◆ isInstanceType()

bool isInstanceType ( )

Returns true if this group is an instance type node; i.e.

it begins the root of a local coordinate space. This is not related to instancing (multiple copies of a node in a scene graph).

This also includes the case of the node including a billboard flag without an explicit center, which implicitly makes the node behave like an instance.

◆ isJoint()

bool isJoint ( )

Returns true if this particular node represents a <Joint> entry or not.

This is a handy thing to know since Joints are sorted to the end of their sibling list when writing an egg file. See EggGroupNode::write().

◆ modifyDefaultPose()

EggTransform modifyDefaultPose ( )

Returns a writable accessor to the initial pose transform.

This is the <DefaultPose> entry for a Joint, and defines only the initial transform pose for the unanimated joint; it has nothing to do with the group's <Transform> entry, which defines the (eventual) space of the group's vertices.

refVertex ( EggVertex  vert,
double  membership

Removes the first instance of the indicated object type from the group if it is present.

Returns true if the object type was found and removed, false otherwise.

◆ setBillboardCenter()

setBillboardCenter ( const LPoint3d  billboard_center)

Sets the point around which the billboard will rotate, if this node contains a billboard specification.

If a billboard type is given but no billboard_center is specified, then the group node is treated as an <Instance>, and the billboard rotates around the origin. If, however, a billboard_center is specified, then the group node is not treated as an <Instance>, and the billboard rotates around the specified point.

The point is in the same coordinate system as the vertices of this node: usually global, but possibly local if there is an <Instance> somewhere above. Specifically, this is the coordinate system defined by get_vertex_frame().

◆ setBillboardType()

setBillboardType ( EggGroup::BillboardType  type)

◆ setDefaultPose()

setDefaultPose ( const EggTransform  transform)

Replaces the initial pose transform.

This is the <DefaultPose> entry for a Joint, and defines only the initial transform pose for the unanimated joint; it has nothing to do with the group's <Transform> entry, which defines the (eventual) space of the group's vertices.

◆ setDirectFlag()

setDirectFlag ( bool  flag)

◆ setFromCollideMask()

setFromCollideMask ( CollideMask  mask)

◆ setGroupType()

setSwitchFps ( double  fps)

◆ setTag()

setTag ( str  key,
str  value 
)

Associates a user-defined value with a user-defined key which is stored on the node.

This value has no meaning to Panda; but it is stored indefinitely on the node until it is requested again. This value will be copied to the PandaNode that is created for this particular EggGroup if the egg file is loaded as a scene.

Each unique key stores a different string value. There is no effective limit on the number of different keys that may be stored or on the length of any one key's value.

◆ setTexlistFlag()

setTexlistFlag ( bool  flag)

◆ setVertexMembership()

setVertexMembership ( EggVertex  vert,
double  membership 
)

Explicitly sets the net membership of the indicated vertex in this group to the given value.
