Working on a custom 3d renderer.

Here’s the first version:[https://arcade.makecode.com/S92337-43349-49808-46555](https://arcade.makecode.com/S92337-43349-49808-46555)

Right now the fps is a little bit slow and you can’t rotate but at least you can render a single cube.

(Also, for some reason the top layer doesn’t want to show up)

Is it possible that in the future you can add like height to blocks to make 2 story buildings or towers without teleporting into a level and then and to make like tables or stairs?

this is going to become the gem of an extension for ray casting (TRANSLATION: I believe in you, don’t give up)

A new update!

Made a 2nd one that uses the PolyMesh extension!

V1 :[https://arcade.makecode.com/S30783-69633-18444-27618](https://arcade.makecode.com/S30783-69633-18444-27618)

Now it runs smooth and you can rotate the cube (and also the textures render properly)
