com.openinventor.volumeviz.details.SoHeightFieldDetail

public class SoHeightFieldDetail
extends SoDetail

Stores detail information about a picked cell in a heightfield. A successful pick operation returns an SoPickedPoint object. If the picked geometry is an SoHeightFieldRender node, use the getDetail method and cast the result to this class to get extra information about the the pick.

SoHeightFieldDetail returns

• The i,j,k position of the picked cell (position in data space).
• The value of the picked cell retrieved from the current SoHeightFieldProperty
• or the values of the picked cell when multiple SoHeightFieldProperty nodes are inherited.
• The data set of the picked heightfield, i.e., the current SoHeightFieldProperty node.
• or the data sets of the picked heightfield, when multiple SoHeightFieldProperty nodes are inherited.
