+# Overview
+
+This is just a simple algorithm for the TI-84+ CE to render simple voxels quickly and dynamically. For now it is just an engine/algorithm, but once it is in a ready stage, it will be used to make a couple games.

+### TODO
+
+ - [ ] Add common voxel coordinate lookup table to optimize rendering
+ - [ ] Add functionality to render planes and polygons
+ - [ ] Darken colors for the further away from the camera it is (volumetric fog)
+ - [ ] Optimize algorithm (sacrifice of accuracy is acceptable, and may make the scene loop less calculated and and definitive - more natural)
+ - [ ] Find a way to render everything unclipped (will need help!!)
+ - [ ] Render screen coordinates using 8 bit values instead of 16 - will allow the right side of the screen to be used for stats
+
+### Changelog
+
+***v0.1.0*** - First demo
