Animate making triangles from a point cloud. First, generate a point cloud, then make sure the points don't overlap nor are too close. Make the initial triangle by finding three points which are close together, a point picked at random, a second point which is closest to that first point and a third point which is closest to the midpoint of the first two endpoints. A triangle will be defined as three points, three edges and an area, and an edge will be defined as two endpoints and a midpoint. So I find two points, make an edge, find a third point and make a triangle and two more edges... and I'm writing a novel here! 8-P

Finally!
A procedurally and pseudo randomly generated star system, with one star and one world and map. This is a coin model, with the two hemispheres repreenting the two faces, heads or tails, of a coin. We're interested in the pixels of the near and the far hemispheres here. (Sorry, it takes a few seconds! 8-P)

G'night..
A procedurally and pseudo randomly generated star system, with one star and one world and map. This is a square 'postage-stamp' rectangle version of the world. Each grid point of this world map has UV coordinates for a pixel in the square map and the corresponding XYZ coordinates for a bit of the spherical world map. We're generating feature points from the grid to find voronoi regions which are either land or sea for a simple map, heights but not concerned about surface temps or biomes, not yet.
Still getting something very wrong...

Better Four Leaf Clover!
Click inside of the blue hemisphere to make a four leaf clover and hit the 'click to generate another' to clear and draw a new world. I'm done with this for now, although I don't have the 4LC drawing to the surface, yet...

Four Leaf Clovers
I have the page draw a circle for the hemisphere we can see, a grid of points within the radius, all at a random location inside of the black box. I want to draw the four leaf clover to the surface of the world, but for tonight I just drew some green circles for leaves and orange lines for stems. You click inside of the blue hemisphere to make a four leaf clover and hit the 'click to generate another' to clear and draw a new world.

Pi from points inside of a sphere
I want to count the points within a sphere to get the volume and then derive pi. Pick a point in the blue box and wait a few seconds while the page chugs along through about a million grid points... Then I figured out how to speed this up, LOL!
Pi from random points in a circle
Pick a center point in the blue box and the page calclates pi from the portion of ten thousand random points which are within the circle.

Venus Cloud Habitat!
I want to draw some clouds and do an animation.

Octasphere with Voronoi Regions
I want to use feature pts to sort the triangles to voronoi regions and assign them to be land or sea (now with cold regions).
