From 8e39ad2cd67d49be40ff0822f3269affdf83d601 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Tue, 6 Feb 2001 21:42:48 +0000 Subject: [PATCH] Overhaul of texture image handling. 1. gl_texture_image struct's Data pointer points to images in driver's format. 2. Added FetchTexel() function pointer to struct gl_texture_image. 3. Changed Driver Tex[Sub]Image functions, return void now. 4. Texture storage/fetch code in new texstore.c file. 5. Removed texture.[ch] - functions moved to state.c Note: FX driver updates not finished yet. --- src/mesa/Makefile.X11 | 4 +- src/mesa/drivers/glide/fxdd.c | 11 +- src/mesa/drivers/glide/fxddtex.c | 65 +- src/mesa/drivers/glide/fxdrv.h | 20 +- src/mesa/drivers/osmesa/osmesa.c | 22 +- src/mesa/drivers/x11/xm_dd.c | 27 +- src/mesa/main/Makefile.X11 | 4 +- src/mesa/main/context.c | 3 +- src/mesa/main/dd.h | 217 +++-- src/mesa/main/dlist.c | 7 +- src/mesa/main/mtypes.h | 16 +- src/mesa/main/state.c | 160 +++- src/mesa/main/teximage.c | 1906 +++++++------------------------------- src/mesa/main/teximage.h | 19 +- src/mesa/main/texstate.c | 3 +- src/mesa/main/texstate.h | 11 +- src/mesa/main/texstore.c | 1068 +++++++++++++++++++++ src/mesa/main/texstore.h | 143 +++ src/mesa/swrast/s_texture.c | 839 ++++++----------- src/mesa/swrast/s_triangle.c | 50 +- src/mesa/swrast/s_tritemp.h | 4 +- src/mesa/tnl/t_imm_exec.c | 3 +- src/mesa/tnl/t_imm_fixup.c | 3 +- 23 files changed, 2209 insertions(+), 2396 deletions(-) create mode 100644 src/mesa/main/texstore.c create mode 100644 src/mesa/main/texstore.h diff --git a/src/mesa/Makefile.X11 b/src/mesa/Makefile.X11 index fe57194..f764cac 100644 --- a/src/mesa/Makefile.X11 +++ b/src/mesa/Makefile.X11 @@ -1,4 +1,4 @@ -# $Id: Makefile.X11,v 1.42 2001/02/03 08:41:03 gareth Exp $ +# $Id: Makefile.X11,v 1.43 2001/02/06 21:42:48 brianp Exp $ # Mesa 3-D graphics library # Version: 3.5 @@ -103,7 +103,7 @@ CORE_SOURCES = \ teximage.c \ texobj.c \ texstate.c \ - texture.c \ + texstore.c \ texutil.c \ varray.c \ vtxfmt.c \ diff --git a/src/mesa/drivers/glide/fxdd.c b/src/mesa/drivers/glide/fxdd.c index 1750778..d6ba79b 100644 --- a/src/mesa/drivers/glide/fxdd.c +++ b/src/mesa/drivers/glide/fxdd.c @@ -1108,12 +1108,11 @@ void fxSetupDDPointers(GLcontext *ctx) ctx->Driver.TexImage2D = fxDDTexImage2D;
