Raw Normal View 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 :)
