// here lies the GREAT JUSTICE RENDERER
|
|
// TODO :
|
|
// - CORE STUFF
|
|
// o put all the sector/wall geometry in VBOs
|
|
// o wall palette problem (toxic waterfall in the abyss is blue)
|
|
// o there's also the texture alignment problem Hunter reported (san andreas fault)
|
|
// o also sliding doors are still fucked up sometimes (like under the bar in E1L2)
|
|
// 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
|
|
// o polymer.c possibly needs to be split in several source files
|
|
// o some crap really needs factorization
|
|
// o ... possibly more important stuff I don't have in mind right now
|
|
// - 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
|
|
// o need to reimplement them - hopefully the loader can be reused without too much hassle
|
|
// o need full translation and rotation support from CON to attach to game world or tags
|
|
// o need to put frames into VBOs and blend between them
|
|
//
|
|
// the renderer should hopefully be pretty solid after all that
|
|
// the rest will be a bliss :)
