Finally! Trig! now I understand!
This was just a visual demonstration to go with a discussion that I started in the forms about the ray tracer that I wrote in Scratch. I don't plan on doing a demonstration of cross product since I didn't use one in the ray tracer.
I can fix it so that it says that the length is a scalar.
Thinking of making a cross-product tutorial? (THAT'S one that would have helped me when I was trying to learn this stuff!) =)
Nice, nice. I like these tutorials! (Is this for a class or something? Or are you just genuinely an amazing person?) If I had to give any feedback, I'd say make it clearer that the dot product of two vectors is NOT a third vector (which is what I would instinctively look for if I were Average Joe Viewer); that it's a scalar, just a number. Maybe even toss in a couple of numbers for example like you did with Tutorial #2.
I'm glad someone has found them useful.
Useful set of tutorials.
