* Revision 2.17 2007/01/07 13:13:39 taylor
|
|
* cleanup various bits of obsolete or unused code
|
|
*
|
|
* Revision 2.16 2006/11/06 05:42:44 taylor
|
|
* various bits of cleanup (slight reformatting to help readability, remove old/dead code bits, etc.)
|
|
* deal with a index_buffer memory leak that Valgrind has always complained about
|
|
* make HTL model buffers dynamic (get rid of MAX_BUFFERS_PER_SUBMODEL)
|
|
* get rid of MAX_BUFFERS
|
|
* make D3D vertex buffers dynamic, like OGL has already done
|
|
*
|
|
* Revision 2.15 2006/10/06 09:56:42 taylor
|
|
* clean up some old software rendering stuff that we don't use any longer
|
|
* remove grzbuffer.*, since all it did was give us 3 variables, which were moved to 2d.*
|
|
*
|
|
* Revision 2.14 2006/09/08 06:20:14 taylor
|
|
* fix things that strict compiling balked at (from compiling with -ansi and -pedantic)
|
|
*
|
|
* Revision 2.13 2006/05/27 17:07:48 taylor
|
|
* remove grd3dparticle.* and grd3dbatch.*, they are obsolete
|
|
* 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 2.12 2006/05/13 07:29:52 taylor
|
|
* OpenGL envmap support
|
|
* newer OpenGL extension support
|
|
* add GL_ARB_texture_rectangle support for non-power-of-2 textures as interface graphics
|
|
* add cubemap reading and writing support to DDS loader
|
|
* fix bug in DDS loader that made compressed images with mipmaps use more memory than they really required
|
|
* add support for a default envmap named "cubemap.dds"
|
|
* new mission flag "$Environment Map:" to use a pre-existing envmap
|
|
* minor cleanup of compiler warning messages
|
|
* get rid of wasteful math from gr_set_proj_matrix()
|
|
* remove extra gr_set_*_matrix() calls from starfield.cpp as there was no longer a reason for them to be there
|
|
* clean up bmpman flags in reguards to cubemaps and render targets
|
|
* disable D3D envmap code until it can be upgraded to current level of code
|
|
* remove bumpmap code from OpenGL stuff (sorry but it was getting in the way, if it was more than copy-paste it would be worth keeping)
|
|
* replace gluPerspective() call with glFrustum() call, it's a lot less math this way and saves the extra function call
|
|
*
|
|
* Revision 2.11 2005/12/16 06:48:28 taylor
|
|
* "House Keeping!!"
|
|
* - minor cleanup of things that have bothered me at one time or another
|
|
* - slight speedup from state switching
|
|
* - slightly better specmap handling, fixes a couple of (not frequent) strange and sorta random issues
|
|
* - make sure to only disable HTL arb stuff when in HTL mode
|
|
* - handle any extra lighting pass before spec pass so the light can be applied properly
|
|
*
|
|

|
|
*
|
|
* 12 11/03/97 10:08p Hoffoss
|
|
* Changed gr_get_string_size to utilize an optional length specifier, if

|
|
*
|
|
* 7 6/17/97 12:03p John
|
|
* Moved color/alphacolor functions into their own module. Made all color
|
|

|
|
* grsoft.
|
|

|
|
* 6 6/12/97 5:04p John
|
|
* Initial rev of Glide support
|
|
*
|
|
* 5 6/11/97 5:49p John
|
|
* Changed palette code to only recalculate alphacolors when needed, not
|
|
* when palette changes.
|
|
*
|
|
* 4 6/06/97 4:41p John
|
|
* Fixed alpha colors to be smoothly integrated into gr_set_color_fast
|
|
* code.

|
* Made all the radar dim in/out
