Constructor & Destructor Documentation

SphericalTexturedConvexPolygon::SphericalTexturedConvexPolygon ( )

inline

Default constructor.

Definition at line 1120 of file StelSphereGeometry.hpp.

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

inline

Constructor from one contour.

Definition at line 1126 of file StelSphereGeometry.hpp.

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.

Definition at line 1135 of file StelSphereGeometry.hpp.

Member Function Documentation

virtual void SphericalTexturedConvexPolygon::drawFillVertexBuffer	(	class StelRenderer *	renderer,
		class StelProjector *	projector
	)

protectedvirtual

Drawing part of drawFill() - assumes the buffer/s is/are generated.

Parameters

renderer	Renderer used for drawing.
projector	Projector to project the vertices (NULL if subdivision is enabled, as in that case the projection is done during buffer generation)

Reimplemented from SphericalConvexPolygon.

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 1169 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 1154 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.

virtual void SphericalTexturedConvexPolygon::updateFillVertexBuffer	(	class StelRenderer *	renderer,
		const DrawParams &	params,
		bool	handleDiscontinuity
	)

protectedvirtual

Update the vertex buffer used by drawFill().

Called when drawing parameters have changed, or when we cannot cache vertices (e.g. when subdividing and this projecting outside Renderer).

Parameters

renderer	Renderer to create vertex buffer.
params	Parameters used for drawing (which also affect vertex generation).
handleDiscontinuity	Do we need to ensure that no triangles cross a projection discontinuity?

Reimplemented from SphericalConvexPolygon.

Member Data Documentation

StelVertexBuffer<TexturedVertex>* SphericalTexturedConvexPolygon::fillTexturedVertexBuffer

protected

Vertex buffer used in our override of drawFill() (using vertices with texcoords).

Definition at line 1177 of file StelSphereGeometry.hpp.

QVector<Vec2f> SphericalTexturedConvexPolygon::textureCoords

protected

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

There should be 1 uv position per vertex.
