Detailed Description

Used as input to intersection functions.

If the intersection function succeeds this struct will contain the nodes that were intersected, the transform matrices from local to global for each intersected node and a vector of IntersectionInfo structs containing information about the intersection for each intersected node geometry. The meaning of global coordinates in the comments regarding this struct refers to the coordinate system of the input to the function for which this struct contains collision information.

Member Function Documentation

◆ pushTransform()

void H3D::Node::NodeIntersectResult::pushTransform ( const Matrix4f & matrix )

inline

Push onto stack of current transforms.

The top is the one that is considered the current transform in calls to getCurrentTransform().

Referenced by H3D::MatrixTransform::closestPoint(), H3D::MatrixTransform::lineIntersect(), and H3D::MatrixTransform::movingSphereIntersect().

Member Data Documentation

◆ collide_invisible

bool H3D::Node::NodeIntersectResult::collide_invisible

Flag used to know if collision function should be called for the children in a ToogleGroup Node even if graphicsOn is false.

The default behaviour is to only collide with visible objects.

Referenced by H3D::ToggleGroup::closestPoint(), H3D::ToggleGroup::lineIntersect(), and H3D::ToggleGroup::movingSphereIntersect().

◆ result

vector< IntersectionInfo > H3D::Node::NodeIntersectResult::result

A vector of HAPI::IntersectionInfo that stores result of intersection such as point and normal.

The point and normal will be in local coordinates of the intersected node. For convenience there is a function called transformResults() which changes the point and normal into global coordinates.

Referenced by H3D::PyNode::closestPoint(), H3D::H3DNavigation::doNavigation(), H3D::PyNode::lineIntersect(), H3D::X3DViewpointNode::translate(), H3D::MagneticGeometryEffect::traverseSG(), and H3D::X3DPointingDeviceSensorNode::updateX3DPointingDeviceSensors().

◆ theNodes

vector< Node * > H3D::Node::NodeIntersectResult::theNodes

A vector of pointers to nodes.

Usually the X3DGeometryNodes that caused the IntersectionInfo results.

Referenced by H3D::PyNode::closestPoint(), H3D::H3DNavigation::doNavigation(), H3D::PyNode::lineIntersect(), and H3D::X3DPointingDeviceSensorNode::updateX3DPointingDeviceSensors().
