Geomerics are making a proposal to the UK Technology Stategy Board (TSB) for "disruptive technology" funding to germinate an idea we've been discussing for a long while now. The proposal is a very public one via a youtube video submission, and the "5th judge" will be public feedback! So I'm looking for as much input as possible to improve this idea. Naturally, this is funding proposal, rather than a tech one, so apologies if it's short on tech details.
UPDATE: The video has been submitted. Thanks to all that contributed! Please check it out and leave feedback on the TSB site - you are the 5th judge so your opinion matters!
Here is the final text for the 2 minute video.
Efficient Real-Time Graphics Through A Domain Specific Language
Parallel computing is the next major challenge for software development as chip manufacturing has hit physical limits that require us to go parallel to do more. However, writing parallel software is a hard problem, and requires a new approach.
Computer graphics leads parallel hardware development and is the best known parallel application. But the same hardware and software that drives the graphics in your modern PC is also used by the scientific and medical imaging communities. Advances in graphics frequently have a wider impact in these fields. But despite its apparent suitability, graphics still suffers from a serious programmability gap. There is not yet a good way of driving the hardware effectively. It is widely accepted that without further innovation, faster hardware will not deliver comparatively improved visual quality.
So our goal is to bridge the programmability gap for graphics. By doing so we will tap the unexploited potential of the new power-efficient parallel hardware, providing an important product for the games and graphics industry, while making progress into the wider parallel programming problem.
With full TSB funding, we would draw on our expertise to prototype an alternative graphics pipeline, taking the novel approach of structuring it as a domain specific language (DSL). We will show that new graphics algorithms can be efficiently developed in this language and provide solutions to a range of outstanding problems affecting game and graphics developers that are hard or impossible to realise with existing approaches.
These challenges include:
- higher fidelity images (anti-aliasing)
- cinematic lens effects (bokeh, depth of field)
- complex illumination and shadowing
- semi-transparent materials, such as glass or water
- volumetric rendering, such as fog and smoke
We intend to show a step-change in visual quality, and demonstrate a new parallel programming model with wider applicability. The TSB funding would allow us to build the foundation for a middleware product Geomerics would commercialise in the games and graphics industry. With partial funding we will scale the prototype to deliver a vertical slice focussing on a single rendering challenge.
With its worldwide reputation for game graphics, its close ties with hardware manufacturers and its relationships with academia, Geomerics is ideally placed to carry out this development.
There is some good background material on this topic from this year's Beyond Programmable Shading Course from SIGGRAPH 2010. Of particular relevance is, Johan Andersson's "5 Major Challenges in Interactive Rendering" - another crowd-sourced proposal.
