Spacetime warping non-Euclidean portals in Brahma Engine
Just made the portals actually work and be passable by the player, with possible resizing. The time feel can also alter in accordance with spatial scaling, producing a time dilation effect for a smaller player.
Some portals simply connect remote regions, some resize spacetime and everything that travels through it. This is an example of a process that is not possible in the physical world, but can be implemented in a game engine.
The image seen by the player becomes increasingly noisy and blurry as smaller amounts of light get into the entrance pupil, being the effect of smaller optics and faster shutter speeds, as simulated by my photorealistic rendering pipeline. This is demonstrated through a 64x shrink, yielding 64^3=262144 times less light per frame and turning day into night.
The final location features walking on a surface of a cube. Each cube represents a face of a cube, allowing light and objects to travel around cube's surface which appears like an infinite plane due to space warping.
The player is still invisible, and voxel objects are not rendered when mirrored, so consider this a work in progress.
