Examples with DoubleInterval maspack.util.DoubleInterval used on opensource projects

Example 1 with DoubleInterval

use of maspack.util.DoubleInterval in project artisynth_core by artisynth.

the class FemBeamColored method prerender.

@Override

Example 2 with DoubleInterval

use of maspack.util.DoubleInterval in project artisynth_core by artisynth.

the class HueColorMap method setHueRange.

/**
 * Sets the hue range.  Normally, these values are in the range
 * [0, 1]; however, the hues support wrapping.  If maxHue is less
 * than minHue, colors will be interpolated backwards.
 * <p>
 * Examples:<br>
 * [0, 1/6] will interpolate from red to yellow <br>
 * [1/6, 0] will interpolate from yellow to red <br>
 * [5/6, 7/6] will interpolate from violet to yellow <br>
