Detailed Description

Class for the BVH visualization.

In the standard visualization current node's bounding box, its sibling's bounding box and its childrens' bounding boxes are visualized.

Definition at line 47 of file VisualizationBVH.hpp.

Constructor & Destructor Documentation

VisualizationBVH::VisualizationBVH	(	CudaBVH *	bvh,
		Scene *	scene,
		const Array< AABB > &	emptyBoxes,
		const RayBuffer *	rays = `NULL`,
		Buffer *	visibility = `NULL`
	)

explicit

Constructor.

Parameters

[in]	bvh	CudaBVH to visualize.
[in]	emptyBoxes	Array of empty boxes to be visualized.
[in]	rays	Rays to visualize, pass NULL if no rays should be visualized.
[in]	visibility	Array of triangle visibility flags.

Definition at line 73 of file VisualizationBVH.cpp.

VisualizationBVH::~VisualizationBVH ( void )

Destructor.

Definition at line 181 of file VisualizationBVH.cpp.

Member Function Documentation

void VisualizationBVH::draw	(	GLContext *	gl,
		CameraControls &	camera
	)

virtual

The method used to draw the current state of visualization to the OpenGL context.

Parameters

[in]	gl	OpenGL context to draw into.
[in]	camera	The camera for the current frame.

Implements FW::Visualization.

Definition at line 367 of file VisualizationBVH.cpp.

bool VisualizationBVH::handleEvent ( const Window::Event & ev )

virtual

Handles visualization events - key commands influencing the output.

Parameters

[in] ev Event to process.

Returns: Returns true if the event has been processed.

Implements FW::Window::Listener.

Definition at line 187 of file VisualizationBVH.cpp.

void VisualizationBVH::moveDown ( )

Sets the node to be visualized to be the succesor of the currently visualized node on the set path.

Unlike moveToLeftChild() or moveToRightChild does not change the current path from root to the lowest discovered node. Only changes which node to visualize on this path.

Definition at line 356 of file VisualizationBVH.cpp.

void VisualizationBVH::moveToLeft ( )

Sets the node to be visualized to be the left child of the currently visualized node.

Definition at line 277 of file VisualizationBVH.cpp.

void VisualizationBVH::moveToParent ( )

Sets the node to be visualized to be the parent of the currently visualized node.

Definition at line 234 of file VisualizationBVH.cpp.

void VisualizationBVH::moveToRight ( )

Sets the node to be visualized to be the right child of the currently visualized node.

Definition at line 311 of file VisualizationBVH.cpp.

void VisualizationBVH::moveToSibling ( )

Sets the node to be visualized to be the sibling of the currently visualized node.

Definition at line 247 of file VisualizationBVH.cpp.

void VisualizationBVH::moveUp ( )

Sets the node to be visualized to be the predecesor of the currently visualized node on the set path.

Unlike moveToParent() does not change the current path from root to the lowest discovered node. Only changes which node to visualize on this path.
