Constructor & Destructor Documentation

SphericalTexturedConvexPolygon::SphericalTexturedConvexPolygon ( )

inline

Default constructor.

SphericalTexturedConvexPolygon::SphericalTexturedConvexPolygon	(	const QVector< Vec3d > &	contour,
		const QVector< Vec2f > &	texCoord
	)

inline

Constructor from one contour.

Definition at line 857 of file StelSphereGeometry.hpp.

		const Vec3d &	e1,
		const Vec3d &	e2,
		const Vec3d &	e3
	)

inline

Special constructor for quads.

Use the 4 textures corners for the 4 vertices.

Definition at line 861 of file StelSphereGeometry.hpp.

Member Function Documentation

virtual StelVertexArray SphericalTexturedConvexPolygon::getFillVertexArray ( ) const

inlinevirtual

Return an openGL compatible array to be displayed using vertex arrays.

This method is not optimized for SphericalConvexPolygon instances.

Reimplemented from SphericalConvexPolygon.

Definition at line 868 of file StelSphereGeometry.hpp.

virtual void SphericalTexturedConvexPolygon::serialize ( QDataStream & out ) const

inlinevirtual

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

Reimplemented from SphericalConvexPolygon.

Definition at line 883 of file StelSphereGeometry.hpp.

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

inlinevirtual

Set a single contour defining the SphericalPolygon.

Parameters

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

Definition at line 873 of file StelSphereGeometry.hpp.

virtual QVariantList SphericalTexturedConvexPolygon::toQVariant ( ) const

virtual

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

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.

Member Data Documentation

QVector<Vec2f> SphericalTexturedConvexPolygon::textureCoords

protected

A list of uv textures coordinates corresponding to the triangle vertices.

There should be 1 uv position per vertex.
