Creating and modifying a virtual reality environment just got a lot easier thanks to software being released today by Imverse, an EPFL spin-off. The secret behind Imverse’s program, which works much like a photo editor, is a three-dimensional rendering engine based on 3-D pixels called voxels. The rendering engine can be used for other virtual reality applications as well, such as depicting real people. The startup’s initial target market is the movie and video game industry.
