I have a commission of sorts, to model or at least do some sort of animation of a human expansion wave across the Milky Way. At this point I'm just smearing stars across my background...

Spinning Habitat Interior
Looking up the inside of a cylindrical habitat. The different heights represent 'hills' and 'valleys' on the interior.

Spiral Points
I need to loop around and splat out some pts and triangles on the inner surface of a cylinder.

Spiral Me Some Triangles...
First the points, then a line spiraling from pole to pole. Finally, but probably not, make triangles! We're looking down on the North Pole. I hope you can see what I'm trying to do here.
Points And Lines And Triangles, Oh My!

2D version of an octahedral worldmap
An Octahedron, sort of! Baby steps... randomly coloring each triangle as I go along. I want to give each pt a height, instead, and average the corner heights for each triangle as I subdivide the triangles by edges I will add new midpts between endpts and average the endpt heights plus a little randomness. If the heights is above 0.71, the triangle is green for land, else blue for sea.

Silly World Map!
2D World Map
For now, I am randomly drawing blue or green rectangles. I can fill an array with 'green' or 'blue' for each pixel/ terrain block. Instead, I could create an array of heights at different pts on a sphere, make quads or quad pairs of triangles and worry about making rows of similar area triangles later. Baby steps...

First subdivison, pushing the center of the base triangle out
Black box full of stars, within which I want to set my world spinning! For now an orange is flying at you... Made a tetra and then pushed out the center of the base triangle. I need to be able to check new triangle to see if it's wound correctly/facing out? If the center z is negative, then cross product component z also should be, I think...
Success! But clunky...
Black box full of stars, within which I want to set my world spinning! For now an orange is flying at you... I'm drawing four edges between the four vertices of a tetra. The base of the tetra is closer to the observer and needs to have a clockwise winding, then the other three are counter-cw so I can *not* draw triangle faces which face away.

Alright, this doesn't work either...

My 1.6 gigasecond
Not So Random Date
- This is my 1.6 gigasecond. I need to do something, if only to take myself to the Golden Rooster!
