I finally have the land blob area derived from the
cross product! 8-P
I have the page looking at the fan area size and
comparing this to real world continent areas.
Tonight I just want to start building a second triangle
fan. I already have randomly found a point index in the
land plob shape. I need to know the preceding and the
following point to get an angle and derive a new center
point halfway around an arc between those two...
World circumference is 40499.6 km and div size is 405px, and world area is 522.09 m. km^2
(area of the triangles from cross product)
Land blob area: 13.7 m. km^2, 2.62%
Between Australia and South America in size
Shape: polygon(62.7% 39.9%, 57% 41.4%, 53.9% 37.1%, 54.3% 33%, 58.3% 33.4%, 59.4% 29.2%, 63.6% 30%, 65.6% 32.5%)
9 vertices, first pt: 5, previous: 4, next: 6, first angle: 2.23 , 2nd: -0.43, total: -2.66, halfway angle: 0.89
