Summary: 3D textures don't work on GLES2
Product: Mesa
Version: git
Platform: Other
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: Mesa core
AssignedTo: mesa-dev@lists.freedesktop.org
ReportedBy: n...@linux.intel.com
Created an attachment (id=40883)
--> (https://bugs.freedesktop.org/attachment.cgi?id=40883)
Example
GLES2 on Mesa is advertising the GL_OES_texture_3D extension but the GLSL
compiler seems to get very upset if you try to use it. Attached is an example.
I get these errors with it:
fragment shader info:
0:1(12): warning: extension `GL_OES_texture_3D' unsupported in fragment shader
0:2(22): error: invalid type `sampler3D' in declaration of `tex'
0:7(31): error: `tex' undeclared
0:0(0): error: no matching function for call to `texture3D(, vec3)'
link info:
linking with uncompiled shader
Mesa: User error: GL_INVALID_OPERATION in glUseProgram(program 1 not linked)
Mesa: User error: GL_INVALID_OPERATION in glGetUniformfv(program)
Mesa: User error: GL_INVALID_OPERATION in glUniform(program not linked)
It might be better not to advertise the extension if it's not going to work.
