Member Function Documentation

virtual StelVertexArray SphericalTexturedPolygon::getFillVertexArray

(

)

const [inline, virtual]

Return an openGL compatible array of texture coords to be used using vertex arrays.

Reimplemented from SphericalRegion.

virtual void SphericalTexturedPolygon::serialize

(

QDataStream &

out

)

const [inline, virtual]

Serialize the region. This method must allow as fast as possible serialization and work with deserialize().

Reimplemented from SphericalPolygon.

void SphericalTexturedPolygon::setContour

(

const QVector< TextureVertex > &

contour

)

[inline]

Set a single contour defining the SphericalPolygon.

Parameters:

contour

a contour defining the polygon area.

void SphericalTexturedPolygon::setContours

(

const QVector< QVector< TextureVertex > > &

contours

)

[inline]

Set the contours defining the SphericalPolygon.

Parameters:

contours

the list of contours defining the polygon area using the WindingPositive winding rule.

virtual QVariantList SphericalTexturedPolygon::toQVariant

(

)

const [virtual]

Serialize the region into a QVariant map matching the JSON format.

The format is:

 ["TEXTURED_POLYGON", [[[ra,dec], [ra,dec], [ra,dec], [ra,dec]], [[ra,dec], [ra,dec], [ra,dec]],[...]],
 [[[u,v],[u,v],[u,v],[u,v]], [[u,v],[u,v],[u,v]], [...]]]

where the two lists are a list of closed contours, with each points defined by ra dec in degree in the ICRS frame followed by a list of texture coordinates in the u,v texture space (between 0 and 1). There must be one texture coordinate for each vertex.

Reimplemented from SphericalPolygon.
