Derive fourth coordinate from three points of user defined triangle

Pick three points to make a triangle

Oops!

Fill up a map rectangle with triangle fans of land and sea.

Find the 10 px quads partially within the circle

Pick a point and generate the planet, mass first.

Oops!

 So, haven't written...

Been a long week already, gotta work Saturday 

Finally

Back to finding quads within a circle to make a stupid polyhedron. Project a grid of quads 10 px or a thousand kilometers on a side. The edge quads are bigger, taller. The quads are subdivided into two triangles along and edge between the nearest corners.

stuff

Pick a point and generate the planet, mass first.

Oops!

There once was a silly old fool...

Who made world maps, of course.

Mass derived world generation

Pick a point and generate the planet, mass first.

Oops!

Get something done tonight!

Go at the world building in a different way, starting with mass, deriving planetary radius from mass and density.

Tetra to poor Vinnies 24-sided polyhedron

Pick three points to make a triangle

Oops!

I need to write again, and specifically work up settings and scenarios. I can do my version of Traveller with percentiles.

I'n going to input some coordinates with which to build a world based on an initial triangle from the three vertices the user selects.

I can modify this triangle into a pentagon, and the pentagon into a fan of five triangles, and then build out a ring of triangles in a strip more or less around the equator, then another triangle fan around the other pole of the globe.

I have a page which takes three points from me and draws a triangle. When you click again it subdivides the triangle into a pentagon.

Make a tetrahedron from a triangle

Pick three points to make a triangle

Oops!

 They murdered a man on the streets of Minneapolis today. May they rot in hell...

strips of diamonds?

Make rows of triangle strips.

Oops!

Radius

Change to an 'exploded' icosahedron.

Oops!

strip it down

Do something...

Oops!

Something weird, something wonderful.

Spreading out...

The horde emptying the city?

Maps. Need to make some maps...

The simplest thing is to build a icosahedron and subdivide each of twenty triangles.

Or build out around points on a globe mapped to a 2D version of the globe  

Russia murdered some pensioner's in one air attack; they were heading to get their pensions.

 Build rows of diamonds 

I keep trying to keep up...

Some code

Make rows of triangle strips.

Oops!

She played herself.

Write something kewl...

What the heck is going on in this YT story?

Fill a canvas with light brown to match the blog background and a 52 by 52 grid of 10 pixel quads.

Use displacement to move the points in the grid around, then subdivide quads into triangle pairs based on closest diagonal corners.

A Carrington Event followed by an AI takeover?

Yeah, didn't accomplish much this weekend, either...

Something weird, something wonderful...

Rows of quads

Make rows of triangle strips.

Oops!

Stuff happens...

Build a grid of quads, subdivide into triangle pairs.

points to triangles

Just splat out a point

Oops!

To Home?

Pick a point, do some math, draw a point with the coordinates

The technical details

Fill up points and build triangles and daughter quads or triangles.
