Inherited By : DzVertexMesh

The base class for all mesh and geometry objects that can be referenced by DzShape, passed through the geometry pipeline, and drawn in the 3d view.

Boolean : hasPendingChanges

Holds whether or not this geometry has pending changes.

Since:

• 4.9.2.8

DzGeometry : getCurrentGeometryForNode( DzNode node )

Parameter(s):

• node - The node to get the geometry from.

Return Value:

• The current geometry for node, or NULL if node has no geometry associated with it.

Since:

• 4.9.3.57

void : beginEdit( Boolean enableUndo=true )

Parameter(s):

• enableUndo - If true, operations performed on the geometry after this call will be undoable.

Begin an edit operation on the geometry. Most meshes will require that this function is called before any topology change (i.e., adding/removing vertices, polygons, etc).

Attention:

• Must call finishEdit() or cancelEdit() before calling beginEdit() again.

void : cancelEdit()

Cancel the current edit operation on the geometry.

Boolean : copyFrom( DzVertexMesh mesh, Boolean shareVerts=false, Boolean shareFacets=true )

Parameter(s):

• mesh - The vertex mesh to make this a copy of.
• shareVerts - If true, the vertex list will be shared between the given mesh and this mesh. If false, the vertex list will be a deep copy.
• shareFacets - If true, the facet set will be shared between the given mesh and this mesh. If false, the facet set will be a deep copy.

Return Value:

• true if this geometry is a copy of mesh (either already or as a result of this operation), otherwise false.

Since:

• 4.9.3.57

void : finishEdit()

Finish the current edit operation on the geometry.

DzBox3 : getBoundingBox()

DzBox3 : getGroupBoundingBox( String groupName )

Parameter(s):

• groupName - The name of the group to get the bounding box for.

Return Value:

• transform - The transform to apply to the box.
• pos - The position to apply to the box.
• rot - The rotation to apply to the box.
• scale - The scale to apply to the box.

• pos - The position to apply to the box.
• rot - The rotation to apply to the box.
• scale - The scale to apply to the box.

Return Value:

• An oriented box encompassing all geometry in the group named groupName (if any), transformed according to pos, rot and scale.

• A local space bounding box for this geometry.

Parameter(s):

• pos - The position to apply to the box.
• rot - The rotation to apply to the box.
• scale - The scale to apply to the box.

Return Value:

• A unique identifier for this geometry.

DzMap : getUVs()

Return Value:

• The active UV set for this geometry.

DzUVSet : getUVSet( Number which )

Parameter(s):

• which - The index of the UV set to get; must be in the [0, getNumUVSets() - 1] range.

Return Value:

• The UV set at the specified index (if any), otherwise null.

Boolean : isEmpty()

Return Value:

• true if the geometry is empty, otherwise false.

Boolean : isRuntimeGenerated()
