function
MinSG::SVS::VisibilitySphere::VisibilitySphere

public
     
     
VisibilitySphere( Geometry::Sphere_f _sphere,
  const std::vector< SamplePoint > & _samples
)    

Build a new triangulation from the given samples.

Defined in MinSG/Ext/SVS/VisibilitySphere.h:65

function
MinSG::SVS::VisibilitySphere::VisibilitySphere

public
     
     
VisibilitySphere( Geometry::Sphere_f && _sphere,
  std::vector< SamplePoint > && _samples
)    

Move the given sphere and the given samples into the visibility sphere.

Defined in MinSG/Ext/SVS/VisibilitySphere.h:68

function
MinSG::SVS::VisibilitySphere::VisibilitySphere

public
     
     
VisibilitySphere( Geometry::Sphere_f newSphere,
  const std::deque< const VisibilitySphere * > & visibilitySpheres
)    

Build a new visibility sphere. Firstly, the given set of visibility spheres is checked for consistency (same sample positions). Secondly, a new visibility sphere is created for the given sphere and sample positions.

Parameters

newSphere
Geometric representation of the sphere surface of the new visibility sphere
visibilitySpheres
Sampling spheres that are used to create the new visibility sphere

function
MinSG::SVS::VisibilitySphere::evaluateAllSamples

public
     
     
void evaluateAllSamples( FrameContext & frameContext,
  Evaluators::Evaluator & evaluator,
  CameraNodeOrtho * camera,
  Node * node
)    

Iterate over all sample points on the sphere and perform an evaluation for each point. The given evaluator is used for the evaluation.

Parameters

frameContext
Frame context used for rendering
evaluator
Evaluator that is used to generate values
camera
Orthographic camera that is used for rendering
node
Root node of the scene that is given to the evaluator

Defined in MinSG/Ext/SVS/VisibilitySphere.h:118

function
MinSG::SVS::VisibilitySphere::evaluateAllSamples

public
     
     
void evaluateAllSamples( FrameContext & frameContext,
  Evaluators::Evaluator & evaluator,
  CameraNodeOrtho * camera,
  Node * node,
  const std::deque< const VisibilitySphere * > & visibilitySpheres,
  const std::deque< GeometryNode * > & explicitNodes
)    

Iterate over all sample points on the sphere and perform an evaluation for each point. The given evaluator is used for the evaluation. When evaluating a sample point, only those nodes are taken into account, which are visible for at least one of the corresponding sample points of the given visibility spheres, or which are given explicitly.

Parameters

frameContext
Frame context used for rendering
evaluator
Evaluator that is used to generate values
camera
Orthographic camera that is used for rendering
node
Root node of the scene that is given to the evaluator
visibilitySpheres
Visibility spheres that define the visible nodes for the sampling
explicitNodes
Additional nodes that are explicitly taken into account. The range has to be sorted.

Parameters

query
Unit vector
interpolationMethod
See documentation ofinterpolation_type_t

Returns

Visibility information for the queried position
