Detailed Description

Constructor & Destructor Documentation

SphericalTexturedConvexPolygon::SphericalTexturedConvexPolygon ( const Vec3d &  e0, const Vec3d &  e1, const Vec3d &  e2, const Vec3d &  e3  )

inline

Use the 4 textures corners for the 4 vertices.

Member Function Documentation

virtual StelVertexArray SphericalTexturedConvexPolygon::getFillVertexArray ( ) const

inlinevirtual

This method is not optimized for SphericalConvexPolygon instances.

Reimplemented from SphericalConvexPolygon.

virtual void SphericalTexturedConvexPolygon::setContour ( const QVector< Vec3d > &  acontour, const QVector< Vec2f > &  texCoord  )

inlinevirtual

Parameters

acontour	a contour defining the polygon area.
texCoord	a list of texture coordinates matching the vertices of the contour.

virtual QVariantList SphericalTexturedConvexPolygon::toQVariant ( ) const

virtual

The format is:

["TEXTURED_CONVEX_POLYGON", [[ra,dec], [ra,dec], [ra,dec], [ra,dec]], [[u,v],[u,v],[u,v],[u,v]]]

where the two lists are a closed convex 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 SphericalConvexPolygon.

Field Documentation

QVector<Vec2f> SphericalTexturedConvexPolygon::textureCoords

protected

There should be 1 uv position per vertex.
