Example 1 with Interpolation

use of com.sk89q.worldedit.math.interpolation.Interpolation in project FastAsyncWorldEdit by IntellectualSites.

the class EditSession method drawSpline.

/**
 * Draws a spline (out of blocks) between specified vectors.
 *
 * @param pattern     The block pattern used to draw the spline.
 * @param nodevectors The list of vectors to draw through.
 * @param tension     The tension of every node.
 * @param bias        The bias of every node.
 * @param continuity  The continuity of every node.
 * @param quality     The quality of the spline. Must be greater than 0.
 * @param radius      The radius (thickness) of the spline.
 * @param filled      If false, only a shell will be generated.
 * @return number of blocks affected
 * @throws MaxChangedBlocksException thrown if too many blocks are changed
