Detailed Description

The Curve is a class for storing control points on a curve and evaluating the results later.


Member Function Documentation

virtual uint32_t nvidia::apex::Curve::addControlPoint ( const Vec2R controlPoint) [pure virtual]

Add a control point to the list of control points, returning the index of the new point.

virtual void nvidia::apex::Curve::addControlPoints ( ::NvParameterized::Interface param,
::NvParameterized::Handle hPoints 
) [pure virtual]

Add a control points to the list of control points. Assuming the hPoints points to a list of vec2s

virtual bool nvidia::apex::Curve::calculateControlPoints ( float  x,
Vec2R outXPoints,
Vec2R outYPoints 
) const [pure virtual]

Locates the control points that contain x, placing the resulting control points in the two out parameters. Returns true if the points were found, false otherwise. If the points were not found, the output variables are untouched

virtual uint32_t nvidia::apex::Curve::calculateFollowingControlPoint ( float  xValue) const [pure virtual]

Locates the first control point with x larger than xValue or the nimber of control points if such point doesn't exist

virtual float nvidia::apex::Curve::evaluate ( float  x) const [pure virtual]

Retrieve the output Y for the specified input x, based on the properties of the stored curve described by mControlPoints.
