Constructor & Destructor Documentation

SphericalTexturedConvexPolygon::SphericalTexturedConvexPolygon

(

)

[inline]

Default constructor.

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

Constructor from one contour.

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

Special constructor for quads.

Use the 4 textures corners for the 4 vertices.

virtual StelVertexArray SphericalTexturedConvexPolygon::getFillVertexArray

(

)

const [inline, virtual]

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

This method is not optimized for SphericalConvexPolygon instances.

Reimplemented from SphericalConvexPolygon.

virtual void SphericalTexturedConvexPolygon::serialize

(

QDataStream &

out

)

const [inline, virtual]

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

Reimplemented from SphericalConvexPolygon.

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

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.

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.
