Introducing Corona VR workflow

Good news everyone! Render Legion is working with to provide one-click, integrated solution for distributing virtual reality tours!


2016 is shaping up to be the year of Virtual Reality! It has been around for 15+ years, but only now is it finally looking usable and widely accessible. New mobile VR devices like Samsung Gear VR or Google’s upcoming DayDream will make it easier than ever to deliver a simple and quality VR experience to everyone.

We plan to stay ahead with this popular technology, so we’d like to introduce you to the “Corona VR” project, which is co-developed with the promising young startup

UPBP: Light scattering in arbitrary volumes

Hello Coronauts,

this is Jarda, a new member of the Corona developer team. I’m a university professor and computer graphics researcher, and I’ve decided to use some of my know-how to help propel the development of Corona. Today, I’d like to follow up on Ondra’s post and share with you one of our exciting research results that will be presented at SIGGRAPH in Vancouver.

In this project, we have looked into unbiased rendering of light scattering in arbitrary volumes (or participating media, if you will). And when I write arbitrary, I do mean it. We set to develop an algorithm that can render fog, olive oil, wine, soap, wax, … (just about any volume that can scatter light) using a single unified approach. We call the resulting algorithm Unified points, beams and paths (UPBP) and I believe the results look pretty good:

Corona and Research?

We would like to introduce a new chapter on our blog, which we simply call Research corner“. As you might know, Ondrej and Jaroslav are not only great programmers, but also researchers. They have published many interesting studies and achieved great results in the academic field. We have decided to occasionally publish interesting news and articles from their research on our blog in hope to spark more interest in “what’s really under the layer of C++ code”

In the rest of this article, Ondra describes the latest project he had worked on.
