ctl(1): "Y",range=(0,255),val=100	
ctl(2): "Radius",range=(0,128),val=64

ForEveryTile:
{

	int Draw;

	for (y=y_start; y<y_end; y++){
		updateProgress(y,y_end);
	for (x=x_start; x<x_end; x++){ 

		Draw= bTriangle (x,y,ctl(0),ctl(1),ctl(2));

	for (z=0; z<Z; z++){ 

		if (Draw) pset(x,y,z,255);

	}}}
