com.trapezium.vrmlspace
Class SpaceStructureLoader  

java.lang.Object
  com.trapezium.vrmlspace.SpaceStructureLoader

---

public class SpaceStructureLoader

extends java.lang.Object

The SpaceStructureLoader manages a set of SpaceStructures associated with IndexedFaceSets in a file. Two sets of SpaceStructures are kept -- one for each IFS in the file, accessed by index, and one for each Coordinate node in the file, accessed by coord node. These lists will be different if the file uses DEF/USE of Coordinate nodes.

Since:

1.0

Version:

1.0, 8 Oct 1998

Method Detail

setDataSource

void setDataSource(com.trapezium.vrml.node.Node n)

---

getSpaceStructure

public com.trapezium.space.SpaceStructure getSpaceStructure(int offset)

Access space structure by offset.

---

getSpaceStructure

public com.trapezium.space.SpaceStructure getSpaceStructure(com.trapezium.vrml.node.Node coordNode)

Access space structure by coord node.

---

loadSpaceStructure

public com.trapezium.space.SpaceStructure loadSpaceStructure(com.trapezium.vrml.node.Node n)

Load a SpaceStructuare, save it in the independentStructures and completeStructures list. If the Coordinate node is used, then the existing entry from the completeStructures list is used, and the faces for the current SpaceStructure are appended onto that entry, resulting in that entry being a union of all SpaceStructures associated with a particular coordinate node.

                  com.trapezium.vrml.fields.Field f2,
                  com.trapezium.vrml.fields.Field f3,
                  com.trapezium.vrml.fields.Field f4)

Check if any of the fields refer to a DEFUSEnode

hasDEFUSE

boolean hasDEFUSE(com.trapezium.vrml.fields.Field f)

Check if field refers to a DEFUSENode

---

load3f

void load3f(com.trapezium.vrml.VrmlElement valueNode,
            com.trapezium.space.SpaceEntitySet target)

Load the vertices into a SpaceStructure.

---

load2f

void load2f(com.trapezium.vrml.VrmlElement valueNode,
            com.trapezium.space.SpaceEntitySet target)

Load the texCoords into a SpaceStructure.

---

loadIlist

void loadIlist(com.trapezium.vrml.VrmlElement ilist,
               com.trapezium.space.SpaceEntitySet target1,
               com.trapezium.space.SpaceEntitySet target2)

Load the index array into a SpaceStructure.
