    Kitten Koder was talking about Ray Tracing in another thread and I've always been fascinated with it. Here are a few images I found that are very realistic:

    It's a beautiful art form, but then I can also see the mathematics involved which is beauty to me. Traving the path of each beam of light ... bouncing it off virtual spaces ... filtering through translucent objects ...

    Am I weird?

    Weird?

    Finding beauty in things beautify?

    Seems eminently human to me.

    Oooh, I am human after all! :tongue:

    Math to me is beauty, all forms of it, raytracing is one of those you actually get to see more than the numbers, fractals to (chaos theory).

    The big picture with the "globes" just takes too long to load, so I have not seen it in full yet, but the others are cool.

    I'm not an artist and I would say that is an art form. I'm still not sure what the point of tracing rays is though. I'll make a mental note to go and look up more information on this as there is no reason for you to try and explain it here.

    But weird? No, I wouldn't say that you are weird because of this hobby. Weird, yes, but not because of the hobby. :lol:

    Oh and thanks to YWN666 for giving me a visual point of reference as to the outcome of raytracing.

    PS the globes finally loaded. Nice picture.

    The movie industry. All those computer generated movies and effects use raytracing.

    My "problem" with this is not what it is used for so much as why?

    As I said, I'm not an artist. When dealing with colors, you grab a crayon (or on the computer you click on the "color" button) and voila! you have the color you want. Why go through all that work just to find the color you want? It's right there in your box of 64 crayons! :lol:

    Now getting serious... This seems interesting to me. Until you had mentioned it, I had never heard of it before. I will have to look into it some more, because, I don't understand the need for it so to speak.

    Anyone else interested in this, I just searched and found this article:

    No, the better question is "why not?"

    It's an art medium, and like all artistic mediums, why not use it? People like what they can do with it, and many like how it looks. Look at a lot of the recent movies done with the medium, like "Delgo" and "The Matrix", all impossible without computer generated graphics, raytracing more specifically.

    It'd be like asking why bother using clay, or why bother with airbrushing. Instead of a potters wheel we use the computer, instead of brushes we have a mouse, it's art, it's creativity, and it's fun when you get into it. Almost addictive once you get the hang of it.

    I read that link I provided up until it got to the math part. Okay, I am going to be 48 in a week... shhh! don't tell anyone... and I hated Geometry. It was the one math class that I absolutely despised. I had to stop reading there.

    As for KK's post about "why not?", I understand that. It is like solving a puzzle and who isn't intrigued by trying to solve a puzzle?

    I'm still confused about how it works and all that. I can see by YWN666's post and the link I posted the output of Raytracing, but (again, I am not graphically inclined so this will sound dumb) but where does the input come from? A digital picture? When Leonardo Da Vinci painted the Mona Lisa he started with a woman in front of him and he painted her picture. She was the input. Do you take a digital picture of say a Carnival Cruise Ship (yes, I'm thinking of cruising right now) and trace the rays through that picture or do you create the picture from your "mind's eye"?

    I'm sorry, all of these questions sound stupid, but I'm curious about the process.

    Nope. I am forever fascinated by how well computers can simulate the real world.
