Detailed Description

Wrapper around Oculus Rift and its Frame Buffer Objects.

This class is deprecated since the lib_ovr from Oculus completely changed The lib_ovr that connects the Oculus hardware was removed since it only worked for devkit2 under windows.

Destructor calling dispose

Member Function Documentation

bindFramebuffer()

void SLGLOculusFB::bindFramebuffer	(	SLint	scrWidth,
		SLint	scrHeight
	)

Activates the frame buffer. On the first time it calls the updateSize to determine the size and then creates the FBO.

dispose()

void SLGLOculusFB::dispose ( )

private

Deletes the buffer object

drawFramebuffer()

void SLGLOculusFB::drawFramebuffer

(

SLGLProgram *

stereoOculusProgram

)

Draws the intermediate render target (the texture) into the real framebuffer.

generateFBO()

void SLGLOculusFB::generateFBO ( )

private

Frame Buffer generation. This is called from within updateSize because the frame buffer size has to be calculated first

halfWidth()

SLint SLGLOculusFB::halfWidth ( )

inline

height()

SLint SLGLOculusFB::height ( )

inline

texID()

SLuint SLGLOculusFB::texID ( )

inline

updateSize()

void SLGLOculusFB::updateSize	(	SLint	scrWidth,
		SLint	scrHeight
	)

Updates everything when the screen gets resized:

• Recalculates the stereo parameters
• Creates or updates the FBO
• Updates the shader uniforms

width()

SLint SLGLOculusFB::width ( )

inline
