Constructor & Destructor Documentation

◆ SLHorizonNode()

SLHorizonNode::SLHorizonNode ( SLstring  name,
SLDeviceRotation devRot,
SLTexFont font,
SLstring  shaderDir,
int  scrW,
int  scrH 
)

Construct a new SLHorizonNode::SLHorizonNode object.

Remarks
It is important that during instantiation NO OpenGL functions (gl*) get called because this constructor will be most probably called in a parallel thread from within an SLScene::registerAssetsToLoad or SLScene::assemble function. All objects that get rendered have to do their OpenGL initialization when they are used the first time during rendering in the main thread.
Parameters
nameName of the node
devRotDevice rotation object
fontFont for the text label
shaderDirPath to the shader directory
scrWWidth of the screen in pixels
scrHHeight of the sceen in pixels
