Gallery description
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.

What a great resource! But...where are Parts 1 and 4?
That's strange. I was fairly sure that they were in here. Should be there now.
since raytracers can be slow, here is a tip: download, and play them in "TURBO SPEED"! to do this, hold shift and click on "extras", then click on "Set single stepping", and finally, click on "Turbo speed". Much faster!
how are these really "tutorials"? They don't explain how.
Kewl!
I will remove the posts that are off topic from the projects in this gallery.

A post about version 1.2 was posted here: (link to forum)">(link to forum) There is a variable block with that lets you retrieve the current background.

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.
ok i will. Thank you for accepting my request. Here it is: (link to project)">(link to project)
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?
