Making Triangles

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...

Ugh!

Still not there yet...

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.

Better Clouds and Sky!

Hopefully this really looks better...

Venus Cloud Habitat!

I want to draw some clouds and do an animation.

Eyeball World!

Tidally locked world with varying farside icecap.

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).
