public class SoHeightFieldProperty extends SoVolumeData
Height field property node.SoHeightFieldProperty
defines a set of values on a uniform grid in the XY plane that can be used to color anSoHeightFieldGeometry
when rendered using anSoHeightFieldRender
node.SoHeightFieldProperty
is derived fromSoVolumeData
and serves a similar purpose in the scene graph, providing a reference to an LDM data set which will be loaded as needed by rendering nodes, specificallySoHeightFieldRender
in this case.The property data is given using the inherited field
fileName
or by using a custom reader through thesetReader
method.Multiple
SoHeightFieldProperty
nodes can be inserted in a scene graph and combined together in the GPU to do render compositing. However the default fragment shader only handles one property (the first one). To combine multiple properties use a custom shader program (seeSoVolumeShader
and the example program).Note that it is not necessary (or useful) to set the inherited extent field.
SoHeightFieldRender
will use the extent associated with theSoHeightFieldGeometry
node.Also note that the inherited undefinedValue field is ignored. Setting it has no effect.
