Detailed Description

The set of attributes that may be applied to vertices as well as polygons, such as surface normal and color.

This class cannot inherit from EggObject, because it causes problems at the EggPolygon level with multiple appearances of the EggObject base class. And making EggObject a virtual base class is just no fun.

Member Function Documentation

◆ compare_to()

int EggAttributes::compare_to ( const EggAttributes & other ) const

An ordering operator to compare two vertices for sorting order.

This imposes an arbitrary ordering useful to identify unique vertices.

Definition at line 96 of file eggAttributes.cxx.

Referenced by sorts_less_than().

◆ copy_color()

void EggAttributes::copy_color ( const EggAttributes & other )

inline

Sets this color to be the same as the other's, include morphs.

If the other has no color, this clears the color.

Definition at line 137 of file eggAttributes.I.

References get_color().

Referenced by EggCompositePrimitive::unify_attributes().

◆ copy_normal()

void EggAttributes::copy_normal ( const EggAttributes & other )

inline

Sets this normal to be the same as the other's, include morphs.

If the other has no normal, this clears the normal.

Definition at line 69 of file eggAttributes.I.

Referenced by EggCompositePrimitive::unify_attributes().

◆ get_color()

LColor EggAttributes::get_color ( ) const

inline

Returns the color set on this particular attribute.

If there is no color set, returns white.

Definition at line 91 of file eggAttributes.I.

Referenced by EggVertexPool::check_overall_color(), copy_color(), EggVertexPool::has_nonwhite_colors(), matches_color(), EggPrimitive::post_apply_flat_attribute(), XFileMaterial::set_from_egg(), write(), and EggToDXFLayer::write_polyline().

◆ matches_color()

bool EggAttributes::matches_color ( const EggAttributes & other ) const

inline

Returns true if this color matches that of the other EggAttributes object, include the morph list.

Definition at line 121 of file eggAttributes.I.

References EggMorphList< MorphType >::compare_to(), and get_color().

◆ matches_normal()

bool EggAttributes::matches_normal ( const EggAttributes & other ) const

inline

Returns true if this normal matches that of the other EggAttributes object, include the morph list.

Definition at line 53 of file eggAttributes.I.

References EggMorphList< MorphType >::compare_to().

◆ sorts_less_than()

bool EggAttributes::sorts_less_than ( const EggAttributes & other ) const

inline

An ordering operator to compare two vertices for sorting order.

This imposes an arbitrary ordering useful to identify unique vertices.

Definition at line 151 of file eggAttributes.I.

References compare_to().

◆ transform()

void EggAttributes::transform ( const LMatrix4d & mat )

Applies the indicated transformation matrix to the attributes.

Definition at line 132 of file eggAttributes.cxx.

◆ write()

void EggAttributes::write	(	std::ostream &	out,
		int	indent_level
	)		const

Writes the attributes to the indicated output stream in Egg format.

Definition at line 65 of file eggAttributes.cxx.
