Detailed Description

OpenVR rendering window.

vtkOpenVRRenderWindow is a concrete implementation of the abstract class vtkVRRenderWindow. vtkOpenVRRenderer interfaces to the OpenVR graphics library

This class handles the bulk of interfacing to OpenVR. It supports one renderer currently. The renderer is assumed to cover the entire window which is what makes sense to VR. Overlay renderers can probably be made to work with this but consider how overlays will appear in a HMD if they do not track the viewpoint etc. This class is based on sample code from the OpenVR project.

OpenVR provides HMD and controller positions in "Physical" coordinate system. Origin: user's eye position at the time of calibration. Axis directions: x = user's right; y = user's up; z = user's back. Unit: meter.

Renderer shows actors in World coordinate system. Transformation between Physical and World coordinate systems is defined by PhysicalToWorldMatrix. This matrix determines the user's position and orientation in the rendered scene and scaling (magnification) of rendered actors.

Returns true if the system believes that an HMD is present on the system.

Initialize()

void vtkOpenVRRenderWindow::Initialize ( )

overridevirtual

Initialize the rendering window.

Reimplemented from vtkOpenGLRenderWindow.

Finalize()

void vtkOpenVRRenderWindow::Finalize ( )

overridevirtual

GetHMD()

vr::IVRSystem * vtkOpenVRRenderWindow::GetHMD ( )

inline

Get the system pointer.

MakeRenderWindowInteractor()

vtkRenderWindowInteractor * vtkOpenVRRenderWindow::MakeRenderWindowInteractor ( )

overridevirtual

Create an interactor specific to OpenVR to control renderers in this window.

Implements vtkVRRenderWindow.

Render()

void vtkOpenVRRenderWindow::Render ( )

overridevirtual

Overridden to not release resources that would interfere with an external application's rendering.

Avoiding round trip.

Reimplemented from vtkOpenGLRenderWindow.

StereoMidpoint()

void vtkOpenVRRenderWindow::StereoMidpoint ( )

overridevirtual

Intermediate method performs operations required between the rendering of the left and right eye.

Reimplemented from vtkOpenGLRenderWindow.

StereoRenderComplete()

void vtkOpenVRRenderWindow::StereoRenderComplete ( )

overridevirtual

Handles work required once both views have been rendered when using stereo rendering.

Reimplemented from vtkRenderWindow.

RenderOverlay()

void vtkOpenVRRenderWindow::RenderOverlay

(

)

Draw the overlay.

GetDashboardOverlay()

UpdateHMDMatrixPose()

void vtkOpenVRRenderWindow::UpdateHMDMatrixPose ( )

overridevirtual

Update the HMD pose based on hardware pose and physical to world transform.

VR camera properties are directly modified based on physical to world to simulate

PhysicalTranslation,

PhysicalScale, etc.

Reimplemented from vtkVRRenderWindow.

SetMatrixFromOpenVRPose()

void vtkOpenVRRenderWindow::SetMatrixFromOpenVRPose	(	vtkMatrix4x4 *	result,
		const vr::TrackedDevicePose_t &	vrPose
	)

Convert an OpenVR pose struct to a vtkMatrix4x4 object.

GetOpenVRRenderModels()

vr::IVRRenderModels * vtkOpenVRRenderWindow::GetOpenVRRenderModels ( )

inline

Get the openVR Render Models.

RenderModels()

void vtkOpenVRRenderWindow::RenderModels ( )

overridevirtual

Render the controller and base station models.

Implements vtkVRRenderWindow.

GetOpenVRPose() [1/2]

void vtkOpenVRRenderWindow::GetOpenVRPose ( vtkEventDataDevice  dev, vr::TrackedDevicePose_t **  pose  )

inline

Get the most recent OpenVR pose for a given device.

index is used to disambiguate when there are multiple device handles that map to a device.

GetOpenVRPose() [2/2]

void vtkOpenVRRenderWindow::GetOpenVRPose	(	vtkEventDataDevice	dev,
		uint32_t	index,
		vr::TrackedDevicePose_t **	pose
	)

Get the most recent OpenVR pose for a given device.

index is used to disambiguate when there are multiple device handles that map to a device.

std::string vtkOpenVRRenderWindow::GetWindowTitleFromAPI ( )

overrideprotectedvirtual

Reimplemented from vtkVRRenderWindow.

GetSizeFromAPI()

bool vtkOpenVRRenderWindow::GetSizeFromAPI ( )

overrideprotectedvirtual

Attempt to get the size of the display from the API and store it in this->Size.

If succeed, returns true, else false.

Implements vtkVRRenderWindow.
