Parameters:

project - the projection to use.

draw

public void draw(Graphics2D g,
                 AffineTransform normal2Device)

Description copied from interface: Renderer

Tell the renderer to draw itself. The Graphics2D object has its AffineTransform set to transform World coordinates to display coordinates. Typically the Renderer does its drawing in World coordinates, and does not modify the AffineTransform. If the Renderer wants to draw in constant-pixel coordinates, so that its objects do not change as the user zooms in and out, use the pixelAT transform, which transforms "Normalized Device" coordinates (screen pixels) to Device coordinates. The Graphics2D object also has its clipping rectangle set (in World coordinates), which the Renderer may use for optimization. The Graphics2D object has default color and line width set; the Renderer should restore any changes it makes.

Specified by:

draw in interface Renderer

Parameters:

g - the Graphics context

normal2Device - transforms "Normalized Device" to Device coordinates. When drawing to the screen, this will be the identity transform. For other devices like printers, it is not the Identity transform. Renderers should use "Normalized Device" coordinates if they want to render non-scalable objects. Basically, you pretend you are working in screen pixels.
