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.

inline

Definition at line 43 of file eggAttributes.I.

◆ 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.

◆ 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.

◆ 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.
