// 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 :)
