From 4741dbcbbc2514de370a760f4b78a17491014555 Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Wed, 1 Oct 2008 15:51:56 -0700 Subject: Unify ARB_depth_texture and SGIX_depth_texture The ARB extension is a superset of the older SGIX extension. Any hardware that can support the SGIX version can also support the ARB version. In Mesa, any driver that supports one also supports the other. This unification just simplifies some bits of code. --- src/mesa/main/teximage.c | 18 ++++++++---------- 1 file changed, 8 insertions(+), 10 deletions(-) (limited to 'src/mesa/main/teximage.c') diff --git a/src/mesa/main/teximage.c b/src/mesa/main/teximage.c index b0a2d6ddb3d..4a419fde261 100644 --- a/src/mesa/main/teximage.c +++ b/src/mesa/main/teximage.c @@ -241,13 +241,12 @@ _mesa_base_tex_format( GLcontext *ctx, GLint internalFormat ) } } - if (ctx->Extensions.SGIX_depth_texture || - ctx->Extensions.ARB_depth_texture) { + if (ctx->Extensions.ARB_depth_texture) { switch (internalFormat) { case GL_DEPTH_COMPONENT: - case GL_DEPTH_COMPONENT16_SGIX: - case GL_DEPTH_COMPONENT24_SGIX: - case GL_DEPTH_COMPONENT32_SGIX: + case GL_DEPTH_COMPONENT16: + case GL_DEPTH_COMPONENT24: + case GL_DEPTH_COMPONENT32: return GL_DEPTH_COMPONENT; default: ; /* fallthrough */ @@ -526,9 +525,9 @@ static GLboolean is_depth_format(GLenum format) { switch (format) { - case GL_DEPTH_COMPONENT16_ARB: - case GL_DEPTH_COMPONENT24_ARB: - case GL_DEPTH_COMPONENT32_ARB: + case GL_DEPTH_COMPONENT16: + case GL_DEPTH_COMPONENT24: + case GL_DEPTH_COMPONENT32: case GL_DEPTH_COMPONENT: return GL_TRUE; default: @@ -2297,8 +2296,7 @@ _mesa_GetTexImage( GLenum target, GLint level, GLenum format, return; } - if (!ctx->Extensions.SGIX_depth_texture && - !ctx->Extensions.ARB_depth_texture && is_depth_format(format)) { + if (!ctx->Extensions.ARB_depth_texture && is_depth_format(format)) { _mesa_error(ctx, GL_INVALID_ENUM, "glGetTexImage(format)"); return; } -- cgit v1.2.3
