Denoised ReSTIR Rendering Algorithm

One of the really cool projects that I worked on for Huawei R&D UK was the Denoised ReSTIR render algorithm. ReSTIR GI is Nvidia's invention and it is one of the best ways to quickly solve the rendering equation for global illumination. However the output of the ReSTIR GI algorithm isn't noise free, so a few denoising rendering passes are necessary. My implementation of ReSTIR GI uses hardware accellerated raytracing and it looks pretty amazing when you're able to move around in a 3D scene and get a fully converged screen image more than 60 times per second. Have a look at screenshots from the realtime demo here.

TurnTool Technology

From 2001 to 2011 I was CTO and co-founder in a company called TurnTool that created a proprietary 3D graphics engine able to display 3D inside the browser and this was long before WebGL worked in all browsers. Here are a few video-clips from projects that I worked on and that uses the TurnTool engine.

OpenFreeForm Technology

OpenFreeForm is a resolution independent GUI system where all shapes are defined by mathematical curves making it possible to represent any GUI in any resolution while maintaining sharp edges and perfect antialiasing.
The OpenFreeForm GUI system handles all graphical operations directly on the GPU and have by some been called the new .SVG format.
By using the userfriendly editor you can draw any scape in a clear and efficient way and test how your design respond to changes in resolution and aspect ratio.
