Feedback node, rendering a one dimensional signal as a line

Inheritance:

Public Fields
SoSFFloat complexity: Old stuff, out of date.
SoSFTime future: Old stuff, out of date.
SoSFTime past: Old stuff, out of date.

Public Methods
virtual SbBool affectsState(): Becasue it is a feedback node, it does not affect the state of an action!
static void initClass(): Makes this class known to the OpenInventor type system. static void initClass();
tsLine(): Constructor

Action behaviour:

virtual void GLRender(SoGLRenderAction *action): This implements the GL rendering action.
void GLRenderRegular(tsData1RFloat* dataNode, GLenum GLMode, float timeNow, int startIdx, int endIdx): Called from GLRender(), renders regular sampled signal data (tsData1RFloat, ...).
void GLRenderNonregular(tsData1NFloat* dataNode, GLenum GLMode, float timeNow, int startIdx, int endIdx): Called from GLRender(), renders irregular sampled signal data (tsData1NFloat, ...).
virtual void generatePrimitives(SoAction *action): Produces primitive representation for picking.
virtual void computeBBox(SoAction *action, SbBox3f &box, SbVec3f &center): Computes the bounding box and center of a shape

Private Methods
void _computeIndices(float time, float past, float future, tsDataBase* dataNode, int& startIdx, int& endIdx): Computes the time axis indices (startIdx, endIdx) for windowed drawing between -past and +future
SO_NODE_HEADER(tsLine): Inventor macro
virtual ~tsLine(): Destructor

Documentation

Feedback node, rendering a one dimensional signal as a line. Time is mapped to the X-axis, signal values (spectra: amplitude) to Y-axis.
Takes time to render for from tsTimeElement. Takes signal data from a tsData2Element, normal vectors from a tsNormalElement. Material and draw style is standard. Texture mapping is not yet implemented!
