From 23caf20169ac38436ee9c13914f1d6aa7cf6bb5e Mon Sep 17 00:00:00 2001 From: Keith Whitwell Date: Thu, 16 Nov 2000 21:05:34 +0000 Subject: Move the transform and lighting code to two new directories math: Provides basic matrix and vector functionality that might be useful to multiple software t&l implementations, and is used by core mesa to manage the Model, Project, etc matrices. tnl: The real transform & lighting code from core mesa, including everything from glVertex3f through vertex buffer handling, transformation, clipping, lighting and handoff to a driver for rasterization. The interfaces of these can be further tightened up, but the basic splitting up of state and code move is done. --- src/mesa/drivers/ggi/ggimesa.c | 2 +- src/mesa/drivers/glide/fxapi.c | 582 +-------------------------------------- src/mesa/drivers/glide/fxdd.c | 41 ++- src/mesa/drivers/glide/fxdrv.h | 11 +- src/mesa/drivers/glide/fxsetup.c | 2 + src/mesa/drivers/osmesa/osmesa.c | 13 +- src/mesa/drivers/svga/svgamesa.c | 4 +- src/mesa/drivers/x11/xm_api.c | 9 +- src/mesa/drivers/x11/xm_dd.c | 5 +- src/mesa/drivers/x11/xm_line.c | 3 +- src/mesa/drivers/x11/xm_span.c | 3 +- src/mesa/drivers/x11/xm_tri.c | 5 +- 12 files changed, 43 insertions(+), 637 deletions(-) (limited to 'src/mesa/drivers') diff --git a/src/mesa/drivers/ggi/ggimesa.c b/src/mesa/drivers/ggi/ggimesa.c index 125aefcfb6..764ccba803 100644 --- a/src/mesa/drivers/ggi/ggimesa.c +++ b/src/mesa/drivers/ggi/ggimesa.c @@ -508,7 +508,7 @@ void GGIMesaSwapBuffers(void) { GGIMESADPRINT_CORE("GGIMesaSwapBuffers\n"); - FLUSH_VB(GGIMesa->gl_ctx, "swap buffers"); + _mesa_swapbuffers( GGIMesa->gl_ctx ); gl_ggiFlush(GGIMesa->gl_ctx); if (GGIMesa->gl_vis->DBflag) diff --git a/src/mesa/drivers/glide/fxapi.c b/src/mesa/drivers/glide/fxapi.c index ea5f816258..f3a6431aec 100644 --- a/src/mesa/drivers/glide/fxapi.c +++ b/src/mesa/drivers/glide/fxapi.c @@ -43,579 +43,6 @@ */ -/* fxapi.c - 3Dfx VooDoo/Mesa interface */ - - -/******************************************************************** - * - * Function names: - * fxMesa....
