Nvidia presents Voxel Global Illumination in Unreal Engine 4

Voxel Global Illumination in Unreal Engine 4

Nvidia presents Voxel Illumination Did you know that Nvidias new GPU's, GeForce GTX 970 and GeForce GTX 980 already supports VXGI? You don't know what VXGI is? Well, it's a new lightning technologie which can make games look way more realistic. VXGI stands for Voxel Global Illumination and is developed by Nvidia. What this really means for gamers and developers now is presented in some Graphicdemos, especially in one made by "Byzantos".

VXGI was announced in Fall 2014. This technologie is exclusive for Nvidia GPU's with the Maxwell-Chipset, namely GeForce GTX 970, 980 and of course the high priced Titan X.

Working on voxel basis, games now aren't only depending on prerendered and simulated lightsources, but actually allows a real time lighting system. This means every obejcts can stray and illuminate light in real time. A good example would be a piece of metal which is highly lighted. This piece will stray the light and also act like a lightning source itself. Nvidia VXGI allows to make games look more realistic then ever before.

So what does that mean for game developers? Well, Voxel Global Illumination is in beta state, it's far away from being production ready. Like always, this techdemo shows what is possible. It is a nice overview of what will be possible in the future. And say what you want, this demo looks just amazing. But like we all know, it's a long way from demo to playable. For the moment Nvidia VXGI only works with an outdated and highley customized verion of Unreal Engine 4, also particles wont illuminate light at this stage of the development. So it's still a long way to go.

Nonetheless the techdemos are amazing and are a good look into the future of computergames. Watch the Videos and settle up your own opinion.
