Success Part 2!
September 28th, 2004 - 12:31 pm
A tremendous success today. My parsing utility wrapped up and I was able to use my tetrahedron class in conjunction with the parsing utility to create an arbitrary complex geometrical structure from tetrahedrons. Check the picture out. It was created from 832 tetrahedrons created from 1840 faces. The faces are made up of 1248 edges, and the edges consume 241 unique vertices in 3D space.
I am highly amused (and well on my way to my masters).
IseGeometry Information:
Version: 1
Type: grid
Dimension: 3
Vertices: 241
Edges: 1248
Faces: 1840
Elements: 832
Regions: R.Substrate
Materials: Silicon
That’s pretty damn cool. You might consider having an edge always traced as black, unless the faces that meet there are black, and then trace in some other arbitrary color.
The corner closest to the point-of-view, as well as the top-left corner are lost.
Also very interesting is the way the darker colors in the top-back corner produce an optical illusion that makes it seem disproportional and not in proper perspective.
I’m actually not in charge of the rendering of it so there’s not much I can do to that effect. I just need to describe the structures to the particle simulator. The real trick is in the fact that the input comes in as a sort of messed up relative list of cartesian coordinates, and the input to the particle simulator is a totally different set of coordinate systems that is something like polar coordinates (You first make an elementary object, and then you rotate it, and the place it in a volume). Making this translation wouldn’t be too hard if the simulator had built in tetrahedrons. Alas, tetrahedrons are not one of its types, so I had to create my own tetrahedrons by creating a cube and cutting away the faces with 4 more cubes such that the tetrahedron is created. To be fair, most of the time, we will be looking at wire frame renderings to see how a particle of radiation interacts with the target geometry.
When I first generated the object, I thought that something was wrong too. The colors do make it look like the perspective is wrong or it is not exactly a cuboid. The colors are pseudo random so it just so happens that for the chosen seed, the colors work out to make that effect.
I’m happy for you. : )
now i know where the colors of the late 70s and early 80s went to die.
looks like the Rubix Cube of the Damned ..

Someone pointed me to this link: http://www.bash.org/?261931
nox solves the Rubix Cube O’ the Damned and waits for the female attention a feat of that magnitude will surely entail….
lsmsrbls might be excited by a feat like that, but only if you don’t rub shit in her pants.
I don’t get your inside joke. I do, however, like what I hear. I would like to subscribe to your newsletter.
Read the link she posted above.

I got the joke now….reading is a good thing!

That’s the question you have to ask yourself…..am I that guy? Who knows!?!?!?!
if that story is true, why would the guy post it online? To absolve himself??

He was probably telling random people on the intarweb, and one of them decided to post it on bash.org.
If he really wanted to absolve himself, he should have hit up http://grouphug.us.
