Generating 3D scenes from 2D images more efficiently – Mobile NeRF rendering using Vulkan on Adreno GPU

Co-written with Aleksandra Krstic, Alex Bourd and Shuaib Arshad.

Suppose you came home from vacation with a few dozen photos from different perspectives of the Eiffel Tower or the Taj Mahal or Michelangelo’s David. What if you wanted to “walk” around them again, if only virtually?

Reducing Rendering Work and Memory Operations in Stereoscopic Scenes – New Multiview Extensions for Vulkan

A common XR technique is to use multi-viewport for viewports and scissor out different regions of each eye, but multi-viewport ignores clears and is incompatible with other XR extensions. It can also prevent foveation and slow down the rendering work.
