◆ foreachTriangle()

template<class Func >
Func StelVertexArray::foreachTriangle ( Func  func) const
inline

call a function for each triangle of the array.

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

OpenGL compatible array of vertex colors to be displayed using arrays.

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

OpenGL compatible array of 3D vertex to be displayed using vertex arrays.

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).
