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], unsigned int indices[3]) The method takes arrays of *pointers* as arguments because we can't assume the values are contiguous

StelVertexArray StelVertexArray::removeDiscontinuousTriangles

(

const class StelProjector *

prj

)

const

Create a copy of the array with all the triangles intersecting the projector discontinuty removed.

QVector<unsigned int> StelVertexArray::indices

OpenGL compatible array of indices for the vertex and the textures.

QVector<Vec2f> StelVertexArray::texCoords

OpenGL compatible array of edge flags to be displayed using vertex arrays.

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).
