Any word on ANY render to texture spec?!

[KRONOS]

I am trying to do some stuff with shadow maps and I'am tired of the pbuffer crap.

Where the heck is super buffer and EXT_render_target?! We haven't heard anything from EXT_render_target and it has been almost 5 months and then I read that super buffers may be left out because there is almost no hardware support.

EXT_render_target started good with a lot of discussion, but then nothing more from it. Is it dead? Is it ready? Is it out on vacation? What?

I am really tired of waiting!
We don't even have any news or info regarding both extensions, so I can wait 1, 2, 3 or 9 more months (nobody knows) for a simple thing like this?

If there is no solution until the end of the year, tell us (so I might start porting to D3D).

To ATI and NVIDIA people out here: any news?!

(and sorry to create a thread mostly to complain, but anyone can join in... )

joined...

Me too !

I'm in to get not only news but at the very least an EXT, would prefer an ARB though.

Same here, i'm definitelly waiting for this extension, some news would be good to hear

I want it too. Todays engines use image compositing rendering approach and good RTT is necessary for that. PBuffers are good but not enough. For example I need to share depth buffer between main backbuffer and some PBuffer. MRT can help but MTR is just a set of backbuffers (not textures!).

@KRONOS

I hear some rumors about RTT in D3D. RTT in D3D are slower than pbuffers! So stick to GL.

We're working on it. Just like with a Carmack game, it will be ready when it's ready. If you think about it, we're making a pretty significant change to the way OpenGL works. It would really be a shame to botch it up, don't you think?

Like was said the the OpenGL BoF at SIGGRAPH, pretty much all of the major issues with the current spec have been worked out (finally!), and we're polishing off the last details. There's still a few things left, but I can see a light at the end of the tunnel. I'm pretty sure it's not a train, too.

Working on what? Is it the super buffers after all? What about EXT_render_target?! What can we expect?

Can we see a spec? Please...

yooyo: are you sure?!

They, basically, said that ARB_superbuffers is dead, and that they're going with render_target (which will now be ARB_render_target).

Can we see a spec? Please...

I imagine it isn't much too different from what we saw in the preliminary EXT_render_target spec, but obviously a bit more mature. My real question is this.

During the EXT_RT discussions, a lot was made of making this extension very restrictive (buffers needing to be the same size, etc), and building on top of it to allow for hardware that can loosen the restrictions. Also, a lot was made on having another extension based on EXT_RT to allow for render-to-vertex-array-esque functionality. Are either of those fronts progressing, and will they be available when ARB_RT comes out?

Well seeing as though you can now sample a texture in a vertex shader a render-to-vertex-array extension is kind of redundant, don't you think?
