Shader Week, Day 6

Todays shader tutorial was about keeping an offscreen buffer which we can update continually.

In the image to the left we invert the colors every second.

The right image was supposed to be smoke, but the tutorial was very math heavy but thin on how to do the implementation. So I skipped the smoke tutorial and made a script myself that draws a circle at the mouse position (cursor not visible in gif) and fades the image by 0.9 every frame.

Good thing the cursor isn’t visible though. Somehow the mouse X/Y-movement was inverted, and coordinates messed up. But not enough time to fix tonight, as I’m only using an hour a day.
