Here's a fun free resource for y'all - fake cubemap interior mapping for Unity! They even light okay. Pretty performant at 2 cubemap calls, and if you don't want the objects in the middle of the room it can be as low as 1. #unity3d #gamedev #opensource

It’s pretty much a straight shoot up into the third dimension for the first 2 tests. However, for the 3rd, instead of projecting a 1D line from a 2D shape as above, we instead project a 2D shape onto a 2D surface. To do this, we decompose the rotated 3D rectangular prism into its composite triangles

3. Pick one of the boxes to define a set of axis as areference frame. Rotate the whole world in such a way that one box is now perfectly aligned with the axis. Then, we project to each axis. If any of the projections do not overlap, we can guarantee that the boxes do not overlap either.

2. Iterate the points of one of the boxes and check the overlap. If there are any points within the box, the box is overlapping.

First lets think about the problem in 2 dimensions. There’s 3 tests we can run to check if these rotated boxes overlap, shown in the diagram above. We run these tests from cheapest => most expensive.
1. Generate two axis-aligned boxes and run a quick AABB check as a broad phase check.

Have you ever had two arbitrarily rotated and sized rectangular prisms in 3D space, and wanted to check if they’re intersecting? I know I have! But how can we actually do this well? #gamedev

It's even got different voxel modes!

It's got an editor which is... Functional. Honestly, this thing is made to solve problems, not be pretty, and it's more of a look into how my brain works than a UX design.

It's got custom materials per voxel, per surface! Including texture support (using Texture2DArray, which has some platform support implications iirc)

It's got mesh optimization!
