Priority: medium Bug ID: 74329 Assignee: dri-devel@lists.freedesktop.org Summary: Please expose OES_texture_float and OES_texture_half_float on the ES3 context Severity: minor Classification: Unclassified OS: Linux (All) Reporter: org.freedesktop@io7m.com Hardware: All Status: NEW Version: 10.0 Component: Drivers/DRI/R600 Product: Mesa

Hello.

Original discussion on mailing list:

http://lists.freedesktop.org/archives/mesa-users/2014-February/000761.html

Essentially, for the purposes of testing code in an ES3 context as it would be run on an ES2 context (that is, taking the paths the code would take based on the extensions present on ES2), it would be nice if the ES3 context exposed OES_texture_float and OES_texture_half_float.

The current ES3 context on this hardware exposes GL_EXT_texture_rg and GL_EXT_color_buffer_float, and can therefore definitely support OES_texture_float and OES_texture_half_float. All that would (apparently) be required would be for floating point textures to be specified in an ES2 compatible manner (with format and internalformat set to GL_RED|GL_RG, and type set to GL_FLOAT).
