This is a gallery of the tutorials that go along with the scratch forum about a ray-tracer that I wrote in Scratch.
This will cover all of the basic math and how it applies to the Scratch program.
Most of the math explained here is general purpose and these instructional programs can help you learn how they are applied to this type of program.

how are these really "tutorials"? They don't explain how.

and, how do you get the updated version of scratch (1.2)? And, is there a round block with "background" on it? If so, they would be very useful. You wouldn't have to use variables anymore.

You have to create variables to store the size and color. Post a link to the project so that we can discuss more about it there.

I have a project, that when you change the sprite size or color, and then go to eraser, i want it to remember (recognize) the same pen size or color after going back to drawing. Although it may be easier to make with the pen down, i made my painting project a sprite that stamps when mouse is down (because it is an airbrush sprite. I have asked this question to many other people, and i really want to be able to know how to do it. Can you try out a small project that i can download that expresses this idea?
