Detailed Description

Extension of SphericalConvexPolygon for textured polygon.

Constructor & Destructor Documentation

◆ SphericalTexturedConvexPolygon()

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

◆ getFillVertexArray()

virtual StelVertexArray SphericalTexturedConvexPolygon::getFillVertexArray ( const Vec3d observerVelocityForAberration)
virtual

This method is not optimized for SphericalConvexPolygon instances. Return an OpenGL compatible array to be displayed using vertex arrays.

Parameters
observerVelocityForAberrationa vector to add to all contour vertices.

Reimplemented from SphericalConvexPolygon.

◆ setContour()

virtual void SphericalTexturedConvexPolygon::setContour ( const QVector< Vec3d > &  acontour,
const QVector< Vec2f > &  texCoord 
)
inlinevirtual
Parameters
acontoura contour defining the polygon area.
texCoorda list of texture coordinates matching the vertices of the contour.

◆ toQVariant()

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

◆ textureCoords

QVector<Vec2f> SphericalTexturedConvexPolygon::textureCoords
protected

There should be 1 uv position per vertex.
