This was my first one.

Too reflective for something supposedly colored with crayons |
I kind of like that, but I was hoping for a softer look from the spheres, they just seem too mirror-like for having been colored with crayon. To get rid of those reflections and create a more diffuse effect, I turned off reflections altogether.
I created a small scene of textured spheres, each with a different one of the pictures my kids and I worked on in the last few weeks. I fiddled with the scene for awhile too, moving the spheres and camera around, and monkeying with the number and colors of the lights. I spent too long on this.
Below you can see some of the images my dallying produced. First is the Halloween sphere.

Welcome to the Halloween Ball! |

This image is aliased, and the light near the ground in front is too pink. |

I replaced that pink light with a dim white one, and I sent out 25 rays per pixel for this image. |

Due to the perspective viewing, the ones near the edge resemble colored Easter eggs. |
Well, that was fun. Perhaps it was a waste of time, but it was fun nonetheless. And tomorrow morning my kids will be happy to see their artwork plastered onto my computer screen.
When I mentioned this little experiment to a graphics friend of mine, he wondered whether we could achieve the effect of coloring things with crayon computationally rather than photographically. I thought that was a great question.
I love these images! The perspective issue can be fixed. Can you work crayon art into your final project?
ReplyDeleteAre you thinking of an orthographic projection instead of a perspective one? I think that would keep things from getting squashed at the edges, right?
ReplyDeleteI was thinking eventually I might try to implement a lopsided ellipsoid object (i.e. an egg) for my geometry collection. I could put a few of them into a scene where they're sort of peeking out from behind other objects, like "hidden" easter eggs. Everything would be textured with crayon art.
As for my final project, I was hoping to do something like clouds or smoke or something. Maybe it would look cool to have some dynamic fog moving through a scene like the one I described above? I think the juxtaposition of old-school crayon with swirly fog could be interesting. Though it could be super cheesy if the fog doesn't look good.
Depending on how that worked out, the next thing to do might be to render this foggy crayon scene for the dome, from a point of view down near the ground in between the eggs. When we play it in the dome, I could imagine it really creating the a cool effect. I don't whether or not it could be raytraced fast enough to be interactive, but even a movie might be cool.
