Function Documentation

render_polygon()

void render_polygon	(	int	n,
		const Vec2	vertex[],
		int	ch = -1
	)

render a polygon with n vertices

• the polygon can be self-intersecting
• the polygon is transformed with the actual transformation matrix
• the transformation matrix can be modified via:
  • translate, rotate & scale
  • push & pop

render_triangle()

void render_triangle	(	const Vec2 &	v1,
		const Vec2 &	v2,
		const Vec2 &	v3,
		int	ch = -1
	)

render a triangle with 3 vertices
