const String | name |
A base class for things that may be directly added into the egg hierarchy.
This includes groups, joints, polygons, vertex pools, etc., but does not include things like vertices.
object __reduce__ | ( | ) |
applyTexmats | ( | ) |
Applies the texture matrices to the UV's of the vertices that reference them, and then removes the texture matrices from the textures themselves.
EggRenderMode determineAlphaMode | ( | ) |
Walks back up the hierarchy, looking for an EggGroup or EggPrimitive or some such object at this level or above this node that has an alpha_mode other than AM_unspecified.
Returns a valid EggRenderMode pointer if one is found, or NULL otherwise.
EggRenderMode determineBin | ( | ) |
Walks back up the hierarchy, looking for an EggGroup or EggPrimitive or some such object at this level or above this node that has a bin specified.
Returns a valid EggRenderMode pointer if one is found, or NULL otherwise.
bool determineDecal | ( | ) |
Walks back up the hierarchy, looking for an EggGroup at this level or above that has the "decal" flag set.
Returns the value of the decal flag if it is found, or false if it is not.
In other words, returns true if the "decal" flag is in effect for the indicated node, false otherwise.
EggRenderMode determineDepthOffset | ( | ) |
Walks back up the hierarchy, looking for an EggGroup or EggPrimitive or some such object at this level or above this node that has a depth_offset specified.
Returns a valid EggRenderMode pointer if one is found, or NULL otherwise.

Walks back up the hierarchy, looking for an EggGroup or EggPrimitive or some such object at this level or above this node that has a draw_order specified.
Returns a valid EggRenderMode pointer if one is found, or NULL otherwise.
bool determineIndexed | ( | ) |
Walks back up the hierarchy, looking for an EggGroup at this level or above that has the "indexed" scalar set.
Returns the value of the indexed scalar if it is found, or false if it is not.
In other words, returns true if the "indexed" flag is in effect for the indicated node, false otherwise.
EggRenderMode determineVisibilityMode | ( | ) |
Walks back up the hierarchy, looking for an EggGroup or EggPrimitive or some such object at this level or above this node that has a visibility_mode other than VM_unspecified.
Returns a valid EggRenderMode pointer if one is found, or NULL otherwise.
flattenTransforms | ( | ) |
Removes any transform and instance records from this node in the scene graph and below.
If an instance node is encountered, removes the instance and applies the transform to its vertices, duplicating vertices if necessary.
Since this function may result in duplicated vertices, it may be a good idea to call remove_unused_vertices() after calling this.

int getDepth | ( | ) |
Returns the number of nodes above this node in the egg hierarchy.
const LMatrix4d getNodeFrame | ( | ) |
Returns the coordinate frame of the node itself.
This is simply the net product of all transformations up to the root.
const LMatrix4d getNodeFrameInv | ( | ) |
Returns the inverse of the matrix returned by get_node_frame().
See get_node_frame().
const LMatrix4d getNodeFrameInvPtr | ( | ) |

const LMatrix4d getNodeFramePtr | ( | ) |
Returns either a NULL pointer or a unique pointer shared by nodes with the same get_node_frame() matrix.
const LMatrix4d getNodeToVertex | ( | ) |
Returns the transformation matrix suitable for converting vertices in the coordinate space of the node to the appropriate coordinate space for storing in the egg file.
This is the same thing as:
get_node_frame() * get_vertex_frame_inv()
const LMatrix4d getNodeToVertexPtr | ( | ) |
Returns either a NULL pointer or a unique pointer shared by nodes with the same get_node_to_vertex() matrix.
EggGroupNode getParent | ( | ) |
const LMatrix4d getVertexFrame | ( | ) |
Returns the coordinate frame of the vertices referenced by primitives at or under this node.
This is not the same as get_node_frame().
Generally, vertices in an egg file are stored in the global coordinate space, regardless of the transforms defined at each node. Thus, get_vertex_frame() will usually return the identity transform (global coordinate space). However, primitives under an <Instance> entry reference their vertices in the coordinate system under effect at the time of the <Instance>. Thus, nodes under an <Instance> entry may return this non- identity matrix.
Specifically, this may return a non-identity matrix only if is_local_coord() is true.
const LMatrix4d getVertexFrameInv | ( | ) |
Returns the inverse of the matrix returned by get_vertex_frame().
See get_vertex_frame().
const LMatrix4d getVertexFrameInvPtr | ( | ) |

const LMatrix4d getVertexFramePtr | ( | ) |
Returns either a NULL pointer or a unique pointer shared by nodes with the same get_vertex_frame() matrix.
const LMatrix4d getVertexToNode | ( | ) |
Returns the transformation matrix suitable for converting the vertices as read from the egg file into the coordinate space of the node.
This is the same thing as:
get_vertex_frame() * get_node_frame_inv()
const LMatrix4d getVertexToNodePtr | ( | ) |
Returns either a NULL pointer or a unique pointer shared by nodes with the same get_vertex_to_node() matrix.
bool isAnimMatrix | ( | ) |
Returns true if this node represents a table of animation transformation data, false otherwise.
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().
bool isLocalCoord | ( | ) |
Returns true if this node's vertices are not in the global coordinate space.
This will be the case if there was an <Instance> node under a transform at or above this node.
bool isUnderInstance | ( | ) |
Returns true if there is an <Instance> node somewhere in the egg tree at or above this node, false otherwise.

Parses the egg syntax given in the indicate string as if it had been read from the egg file within this object's definition.
