// TODO :
|
|
// - recursive drawrooms with cliplane stack (support for full portal engine with occlusion queries)
|
|
// - crossed walls (tier drops stones)
|
|
// - skies
|
|
// - mirrors
|
|
// - fullbright (multitexture OR)
|
|
// - masks and sprites ! (use sortcnt and regular drawmask or recode it ?)
|
|
// - classic shading
|
|
// --------------------- CLASSIC LIMIT ---------------------
|
|
// - mdsprites (tags)
|
|
// - lights (dynamic phong)
|
|
// - dynamic shadowmaps
|
|
// - normalmap palette (unified gpu program, parallax mapping)
|
|
// - shadow volumes
|
|
// - hardware particles
|
|
// - multitextured decals ? (on models too)
|
|
// --------------- FIRST PUBLIC RELEASE LIMIT --------------
|
|
// - horizon mapping (precalculate the horizon maps and store them into the gl cache ?)
|
|
// - post processing ([HDR-]bloom and possibly DOF)
|
|
// - MD5 (hardware skinning ?)
