This class takes 4 key frames as its input (using TCBKeyFrame). If interpolating between the i<sup>th</sup> and (i+1)<sup>th</sup> key frame then the four key frames that need to be specified are the (i-1)<sup>th</sup>, i<sup>th</sup>, (i+1)<sup>th</sup> and (i+2)<sup>th</sup> keyframes in order. The CubicSegmentClass then pre-computes the hermite interpolation basis coefficients if the (i+1)<sup>th</sup> frame has the linear flag set to zero. These are used to calculate the interpolated position, scale and quaternions when they requested by the user using the getInterpolated* methods. If the the (i+1)<sup>th</sup> frame's linear flag is set to 1 then the class uses linear interpolation to calculate the interpolated position, sccale and quaternions it returns through the getInterpolated* methods.<P><P><DL><DT><B>Since:</B><DD>Java3D 1.1</DD></DD></DL><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><!-- ======== CONSTRUCTOR SUMMARY ======== --><!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Method Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> float</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../../com/sun/j3d/utils/behaviors/interpolators/CubicSplineSegment.html#computeLength(float)">computeLength</A></B>(float u)</CODE><BR> Computes the length of the curve at a given point between key frames.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../../com/sun/j3d/utils/behaviors/interpolators/CubicSplineSegment.html#getInterpolatedPosition(float, javax.vecmath.Point3f)">getInterpolatedPosition</A></B>(float u, <A HREF="../../../../../../javax/vecmath/Point3f.html">Point3f</A> newPos)</CODE><BR> Computes the interpolated position along the curve at a given point between key frames and returns a Point3f with the interpolated x, y, and z scale components.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../../com/sun/j3d/utils/behaviors/interpolators/CubicSplineSegment.html#getInterpolatedPositionVector(float, javax.vecmath.Vector3f)">getInterpolatedPositionVector</A></B>(float u, <A HREF="../../../../../../javax/vecmath/Vector3f.html">Vector3f</A> newPos)</CODE><BR> Computes the interpolated position along the curve at a given point between key frames and returns a Vector3f with the interpolated x, y, and z scale components.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../../com/sun/j3d/utils/behaviors/interpolators/CubicSplineSegment.html#getInterpolatedQuaternion(float, javax.vecmath.Quat4f)">getInterpolatedQuaternion</A></B>(float u, <A HREF="../../../../../../javax/vecmath/Quat4f.html">Quat4f</A> newQuat)</CODE><BR> Computes the interpolated quaternion along the curve at a given point between key frames.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../../com/sun/j3d/utils/behaviors/interpolators/CubicSplineSegment.html#getInterpolatedScale(float, javax.vecmath.Point3f)">getInterpolatedScale</A></B>(float u, <A HREF="../../../../../../javax/vecmath/Point3f.html">Point3f</A> newScale)</CODE><BR> Computes the interpolated scale along the curve at a given point between key frames and returns a Point3f with the interpolated x, y, and z scale components.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> float</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../../com/sun/j3d/utils/behaviors/interpolators/CubicSplineSegment.html#getInterpolatedValue(float)">getInterpolatedValue</A></B>(float u)</CODE><BR> Computes the ratio of the length of the spline from the i<sup>th</sup> key frame to the position specified by u to the length of the entire spline segment from the i<sup>th</sup> key frame to the (i+1) <sup>th</sup> key frame.</TD></TR>⌨️ 快捷键说明
