concave polys broken in P3D and OGL
May 22nd, 2005, 11:47am  
Code:

void setup()
{
  size(500,500,P3D);
}
void draw()
{
  background(0);
  beginShape(POLYGON); 
  vertex(230, 220); 
  bezierVertex(280, 200, mouseX, mouseY, 230, 275); 
  bezierVertex(250, 280, 260, 225, 230, 220); 
  endShape(); 
}


Looks like it's broken again.

Works fine with just size(500,500), but not with P3D or OpenGL.

there are just problems when points are duplicated. like when the last point in the shape meets the first, which happens with curves and i need to re-add detection code to avoid it.

you may have some luck (no guarantees) with making the second bezierVertex() call not meet the vertex() coordinate exactly, like just have it off by .0001 or something till it can be fixed.
