Member Function Documentation

- (void) drawRect:

(NSRect)

dirtyRect

[implementation]

The redraw method.

Performs the 3 rendering types:

• Arrows
• Streamlines
• Color Coding.

- (void) initiateRedraw:

(NSNotification *)

notification

Calling this method will initiate a redraw of this openGL context.

This method is ment to be called via a notification center.

- (void) prepareOpenGL

[implementation]

Used to prepare the openGL context.

This method loads and compiles the shaders, creates the front and back color texture, creates a noise texture and performs all necessary initialization steps.

- (void) updateTransferfunction:

(NSNotification*)

notification

This method is invoked, if there is a need to update the Transferfunction.

This method is ment to be called via a notification center. It listens for "TransferFunction:fullRedraw".

- (Matrix4x4*) camera [protected]

The current camera Matrix4x4.

- (GLuint) shaderProgram [protected]

The id of the shader program.

---

Property Documentation

- (NSArray *) channels [read, write, retain]
