From e272f5efe910b09242dd42c4044aa85bfe9b1710 Mon Sep 17 00:00:00 2001 From: vortex Date: Fri, 13 May 2011 21:37:16 +0000 Subject: [PATCH] Multisampling initialisation moved from vid_sdl to gl_backend. Make cubemaps array dynamic (segments are allocated on load), this uses less memory, and MAX_CUBEMAPS was raised. git-svn-id: svn://svn.icculus.org/twilight/trunk/darkplaces@11147 d7cf8633-e32d-0410-b094-e92efae38249 --- gl_backend.c | 29 +++++++++++++++++++++++++++++ gl_backend.h | 1 + gl_rmain.c | 47 ++++++++++++++++++++++++++++++++++++++--------- quakedef.h | 4 ++-- vid_sdl.c | 21 --------------------- vid_shared.c | 13 +++++++++++++ 6 files changed, 83 insertions(+), 32 deletions(-) diff --git a/gl_backend.c b/gl_backend.c index 5fbf7979..0efde344 100644 --- a/gl_backend.c +++ b/gl_backend.c @@ -2120,6 +2120,35 @@ void GL_CullFace(int state) } } +void GL_MultiSampling(qboolean state) +{ + switch(vid.renderpath) + { + case RENDERPATH_GL11: + case RENDERPATH_GL13: + case RENDERPATH_GLES1: + case RENDERPATH_GL20: + case RENDERPATH_GLES2: + if (vid.support.arb_multisample) + { + if (state) + qglEnable(GL_MULTISAMPLE_ARB); + else + qglDisable(GL_MULTISAMPLE_ARB); + CHECKGLERROR + } + break; + case RENDERPATH_D3D9: + break; + case RENDERPATH_D3D10: + break; + case RENDERPATH_D3D11: + break; + case RENDERPATH_SOFT: + break; + } +} + void GL_AlphaTest(int state) { if (gl_state.alphatest != state) diff --git a/gl_backend.h b/gl_backend.h index 82b9ed4f..8f6e5ab1 100644 --- a/gl_backend.h +++ b/gl_backend.h @@ -40,6 +40,7 @@ void R_SetStencil(qboolean enable, int writemask, int fail, int zfail, int zpass void GL_PolygonOffset(float planeoffset, float depthoffset); void GL_CullFace(int state); void GL_AlphaTest(int state); +void GL_MultiSampling(qboolean state); void GL_ColorMask(int r, int g, int b, int a); void GL_Color(float cr, float cg, float cb, float ca); void GL_ActiveTexture(unsigned int num); diff --git a/gl_rmain.c b/gl_rmain.c index 354160da..6c0b6505 100644 --- a/gl_rmain.c +++ b/gl_rmain.c @@ -282,7 +282,7 @@ typedef struct cubemapinfo_s cubemapinfo_t; int r_texture_numcubemaps; -cubemapinfo_t r_texture_cubemaps[MAX_CUBEMAPS]; +cubemapinfo_t *r_texture_cubemaps[MAX_CUBEMAPS]; unsigned int r_queries[MAX_OCCLUSION_QUERIES]; unsigned int r_numqueries; @@ -3741,14 +3741,36 @@ rtexture_t *R_GetCubemap(const char *basename) { int i; for (i = 0;i < r_texture_numcubemaps;i++) - if (!strcasecmp(r_texture_cubemaps[i].basename, basename)) - return r_texture_cubemaps[i].texture ?
