foreachTriangle()

template<class Func >

Func StelVertexArray::foreachTriangle ( Func  func ) const

inline

func should define the following method : void operator() (const Vec3d* vertex[3], const Vec2f* tex[3], const Vec3f* colors[3], unsigned int indices[3]) The method takes arrays of pointers as arguments because we can't assume the values are contiguous

Field Documentation

colors

QVector<Vec3f> StelVertexArray::colors

The color (if exists) shall be multiplied with texture to modulate e.g. for extinction of Milky Way or other large items.

vertex

QVector<Vec3d> StelVertexArray::vertex

TODO, move to float? Most of the vectors are normalized, thus the precision is around 1E-45 using float which is enough (=2E-37 milli arcsec).
