Functions

func DrawFace

func DrawFace(f *dcel.Face)

DrawFace converts a face into a polygon, then draws it as a polygon.

func DrawLine

func DrawLine(p1, p2 geom.D2)

DrawLine sends a line instruction to the Visual Channel

func DrawPoly

func DrawPoly(ps []physics.Vector)

DrawPoly sends a polygon made up of ps (assumed convex) to the visual channel

func DrawVerticalLine

func DrawVerticalLine(p geom.D2)

DrawVerticalLine sends a line extending through the screen vertically to the visual channel at a given point

Types

type Visual

type Visual struct {
	render.Renderable
	Layer int
}

Visual is a renderable with attached instructions to be given to a renderable at time of drawing.
