My bad. fbo_color_attachments is not what I recalled from when I
first looked at the Tegra information. Thanks for correcting me.
NVIDIA bad too. OES_texture_half_float does not change the OpenGL
ES 2.0 specification language that says no (internal) formats
other than a small list of integer formats are color-renderable.
They should have made an extension.
As far as I can tell there is no NV extension on the Tegra which exposes half-float rendering. If you are thinking of GL_NV_fbo_color_attachments, that extension only adds additional color attachment points. The Tegra's support for fp16 render targets seems to be solely defined under its support for GL_OES_texture_half_float on page 15 of the Tegra developer documentation ( http://developer.download.nvidia.com/tegra/docs/tegra_gles2_development.pdf ). If I'm wrong and there is a separate NV extension please send a pointer to it.
