black like a big gem or something wow this is a long column lol ;0)
// o implement polymost skyboxes
// - MDSPRITES
2008-05-24 09:37:09 +00:00
// o need to truly convert MD2s to MD3s with proper scale offset to just dump the data into VRAM
2008-03-30 11:43:24 +00:00
// o need full translation and rotation support from CON to attach to game world or tags
2008-06-01 08:58:06 +00:00
// o need to blend between frames
2008-03-30 11:43:24 +00:00
//
// the renderer should hopefully be pretty solid after all that
// the rest will be a bliss :)
