Detailed Description

A collection of vertices.

There may be any number of vertex pools in a single egg structure. The vertices in a single pool need not necessarily have any connection to each other, but it is necessary that any one primitive (e.g. a polygon) must pull all its vertices from the same pool.

An EggVertexPool is an STL-style container of pointers to EggVertex's. Functions add_vertex() and remove_vertex() are provided to manipulate the list. The list may also be operated on (read-only) via iterators and begin()/end().

Constructor & Destructor Documentation

◆ EggVertexPool()

EggVertexPool::EggVertexPool ( const EggVertexPool & copy )

Copying a vertex pool is of questionable value, since it will copy all of the vertices and assign new pointers to them all.

There will be no polygons referring to the new vertices.

Definition at line 41 of file eggVertexPool.cxx.

Member Function Documentation

◆ add_unused_vertices_to_prim()

void EggVertexPool::add_unused_vertices_to_prim ( EggPrimitive * prim )

Adds all of the unused vertices in this vertex pool to the indicated primitive, in ascending order.

Definition at line 631 of file eggVertexPool.cxx.

References EggPrimitive::add_vertex(), and EggVertex::pref_size().

◆ add_vertex()

EggVertex * EggVertexPool::add_vertex	(	EggVertex *	vertex,
		int	index = `-1`
	)

Adds the indicated vertex to the pool.

It is an error if the vertex is already a member of this or any other pool. The vertex must have been allocated from the free store; its pointer will now be owned by the vertex pool. If the index number is supplied, tries to assign that index number; it is an error if the index number is already in use.

It is possible that a forward reference to this vertex was requested in the past; if so, the data from the supplied vertex is copied onto the forward reference, which becomes the actual vertex. In this case, a different pointer is saved (and returned) than the one actually passed in. In the usual case, however, the vertex pointer passed in is the one that is saved in the vertex pool and returned from this method.

◆ begin()

EggVertexPool::iterator EggVertexPool::begin ( ) const

Returns an iterator that can be used to traverse through all the vertices in the pool.

Definition at line 374 of file eggVertexPool.cxx.

◆ check_overall_color()

void EggVertexPool::check_overall_color	(	bool &	has_overall_color,
		LColor &	overall_color
	)		const

Scans the vertex pool for different colors on different vertices.

If all vertices are the same color, sets has_overall_color to true and fills the color into overall_color. If no vertices have any color, set has_overall_color to true and fills white into overall_color. If at least two vertices have different colors, sets has_overall_color to false.

Definition at line 248 of file eggVertexPool.cxx.

References empty(), and EggAttributes::get_color().

◆ create_unique_vertex()

EggVertex * EggVertexPool::create_unique_vertex ( const EggVertex & copy )

Creates a new vertex in the pool that is a copy of the indicated one and returns it.

If there is already a vertex in the pool like the indicated one, simply returns that one.

Definition at line 472 of file eggVertexPool.cxx.

References add_vertex().

◆ empty()

bool EggVertexPool::empty ( ) const

Returns true if the pool is empty.

◆ end()

EggVertexPool::iterator EggVertexPool::end ( ) const

Returns an iterator that can be used to traverse through all the vertices in the pool.

Definition at line 385 of file eggVertexPool.cxx.

◆ find_matching_vertex()

EggVertex * EggVertexPool::find_matching_vertex ( const EggVertex & copy )

If the EggVertexPool already has a vertex matching the indicated vertex, returns it; otherwise, returns NULL.

This is similar to create_unique_vertex() except that a new vertex is never created.

Definition at line 491 of file eggVertexPool.cxx.

◆ get_aux_names()

void EggVertexPool::get_aux_names ( vector_string & aux_names ) const

Returns the list of auxiliary data names that are defined by any vertices in the pool.

◆ get_forward_vertex()

EggVertex * EggVertexPool::get_forward_vertex ( int index )

Returns the vertex in the pool with the indicated index number.

If there is not a vertex in the pool with the indicated index number, creates a special forward-reference EggVertex that has no data, on the assumption that the vertex pool has not yet been fully read and more data will be available later.

Definition at line 137 of file eggVertexPool.cxx.

◆ get_highest_index()

int EggVertexPool::get_highest_index ( ) const

Returns the highest index number used by any vertex in the pool (except forward references).

Returns -1 if the pool is empty.

Definition at line 156 of file eggVertexPool.cxx.

◆ get_num_dimensions()

int EggVertexPool::get_num_dimensions ( ) const

Returns the maximum number of dimensions used by any vertex in the pool.

◆ get_uv_names()

void EggVertexPool::get_uv_names	(	vector_string &	uv_names,

Returns the list of UV names that are defined by any vertices in the pool, as well as the subset of UV names that actually define 3-d texture coordinates ("uvw_names").

Also returns the subset of UV/UVW names that define a tangent and binormal. It is the user's responsibility to clear both vectors before calling this method.
