void Snake.DisplayImagePlane ( bool display )

Renders the snake image plane.

Parameters

[in] display true if it should be rendered

Definition at line 133 of file Snake.cs.

Vector3 [] Snake.GetSnakeWorldPoints ( )

Gets the resulting contour in world coordinates.

Returns: an array of vectors

Transforms the resulting contour to world points and returns them.

Definition at line 65 of file Snake.cs.

Vector3 [] Snake.GetStartWorldPoints ( )

Gets the start contour in world coordinates.

Returns: an array of vectors

Transforms the start contour to world points and returns them.

Definition at line 82 of file Snake.cs.

void Snake.InitSnake ( bool expanding = false )

Initializes the snake with the given contour.

Parameters

[in] expanding if the snake is expanding or contracting

calculates the internal energie of the snake and saves it in a matrix representation.

Definition at line 300 of file Snake.cs.

void Snake.SetControlPoints ( Vector3[] controlPoints )

Sets the contour.

Parameters

[in] controlPoints an array of points in world coordinates in the correct order for the contour

Transforms the control points to screen coordinates an sets them as the snake contour

Definition at line 101 of file Snake.cs.

void Snake.ShowContour ( )

Renders the current contour state on the image plane.

Definition at line 140 of file Snake.cs.

void Snake.UpdateSnake	(	int	iterations,
		bool	drawSteps
	)

Executes the snake algorithm.

Parameters

[in]	iterations	the number of iterations
[in]	drawSteps	if the contour steps should be drawn

Calculates the extern snake energie term and applies the weighted extern and intern energie to the coordinates
