Author: Tapani Pälli <[email protected]> Date: Tue Jun 9 12:26:48 2015 +0300 mesa: add GL_RED, GL_RG support for floating point textures Mesa supports EXT_texture_rg and OES_texture_float. This patch adds support for using unsized enums GL_RED and GL_RG for floating point targets and writes proper checks for internalformat when format is GL_RED or GL_RG and type is of GL_FLOAT or GL_HALF_FLOAT. Later, internalformat will get adjusted by adjust_for_oes_float_texture after these checks. v2: simplify to check vs supported enums v3: follow the style and break out if internalFormat ok (Kenneth) Signed-off-by: Tapani Pälli <[email protected]> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=90748 Reviewed-by: Kenneth Graunke <[email protected]> (cherry picked from commit 5b0d6f5c1bc3f7bd37c6efebf48f80ca6ff3ef87) Nominated-by: Mark Janes <[email protected]> --- src/mesa/main/glformats.c | 37 ++++++++++++++++++++++++++++++++++--- 1 file changed, 34 insertions(+), 3 deletions(-) diff --git a/src/mesa/main/glformats.c b/src/mesa/main/glformats.c index 4fc85ab..3374637 100644 --- a/src/mesa/main/glformats.c +++ b/src/mesa/main/glformats.c @@ -2292,8 +2292,18 @@ _mesa_es3_error_check_format_and_type(const struct gl_context *ctx, break; case GL_HALF_FLOAT: - if (internalFormat != GL_RG16F) - return GL_INVALID_OPERATION; + case GL_HALF_FLOAT_OES: + switch (internalFormat) { + case GL_RG16F: + break; + case GL_RG: + if (ctx->Extensions.ARB_texture_rg && + ctx->Extensions.OES_texture_half_float) + break; + /* fallthrough */ + default: + return GL_INVALID_OPERATION; + } break; case GL_FLOAT: @@ -2301,6 +2311,11 @@ _mesa_es3_error_check_format_and_type(const struct gl_context *ctx, case GL_RG16F: case GL_RG32F: break; + case GL_RG: + if (ctx->Extensions.ARB_texture_rg && + ctx->Extensions.OES_texture_float) + break; + /* fallthrough */ default: return GL_INVALID_OPERATION; } @@ -2361,8 +2376,19 @@ _mesa_es3_error_check_format_and_type(const struct gl_context *ctx, break; case GL_HALF_FLOAT: - if (internalFormat != GL_R16F) + case GL_HALF_FLOAT_OES: + switch (internalFormat) { + case GL_R16F: + break; + case GL_RG: + case GL_RED: + if (ctx->Extensions.ARB_texture_rg && + ctx->Extensions.OES_texture_half_float) + break; + /* fallthrough */ + default: return GL_INVALID_OPERATION; + } break; case GL_FLOAT: @@ -2370,6 +2396,11 @@ _mesa_es3_error_check_format_and_type(const struct gl_context *ctx, case GL_R16F: case GL_R32F: break; + case GL_RED: + if (ctx->Extensions.ARB_texture_rg && + ctx->Extensions.OES_texture_float) + break; + /* fallthrough */ default: return GL_INVALID_OPERATION; } _______________________________________________ mesa-commit mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/mesa-commit
