Back to tetrahedrons

Canvas Demo

I want to make a rotating tetrahedron. So far, I have four random points which I reposition to get a 'better' tetra.

Procedural Art

Canvas Demo

Torus

First draw a circle out of points, then another set of circles of points around each point on the original circle. I have a wireframe of each point, one after the other. I drew quads, but they need to be sorted far to near. Kewl procedural art, tho! 8-P

Taking a break from the other thing...

Torus

First draw a circle out of points, then another circle of points around each point on the original circle. I have a wireframe of each point, one after the other. Next I need to draw quads.

Okay, Mars...

Canvas Demo

Mars has 6.28 mb atmo, ~24 g/m^3 CO2, 600 mg of Ar and 180 mg of N2. If we go with .9 kg/m^3 N2 we need to compress 5*10^3 m^3 of Martian Atmospheric N2 for every m^3 of habitat. A cubic kilometer of atmo could provide N2 for a 5 hectare/4m tall mars hab.

Big Damn Space Opera, 2006... RIP

I found a page from my Big Damn Space Opera from 13 years ago… a galactic map and some sketches of a hunter and a trike using ovals. The map is a *very* simplified map of the Galaxy. FTL is via a network of constructed ‘wormhole’ pairs (which, BTW, are sentient/sapient beings). Complex Alpha and the Spinward Rim Alliance are largely located in one geographic (Galactographic?) region. About 90% of the wormholes in this part of the Galaxy date from ~300K BCE. The WH finger leading to Earth/Sol connects Complex Alpha at a point anti-spinward of the SRA and Ilshan, the center of civilization for the ‘Wider Galaxy’ (the known worlds, species and interstellar empires), is near the center of CA. The Markov Imperium has worlds in CA, but for the most part its’ star systems are scattered all over Galaxy (this implies that the WHs of the MI network predate the Florescence which built most of the WHs in Complex Alpha, and this is mostly the case, except for where it connects to CA of course). The Hunter (an extinct species and super power) homeworld system connects to CA at a point near the rim of the galaxy, but like the Earth/Sol it is several wormhole links away from CA proper. Humans are known to the wider galaxy but officially uncontacted. In fact, aliens have been visiting and meddling and recently ramped up massive abductions to supply unwilling cannon fodder. The fastest route to Krasnaya and Sparrowgrad, a human accidental colony is technically through the Markov Imperium, ‘actually skirting the edges of it at that Avian HW’ (and I have no recollection of WTF I’m talking about (yeah, Jim…). A hunter is an eight-limbed tiger centaur with seven digits on each hand or paw. The design is not optimized for tool-use, but the Tester was rushed, and when you’re rushing you get rotten uplift, dongma? I owe myself a decent sketch and animation of Trikes while I’m at it. Oddies and Ubers, too...

Emerson & Rhoda

Emerson and Rhoda

These two worlds orbit each other around their shared center of mass. The barycenter is several radii outside of Emerson. This is a follow on to my Barnard's Star worldbuild, link here.

Triangulating the Surface of a Sphere

Stereo Projection to a Sphere

I'm going to try this again, looping and animating with setInterval. First to place pts until I have a hundred of them spaced at least 65 px apart. Then make a triangle by finding the two closest points, and the pt closest to the midpoint of that edge. Then I need to build out triangles off of those three edges. An edge is unique and can belong to one or two triangles, so I need to make a list of triangles and edges, adding new 'open' edges and removing 'closed' edges. I also want to have a list of 'open pts', removing pts as I use them. I need to check adjacent open edges before I make a new triangle with an 'open pt' which is farther away than the other end of an adjacent open edge.
