Member Function Documentation

template<class T> void sglPick<T>::setPickFrustum ( const sglMat4< T > & pick_matrix, const sglFrustum< T > & pick_frustum )

Initialize the pick traversal by specifying the pick frustum (in local coordinates) and the transform from the 3D origin to the frustum's origin. Parameters: pick_matrix   The transformation from 3D origin to frustum's origin pick_frustum   The pick frustum with axis along the -Z axis.

template<class T> void sglPick<T>::reset ( ) [virtual]

Reset the previous results and internal variables (including the internal path list). Reimplemented from sglProbeTemplate.

template<class T> sglFrustum< T > & sglPick<T>::getOrigPickFrustum ( ) [inline]

Used internally by the sglBillboard::pick|intersect(..) functions to retrieve the untransformed frustum. Definition at line 87 of file sglPick.hpp.

template<class T> void sglPick<T>::addHit ( const sglGeode * geode, const sglDrawable * geometry )

Add a picked geometry to the PickResult vector. This function will internally fill in the transform and path if those modes have been selected. Parameters: geode   Pointer to the sglGeode containing the picked geometry. geometry   Pointer to the sglDrawable whose bounding box was picked.

template<class T> const vector< PickResult *> & sglPick<T>::getResults ( ) const [inline]

Get a reference to the vector of results Definition at line 102 of file sglPick.hpp.

template<class T> template<class S> void sglPick<T>::pushScale ( S scale, S inv_scale, sglFrustum< T > & old_pick_frustum, sglMat4< T > & old_matrix, sglFrustum< T > & old_view_frustum ) [inline]

scale. Definition at line 107 of file sglPick.hpp.

template<class T> template<class S> void sglPick<T>::pushTranslate ( S tx, S ty, S tz, sglFrustum< T > & old_pick_frustum, sglMat4< T > & old_matrix, sglFrustum< T > & old_view_frustum ) [inline]
