|
||
|
|
Class that takes care of tessellation of polygons into triangles.
|
||
|
|
|
||
|
|
It is expected that client code will create the tessellator object, then repeatedly call
|
||
|
|
addPolygon() method that will generate triangles, and finally call data() to get final vertex data.
|
||
|
|
|
||
|
|
Optionally provides extrusion by adding triangles that serve as walls when extrusion height is non-zero.
