makVre::DtCameraStruct Struct Reference

Detailed Description

DtCameraStruct manages a camera view used for rendering to texture for an instrument panel display. It holds the configuration for a specific instrument panel camera, including render target settings, texture properties, and the associated OSG cameras. This struct maintains the relationships between the camera view, its output texture, and the display parameters.

Constructor & Destructor Documentation

DtCameraStruct()

makVre::DtCameraStruct::DtCameraStruct ( makVrv::DtDe & de )

inline

Constructor.

Parameters

de	Reference to the display engine

Creates a new camera structure with default settings. Initializes all camera properties to their default values and associates the structure with the specified display engine.

References cameraType, channelName, de(), mipRtt, modelDef, myDe, observerName, outputTexture, overlayCamera, ownshipId, postDrawCallback, rttCamera, rttIsHud, textureHeight, textureIndex, textureOffsetX, textureOffsetY, textureWidth, makVre::Uninitialized, useCount, and windowName.

Member Function Documentation

viewportChanged()

void makVre::DtCameraStruct::viewportChanged	(	int	x,
		int	y,
		int	w,
		int	h )

Handles viewport size or position changes.

Parameters

x	New x-coordinate of the viewport
y	New y-coordinate of the viewport
w	New width of the viewport
h	New height of the viewport

Updates the camera and render-to-texture configuration when the viewport dimensions or position change. This ensures the rendered output matches the new viewport specifications.

renderTextureChanged()

void makVre::DtCameraStruct::renderTextureChanged

(

)

Handles changes to the render texture.

Updates the camera and associated objects when the render texture properties change. This ensures all components are properly synchronized to use the updated texture.

drawCallback()

void makVre::DtCameraStruct::drawCallback

(

osg::RenderInfo &

renderInfo

)

Callback executed during the rendering process.

Parameters

renderInfo

Rendering information from OSG

This callback is executed during the OSG rendering process. It handles any custom rendering operations needed for this camera, such as setting up texture indices or applying post-processing effects.
