void EggNode::adjust_under | ( | ) | [protected, virtual, inherited] |
This is called within update_under() after all the various under settings have been inherited directly from the parent node.
It is responsible for adjusting these settings to reflect states local to the current node; for instance, an <Instance> node will force the UF_under_instance bit on.

void EggPrimitive::apply_first_attribute | ( | ) | [virtual, inherited] |
Sets the first vertex of the triangle (or each component) to the primitive normal and/or color, if the primitive is flat-shaded.
This reflects the DirectX convention of storing flat-shaded properties on the first vertex, although it is not usually a convention in Egg.
This may introduce redundant vertices to the vertex pool.

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 <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.

void EggPrimitive::remove_doubled_verts | ( | bool | closed | ) | [inherited] |
Certain kinds of primitives, particularly polygons, don't like to have the same vertex repeated consecutively.
Unfortunately, some modeling programs (like MultiGen) make this an easy mistake to make.
It's handy to have a function to remove these redundant vertices. If closed is true, it also checks that the first and last vertices are not the same.
This function identifies repeated vertices by position only; it does not consider any other properties, such as color or UV, significant in differentiating vertices.

void EggRenderMode::set_bin | ( | const string & | bin | ) | [inline, inherited] |
Sets the "bin" string for this particular object.
This names a particular bin in which the object should be rendered. The exact meaning of a bin is implementation defined, but generally a GeomBin matching each bin name must also be specifically added to the rendering engine (e.g. the CullTraverser) in use for this to work. See also set_draw_order().

void EggNurbsSurface::set_num_u_knots | ( | int | num | ) |
Directly changes the number of knots in the U direction.
This will either add zero-valued knots onto the end, or truncate knot values from the end, depending on whether the list is being increased or decreased. If possible, it is preferable to use the setup() method instead of directly setting the number of knots, as this may result in an invalid surface.

void EggObject::set_user_data | ( | EggUserData * | user_data | ) | [inherited] |
Sets the user data associated with this object.
This may be any EggUserData-derived object. The egg library will do nothing with this pointer, except to hold its reference count and return the pointer on request.
The EggObject maintains multiple different EggUserData pointers, one for each unique type (as reported by get_type()). If you know that only one type of EggUserData object will be added in your application, you may use the query functions that accept no parameters, but it is recommended that in general you pass in the type of your particular user data, to allow multiple applications to coexist in the same egg data.
This pointer is also copied by the copy assignment operator and copy constructor.

Prepares a new surface definition with the indicated order and number of knots in each dimension.

void EggPrimitive::unify_attributes | ( | EggPrimitive::Shading | shading | ) | [virtual, inherited] |
If the shading property is S_per_vertex, ensures that all vertices have a normal and a color, and the overall primitive does not.
If the shading property is S_per_face, and this is a composite primitive, ensures that all components have a normal and a color, and the vertices and overall primitive do not. (If this is a simple primitive, S_per_face works the same as S_overall, below).
If the shading property is S_overall, ensures that no vertices or components have a normal or a color, and the overall primitive does (if any exists at all).
After this call, either the primitive will have normals or its vertices will, but not both. Ditto for colors.
This may create redundant vertices in the vertex pool.

bool ReferenceCount::unref | ( | ) | const [inline, virtual, 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.) 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 true if the new reference count is nonzero, false if it is zero.
