|
|
* Create a polygon of any shape and varying elevations from the edges towards the center.
|
351 |
d456b075
|
Leszek Koltunski
|
* Optionally make it more dense at the vertices.
|
352 |
808ef3aa

Leszek Koltunski
|
*
|
353 |
|
|
* @param verticesXY 2N floats - packed description of polygon vertices. N pairs (x,y).
|
354 |
8b082b9f
|
Leszek Koltunski
|
* Vertices HAVE TO be specified in a COUNTERCLOCKWISE order (starting from any).
|
355 |
808ef3aa
|
Leszek Koltunski
|
* @param bands 2K floats; K pairs of two floats each describing a single band.
|
356 |
|
|
* From (1.0,Z[0]) (outer edge, its Z elevation) to (0.0,Z[K]) (the center,
|
357 |
|
|
* its elevation). The polygon is split into such concentric bands.
|
358 |
ac6a08e7
|
Leszek Koltunski
|
* Must be band[2*i] > band[2*(i+1)] !
|
359 |
b2913a86
|
Leszek Koltunski
|
* @param edgeUp N booleans - one for each edge; the first connects vertices (0,1) and (2,3);
|
360 |
|
|
* then just like 'verticesXY', i.e. counterclockwise.
|
361 |
|
|
* If this is null, all edges are by default 'down'.
|
362 |
|
|
* 'Down' means that edge's Z is equal to 0; 'up' means that its Z, at least in its
|
363 |
|
|
* middle, is equal to the highest elevation in the middle of the mesh.
|
364 |
|
|
* If the 'previous' edge is also up, then the Z is up horizontally from its middle
|
365 |
|
|
* to the left vertex; else it goes down along the same function it goes along the bands.
|
366 |
|
|
* Same with the right half of the edge.
|
367 |
d456b075
|
Leszek Koltunski
|
* @param exIndex This and the next parameter describe how to make the mesh denser at the
|
368 |
|
|
* polyVertices. If e.g. exIndex=3 and exVertices=2, then 3 triangles of the
|
369 |
f4a2d97e
|
Leszek Koltunski
|
* outermost band (and 2 triangles of the next band, and 1 triangle of the third
|
370 |
d456b075
|
Leszek Koltunski
|
* band) get denser - the 3 triangles become 3+2 = 5.
|
371 |
|
|
* @param exVertices See above.
|
372 |
0b732630
|
Leszek Koltunski
|
* @param centerX the X coordinate of the 'center' of the Polygon, i.e. point of the mesh
|
373 |
|
|
* all bands go to.
|
374 |
|
|
* @param centerY Y coordinate of the center.
