Detailed Description

Corresponding to an <Xfm$Anim> entry, this stores a two-dimensional table with up to nine columns, one for each component of a transformation.

This is an older syntax of egg anim table, not often used currently--it's replaced by EggXfmSAnim.

const LMatrix4d & EggNode::get_vertex_frame (   )  const [inline, inherited]
 

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 entry reference their vertices in the coordinate system under effect at the time of the . Thus, nodes under an entry may return this non-identity matrix.

Specifically, this may return a non-identity matrix only if is_local_coord() is true.

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

Updates the object accordingly. Returns true if successful, false if there was some parse error or if the object does not support this functionality.

void EggNode::r_apply_texmats (  EggTextureCollection &  textures  )  [protected, virtual, inherited]
 

The recursive implementation of apply_texmats().

Reimplemented in EggGroupNode, EggNurbsSurface, and EggPrimitive.

void EggNode::r_flatten_transforms (   )  [protected, virtual, inherited]

void EggXfmAnimData::r_mark_coordsys (  CoordinateSystem  cs  )  [protected, virtual]
 

This is only called immediately after loading an egg file from disk, to propagate the value found in the CoordinateSystem entry (or the default Y-up coordinate system) to all nodes that care about what the coordinate system is.

Reimplemented from EggNode.

Definition at line 296 of file eggXfmAnimData.cxx.

void EggXfmAnimData::r_transform (  const LMatrix4d &  mat,
const LMatrix4d &  inv,
CoordinateSystem  to_cs
)  [protected, virtual]
 

Applies the indicated transform to all the rows of the table.

This actually forces the generation of a totally new set of rows.

Reimplemented from EggNode.

void EggNode::r_transform_vertices (  const LMatrix4d &  mat  )  [protected, virtual, inherited]
 

This is called from within the egg code by transform_vertices_only()().

It applies a transformation matrix to the current node in some sensible way (if the current node is a vertex pool with vertices), then continues down the tree.

Reimplemented in EggGroupNode, and EggVertexPool.

Definition at line 410 of file eggNode.cxx.

int ReferenceCount::ref (   )  const [inline, inherited]
 

Explicitly increments the reference count.

User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.

This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.

The return value is the new reference count.

void EggNode::test_under_integrity (   )  const [inherited]

void EggNode::transform_vertices_only (  const LMatrix4d &  mat  )  [inline, inherited]
 

Applies the indicated transformation only to vertices that appear in global space within vertex pools at this node and below.

Joints and other transforms are not affected, nor are local vertices.

Definition at line 352 of file eggNode.I.

int ReferenceCount::unref (   )  const [inline, inherited]
 

Explicitly decrements the reference count.

Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic; plus, we don't have a virtual destructor anyway.) However, see the helper function unref_delete().

User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.

This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.

The return value is the new reference count.

void EggNode::update_under (  int  depth_offset  )  [protected, virtual, inherited]
 

This function is called from within EggGroupNode whenever the parentage of the node has changed.

It should update the depth and under_instance flags accordingly.

depth_offset is the difference between the old depth value and the new value. It should be consistent with the supplied depth value. If it is not, we have some error.

void EggNamedObject::write_header (  ostream &  out,
