Public Methods

explicit CubeMapGenerator(int texture_size = 64)

CubeMapGenerator(const CubeMapGenerator &copy, const osg::CopyOp &copyop = osg::CopyOp::SHALLOW_COPY)

void generateMap(bool use_osg_system = true)

generate the six cube images.

inline osg::Image* getImage(osg::TextureCubeMap::Face face)

inline const osg::Image* getImage(osg::TextureCubeMap::Face face) const

inline void set_pixel(int index, int c, int r, const osg::Vec4 &color)

Protected Methods

virtual ~CubeMapGenerator()

CubeMapGenerator& operator=(const CubeMapGenerator &)

inline static osg::Vec4 vector_to_color(const osg::Vec3 &vec)

virtual osg::Vec4 compute_color(const osg::Vec3 &R) const

override this method to define how colors are computed.

Documentation

This is the base class for cube map generators. It exposes the necessary interface to access the six generated images; descendants should only override the compute_color() method.

explicit CubeMapGenerator(int texture_size = 64)

CubeMapGenerator(const CubeMapGenerator &copy, const osg::CopyOp &copyop = osg::CopyOp::SHALLOW_COPY)

void generateMap(bool use_osg_system = true)

generate the six cube images. If use_osg_system is true, then the OSG's coordinate system is used instead of the default OpenGL one.

virtual ~CubeMapGenerator()

CubeMapGenerator& operator=(const CubeMapGenerator &)

inline static osg::Vec4 vector_to_color(const osg::Vec3 &vec)

virtual osg::Vec4 compute_color(const osg::Vec3 &R) const

override this method to define how colors are computed. The parameter R is the reflection vector, pointing from the center of the cube. The return value should be the RGBA color associated with that reflection ray.

inline osg::Image* getImage(osg::TextureCubeMap::Face face)

inline const osg::Image* getImage(osg::TextureCubeMap::Face face) const

inline void set_pixel(int index, int c, int r, const osg::Vec4 &color)

inline osg::Vec4 vector_to_color(const osg::Vec3 &vec)
