Aqsis new core prototype, interactive viewer!

So here it is - words cannot describe what you are about to see, you have to watch this for yourselves.



From the Aqsis development blog :

"This blog has been pretty quiet for a while, but aqsis development has been coming along behind the scenes. During the aqsis-1.6 development last year I focussed a lot on making aqsis faster. After working on this for a while it became obvious that some major changes were needed for the code to be really fast. In particular, the aqsis sampler code is geared toward dealing with single micropolygons at a time, but it seems better for the unit of allocation and sampling to be the micropolygon grid as a whole. This was just one of several far-reaching code changes and cleanups which seemed like a good idea, so we decided that the time was right for a rewrite of the renderer core. Broadly speaking, the goals are the following:

* Speed. Simple operations should be fast, while complex operations should be possible. The presence of advanced features shouldn't cause undue slowdowns when they are disabled.
* Quality. Speed is good, but not at the cost of quality. Any speed/quality trade offs should be under user control, and default settings should avoid damaging quality in typical use cases.
* Simplicity. This is about the code - the old code has a lot of accumulated wisdom, but in many places it's complex and hard to follow. Hopefully hindsight will lead us toward a simpler implementation.

Fast forward to the better part of a year later - development has been steady and we've finally got something we think is worth showing. With Leon heading off to the Blender conference, I thought an interactive demo might even be doable and as a result I'm proud to present the following screencast.



There's several important features that I've yet to implement, including such basic things as transparency, but as the TODO file in the git repository indicates, I'm getting there. The next feature on the list is to fix depth of field and motion blur sampling which were temporarily disabled when implementing bucket rendering.

Edit: I realized I should have acknowledged Sascha Fricke for his blender-2.5 to RenderMan exporter script which was used by Paul Gregory in exporting the last example from blender. Thanks guys!"

"Just to clarify, this is not a demonstration of an interactive viewer for RIB editing. This is the newly under development main core. So, what you’re seeing there is the actual renderer, rendering microplygons (Reyes) at 40 fps. We’re just displaying it in an interactive framebuffer, rather than bucket at a time, to show how fast it really is. It’s not using GPU, purely CPU, exactly what you’ll get when you render with Aqsis.
I should also point out that it’s not complete yet, this is the first demonstrable stage of the core re-engineer, there’s more still to go in before it’s even up to current Aqsis feature levels, but rest assured, when it’s finished, this is going to be fast."
