It’s not just because Digital Foundry’s Alex Battaglia and John Linneman can build rooms that call attention to concepts like “specularity,” and “bounce lighting” and “differentiated reflective surfaces.” Its because the voxelized world is optimal for the real-time demands of ray tracing. Minecraft, using the mod Sonic Ether’s Unbelievable Shadows, makes for a surprisingly good test space. ![]() Here is a surprisingly watchable technical demonstration from Digital Foundry - using Minecraft of all things - to point out its applications - like your username casting a shadow.
