VoxelSpace

The „Voxel Space“ engine from the 90th has only very little to do with what we call voxel today. It it basically a raycasting engine for height maps [0]. It is very limited. You can‘t look up and down more than 20 degrees and you can‘t even render houses, cars or trees. [0] https://github.com/s-macke/VoxelSpace

Hey HN, I've been inspired by Michael Fogelman's Craft [1] and other links around here over the years to learn more about 3d graphics programming. comanche has been my path to learning. It can currently render 30 different maps - 29 of them were reverse engineered by Sebastian Macke [2] from the game Comanche (1992). There's no actual relation to the game, I just remember playing it as a kid and the file format is convenient (two pngs, one representing height, the other color). There is a lone map by me. The goal is to build an actual game, but the focus will always be to have very readable source so that others can learn from it. I've written a blog post further describing the goals behind it as well as discussing the basics of graphics programming and the advantage of using WebGL [3]. There are plenty of links to resources for further l

Very similar technique (raycasting), but for different type of data. https://github.com/s-macke/VoxelSpace The text in the README describes the technique very well. The JavaScript code is a little bit more complicated to read because most of the source contains the usual organizational tasks around the algorithm (initialization, keyboard input, ...). But this is also true for the provided C-code of this article.
