From e333035c47a6a4cc88f0f9ca2bced500538bebae Mon Sep 17 00:00:00 2001 From: Tapani Pälli Date: Thu, 12 Feb 2015 14:33:53 +0200 Subject: mesa: fix OES_texture_float texture render target behavior MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Current implementation allowed usage of unsized type texture GL_FLOAT and GL_HALF_FLOAT as a render target as this was 'expected behavior' by WEBGL_oes_texture_float and is also allowed by the oes-texture-float WebGL test. However this broke some ES3 conformance tests that do not accept such behavior. Patch sets such an fbo incomplete as expected by the ES3 conformance tests. Textures with sized types like RGBA32F will still continue to work as render targets. v2: code style cleanups (Ian Romanick, Matt Turner) Signed-off-by: Tapani Pälli Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=88905 Reviewed-by: Ian Romanick Cc: "10.5" --- src/mesa/main/fbobject.c | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'src') diff --git a/src/mesa/main/fbobject.c b/src/mesa/main/fbobject.c index dae9d4ed2eb..30536229764 100644 --- a/src/mesa/main/fbobject.c +++ b/src/mesa/main/fbobject.c @@ -781,6 +781,18 @@ test_attachment_completeness(const struct gl_context *ctx, GLenum format, att->Complete = GL_FALSE; return; } + + /* OES_texture_float allows creation and use of floating point + * textures with GL_FLOAT, GL_HALF_FLOAT but it does not allow + * these textures to be used as a render target, this is done via + * GL_EXT_color_buffer(_half)_float with set of new sized types. + */ + if (_mesa_is_gles(ctx) && (texImage->TexObject->_IsFloat || + texImage->TexObject->_IsHalfFloat)) { + att_incomplete("bad internal format"); + att->Complete = GL_FALSE; + return; + } } else if (format == GL_DEPTH) { if (baseFormat == GL_DEPTH_COMPONENT) { -- cgit v1.2.3
