Definition at line 745 of file eggGroup.I.

◆ is_instance_type()

bool EggGroup::is_instance_type ( ) const

inline

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.

Definition at line 32 of file eggGroup.I.

◆ is_joint()

bool EggGroup::is_joint ( ) const

virtual

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().

Reimplemented from EggNode.

Definition at line 468 of file eggGroup.cxx.

◆ modify_default_pose()

EggTransform & EggGroup::modify_default_pose ( )

inline

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.

Definition at line 780 of file eggGroup.I.

◆ ref_vertex()

void EggGroup::ref_vertex	(	EggVertex *	vert,
		double	membership = `1.0`
	)

Adds the vertex to the set of those referenced by the group, at the indicated membership level.

If the vertex is already being referenced, increases the membership amount by the indicated amount.

Definition at line 608 of file eggGroup.cxx.

References unref_vertex().

Referenced by DaeCharacter::influence_vertex(), and split_vertex().

◆ remove_group_ref()

void EggGroup::remove_group_ref ( int n )

Removes the nth <Ref> entry within this group.

See add_group_ref().

Definition at line 787 of file eggGroup.cxx.

◆ remove_object_type()

bool EggGroup::remove_object_type ( const std::string & object_type )

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.

Definition at line 161 of file eggGroup.cxx.

◆ set_tag()

void EggGroup::set_tag	(	const std::string &	key,
		const std::string &	value
	)

inline

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.

Definition at line 720 of file eggGroup.I.

◆ set_vertex_membership()

void EggGroup::set_vertex_membership	(	EggVertex *	vert,
		double	membership
	)

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

Definition at line 692 of file eggGroup.cxx.

References unref_vertex().

◆ steal_vrefs()

void EggGroup::steal_vrefs ( EggGroup * other )

Moves all of the vertex references from the indicated other group into this one.

If a given vertex was previously shared by both groups, the relative memberships will be summed.

Definition at line 721 of file eggGroup.cxx.

◆ string_billboard_type()

EggGroup::BillboardType EggGroup::string_billboard_type ( const std::string & strval )

static

Returns the BillboardType value associated with the given string representation, or BT_none if the string does not match any known BillboardType value.

Definition at line 866 of file eggGroup.cxx.

static

Returns the BlendMode value associated with the given string representation, or BM_none if the string does not match any known BlendMode.

Definition at line 946 of file eggGroup.cxx.

static

static

Returns the CollideFlags value associated with the given string representation, or CF_none if the string does not match any known CollideFlags value.

◆ string_cs_type()

EggGroup::CollisionSolidType EggGroup::string_cs_type ( const std::string & strval )

static

Returns the CollisionSolidType value associated with the given string representation, or CST_none if the string does not match any known CollisionSolidType value.

Member Data Documentation

◆ clear_blend_color

void EggGroup::clear_blend_color

inline

Removes the blend color specification.

Definition at line 318 of file eggGroup.h.

◆ get_blend_color

const LColor & EggGroup::get_blend_color

inline

Returns the blend color if one has been specified, or (0, 0, 0, 0) if one has not.

Definition at line 318 of file eggGroup.h.

◆ get_default_pose

const EggTransform & EggGroup::get_default_pose

inline

Returns a read-only 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.

Definition at line 320 of file eggGroup.h.

◆ get_group_ref

EggGroup * EggGroup::get_group_ref

Returns the nth <Ref> entry within this group.

See add_group_ref().

Definition at line 354 of file eggGroup.h.

◆ get_num_group_refs

int EggGroup::get_num_group_refs

Returns the number of <Ref> entries within this group.

See add_group_ref().

Definition at line 354 of file eggGroup.h.

◆ has_blend_color

bool EggGroup::has_blend_color

inline

Returns true if the blend color has been specified, false otherwise.

Definition at line 318 of file eggGroup.h.

◆ set_billboard_center

void EggGroup::set_billboard_center

inline

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().

Definition at line 290 of file eggGroup.h.

◆ set_default_pose

void EggGroup::set_default_pose

inline

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.

Definition at line 320 of file eggGroup.h.

◆ set_indexed_flag

void EggGroup::set_indexed_flag

inline

If this flag is true, geometry at this node and below will be generated as indexed geometry.

Definition at line 307 of file eggGroup.h.
