allow us to build without D3D support under Windows (just define NO_DIRECT3D) clean up TMAP flags fix a couple of minor OpenGL state change issues with spec and env map rendering make sure we build again for OS X (OGL extension functions work a little different there) render targets always need to be power-of-2 to avoid incomplete buffer issues in the code when we disable culling in opengl_3dunlit be sure that we re-enable it on exit of function re-fix screenshots add true alpha blending support (with cmdline for now since the artwork has the catch up) draw lines with float positioning, to be more accurate with resizing on non-standard resolutions don't load cubemaps from file for D3D, not sure how to do it anyway update geometry batcher code, memory fixes, dynamic stuff, basic fixage, etc.

|
|
*
|
|
* Revision 2.10 2005/03/03 02:39:14 bobboau

|
*
|
|

|
|
*
|
|
* Revision 2.6 2004/02/16 11:47:33 randomtiger
|
|
* Removed a lot of files that we dont need anymore.
|
|
* Changed htl to be on by default, command now -nohtl
|
|
* Changed D3D to use a 2D vertex for 2D operations which should cut down on redundant data having to go though the system.
|
|
* Added small change to all -start_mission flag to take you to any mission by filename, very useful for testing.
|
|
* Removed old dshow code and took away timerbar compile flag condition since it uses a runtime flag now.
|
|
*
|
|
* Revision 2.5 2004/02/15 06:02:32 bobboau
|
|
* fixed sevral asorted matrix errors,
|
|

|
|
*
|
|
* Revision 2.4 2003/11/02 05:50:08 bobboau
|
|
* modified trails to render with tristrips now rather than with stinky old trifans,
|
|
* MUCH faster now, at least one order of magnatude.

|
|
* Added incomplete code to allow selection of non-standard modes in D3D (requires new launcher).
|
|
* As well as initialised in a different mode, bitmaps are stretched and for these modes
|
|
* previously point filtered textures now use linear to keep them smooth.
|
|
* I also had to shuffle some of the GR_1024 a bit.
|
|
* Put my HT&L flags in ready for my work to sort out some of the render order issues.
|
|
* Tided some other stuff up.
|
|
*
|
|
* Revision 2.1 2003/03/18 10:07:02 unknownplayer
|
|

|
|
*
|
|

|
|
*
|
|
* Revision 2.0 2002/06/03 04:02:23 penguin
|
|
* Warpcore CVS sync
|
|
*
|
|
* Revision 1.1 2002/05/02 18:03:07 mharris
|
|
* Initial checkin - converted filenames and includes to lower case
|
|
*
|
|
*
|
|
* 4 6/29/99 10:35a Dave
|
|
* Interface polygon bitmaps! Whee!
|
|
*
|
|
* 3 12/06/98 2:36p Dave
|
|
* Drastically improved nebula fogging.
|
|
*
|
|
* 2 10/07/98 10:53a Dave
|
|
* Initial checkin.
|
|
*
|
|
* 1 10/07/98 10:49a Dave
|
|
*
|
|
* 17 4/10/98 5:20p John
|
|
* Changed RGB in lighting structure to be ubytes. Removed old
|
|
* not-necessary 24 bpp software stuff.
|
|
*
|
|
* 16 4/09/98 7:58p John
|
|
* Cleaned up tmapper code a bit. Put NDEBUG around some ndebug stuff.
|
|
* Took out XPARENT flag settings in all the alpha-blended texture stuff.
|
|
*
|
|
* 15 4/09/98 4:38p John
|
|
* Made non-darkening and transparent textures work under Glide. Fixed
|
|
* bug with Jim's computer not drawing any bitmaps.
|
|
*
|
|
* 14 3/23/98 5:00p John
|
|
* Improved missile trails. Made smooth alpha under hardware. Made end
|
|
* taper. Made trail touch weapon.
|
|
*
|
|
* 13 11/21/97 11:32a John
|
|
* Added nebulas. Fixed some warpout bugs.
|
|
*
|
|
* 12 10/15/97 5:08p John
|
|
* added flag for alpha tmap
|
|
*
|
|
* 11 3/10/97 5:20p John
|
|
* Differentiated between Gouraud and Flat shading. Since we only do flat
|
|
* shading as of now, we don't need to interpolate L in the outer loop.
|
|
* This should save a few percent.
|
|
*
|
|
* 10 3/05/97 7:15p John
|
|
* took out the old z stop tmapper used for briefing.
|
|
*
|
|
* 9 12/10/96 10:37a John
|
|
* Restructured texture mapper to remove some overhead from each scanline
|
|
* setup. This gave about a 30% improvement drawing trans01.pof, which is
|
|
* a really complex model. In the process, I cleaned up the scanline
|
|
* functions and separated them into different modules for each pixel
|
|
* depth.
|
|
*
|
|
* 8 11/07/96 2:17p John
|
|
* Took out the OldTmapper stuff.
|
|
*
|
|
* 7 11/05/96 4:05p John
|
|
* Added roller. Added code to draw a distant planet. Made bm_load
|
|
* return -1 if invalid bitmap.
|
|
*
|
|
* 6 10/26/96 1:40p John
|
|
* Added some now primitives to the 2d library and
|
|
* cleaned up some old ones.
