OES_texture_float does not specify floating point render target support. Our implementation has this because it is 'expected' by the corresponding WebGL extension. Related discussion in the khronos public bugzilla: <a href="https://www.khronos.org/bugzilla/show_bug.cgi?id=729">https://www.khronos.org/bugzilla/show_bug.cgi?id=729</a> There's also bunch of bugs in the internal bugzilla. WebGL extension specification mentions that new implementation should not implement render target support but implement WEBGL_color_buffer_float which maps with EXT_color_buffer_half_float: <a href="https://www.khronos.org/registry/webgl/extensions/OES_texture_float/">https://www.khronos.org/registry/webgl/extensions/OES_texture_float/</a> So, to put it short our implementation is wrong in allowing render targets to be created with GL_FLOAT and GL_HALF_FLOAT. Unfortunately fixing this means that we will loose some nice deferred rendering webgl demos enabled by current implementation, we could think of having override to allow this later (?) Will investigate a proper fix.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
