I was bored, so I’m making some 3d tech demos

#1: [https://arcade.makecode.com/S96688-42156-14265-62216](https://arcade.makecode.com/S96688-42156-14265-62216)

You can change the size of the block, make custom sprites and models. One problem is that it reduces the frame rate.

Here are 3 ways to avoid this:

1. the size limit has to be 32 (just to be safe)

2. the extra space limit is 48 (again just to be safe and not have the corners cut off)

3. have the size small (16 for example) and scaling it (if you want to have some snes mode 7 transformations)

here is an example:[https://arcade.makecode.com/S96688-42156-14265-62216](https://arcade.makecode.com/S96688-42156-14265-62216)

The size limit is not really limiting since you can double the size with this extension: [robo-technical-group](https://github.com/robo-technical-group)/**[pxt-arcade-image-transform](https://github.com/robo-technical-group/pxt-arcade-image-transform)**

And that’s it! I’ll post more tech demos soon
