Triangle to pentagon to icosa... eventually!

Asteroid!

Click on three different points in the window to define a triangle and start turning that into a lopsided pentagon, then that into a lopsided icosahedron, which is further subdivided into an asteroid. Currently I have all twelve vertices of my lopsided icosa, 0 through 11 in 'computer', and now I would like to draw all 20 triangles. The next step is to start using the mouse click to turn the icosa in 3D (or 2.5D... 8-).

Done!

Make a Happy Little Tree! 8-P

Easter Animation

Click on three different points in the window to define a triangle and start generating a happy little tree! Tonight I just have a trunk and a green puffball, but I am going to build the trunk and foliage out of triangles, a 3D model and rotate the thing around the origin.

Points in Spaaaace!

Points in Spaaaace!

Click on a point and drag left or right, up or down, to get a depth. Negative X or Y position reduces the Z-depth and positive X or Y increases the Z-depth. As the mouse moves around the canvas/window the page draws a line between the initial point and the current mouse point, with a depth value. When you release the mouse pointer we have an XYZ coordinate for a point in 3D space which we display with perspective tricks. I want to be able to pick a point in a volume and also rotate the points around the center of the volume.

Drawing a Gumdrop-shaped SSTO

Rocket Design Utility

Click and drag to draw a circle representing a spherical LOX tank in red and two more smaller aqua circles representing a toroidal liquid hydrogen tank. I'm drawing a gumdrop rocket, ideally a hydrolox SSTO... The orange box represents internal volume for rocket engines, pumps, etc.

Star System Generation, like a few dozen times before...

World Building

Running a little star system generation, making boring little solar system clones... 8-P
