Interface Triangler

All Known Implementing Classes:
DDATriangler, IntBresenhamTriangler
public interface Triangler
An interface for triangle rasterizers.

Accepts a Triangle as the shape to draw and Filler to get the colors for individual pixels.

The library contains some implementations in the same package.

Example usage: 


 final Canvas canvas; // javafx canvas to render on

 final Triangler triangler = new DDATriangler(canvas.getGraphicsContext2D());
 triangler.setFiller(new MonotoneTriangleFiller(HTMLColorf.RED));
 // any implementation can be used

 final Triangle triangle = new Polygon3(
         new Point2f(0, 1),
         new Point2f(1, 0),
         new Point2f(1, 1));

 triangler.draw(triangle);
