struct SphericalTexturedPolygon::TextureVertex

Data Fields
Vec2f	texCoord
Vec3d	vertex

Member Function Documentation

void SphericalTexturedPolygon::setContour ( const QVector< TextureVertex > & contour )

inline

Parameters

contour a contour defining the polygon area.

void SphericalTexturedPolygon::setContours ( const QVector< QVector< TextureVertex > > & contours )

inline

Parameters

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

virtual QVariantList SphericalTexturedPolygon::toQVariant ( ) const

virtual

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.
