// here lies the GREAT JUSTICE RENDERER
|
|
// TODO :
|
|
// - CORE STUFF
|
|
// 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
|
|
// - 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 truly convert MD2s to MD3s with proper scale offset to just dump the data into VRAM
|
|
// o need full translation and rotation support from CON to attach to game world or tags
|
|
// o need to blend between frames
|
|
//
|
|
// the renderer should hopefully be pretty solid after all that
|
|
// the rest will be a bliss :)
