Ray-tracing Images

Here are a few images and short videos created with ray-tracing software. The images are linked to the videos and full-size images. For the latest Divx codec, click the Divx image here:
A couple of things for work.
The image on the left is an initial rendering. The final rendering doesn't have the glare at the top.
An animated atom. (speed is greatly reduced of course)
A collection of images within another image. This is based on my master bedroom. The room dimensions are exact with the correct number and spacing of bricks and ceiling tiles. The curtains are a row of cylinders along a sin wave, and I replaced the 70's paneling with nicer wood walls. The light fixture is a Zumtobel Cardan Spirit.
The first image is a test of planting 300,000+ plant objects (each tree and all its attached and detached leaves are one object) on an imported terrain file. I modeled a tree for this one in a few minutes. The tree kind of sucks, but it serves its purpose. I just realized too that the front door is open a few degrees, making it look crooked. The second was to get an idea of what a tile I looked at at Home Depot would look like in my bathroom instead of the plastic and linoleum. The third is a map of Iceland. The fourth was for a class.
My attempt to demonstrate the result of two harmonic oscillations after the topic was discussed in a Univ. Physics III class. This is a low-quality mpg of the original on the left - about 5.3mB. The other is one cycle at about 256Kb.
Testing variables for a macro that creates blobs of "snow" on the trees. There is a house behind the most prominent tree in the left image. The right image has a lot of inconsistencies with lighting and seasons, but it's just a test for the blobs of snow. The lamp that was just put in was made by Gilles Tran.
A test-run sketching y = x3.

Arclength: The arclength value displayed is calculated by adding the distances between the spheres. As the number of spheres increases, the collection more closely resembles the true curve of the function (from x=-2 to x=1). If only I had made a note of what the function is. The idea is still the same. As the distances between the spheres decrease, the value for the arclength approaches the true value for the length of the segment. The animation consists of 1000 frames.

Fuzzy Math. Just for fun.

derivative (slope) of sin.
The sine wave consists of hundreds of sphere objects. The slope at the tangent line is calculated by dividing the change in the y-coordinates by the change in x-coordinates for the spheres on either side. The slope value itself is returned as the height for the tracing sphere below. The line given was not programmed in as cos(x), but as the collection of these tracing spheres.

This was made as an illustration of a part that we needed made for our lab. The illustration went to the machinist along with the cad diagrams.
