Detailed Description

Stores camera information and is copied to the shader as a uniform buffer.

Member Function Documentation

getEyeCamera()

Backend::TransformCamera Backend::TransformCamera::getEyeCamera	(	int	eye,
		const StereoState &	stereo,
		const StereoState &	prevStereo,
		const Transform &	view,
		const Transform &	previousView,
		Vec2	normalizedJitter
	)		const

Parameters

eye	0 - left eye, 1 - right eye.
stereo	Structure containing information about stereo rendering setup for the current frame.
prevStereo	Structure containing information about stereo rendering setup for the previous frame. Used for TAA.
view	Current view transform.
previousView	View transform from previous frame, used for TAA.
normalizedJitter	For TAA. Jitter should be divided by framebuffer size.

Returns

getMonoCamera()

Backend::TransformCamera Backend::TransformCamera::getMonoCamera	(	bool	isSkybox,
		const Transform &	view,
		Transform	previousView,
		Mat4	previousProjection,
		Vec2	normalizedJitter
	)		const

Parameters

isSkybox	During skybox render pass translation is disabled.
view	Current view transform.
previousView	View transform from previous frame, used for TAA.
previousProjection	Projection from previous frame, used for TAA.
normalizedJitter	For TAA. Jitter should be divided by framebuffer size.

Returns

recomputeDerived()

const Backend::TransformCamera & Backend::TransformCamera::recomputeDerived	(	const Transform &	view,
		const Transform &	previousView,
		const Mat4 &	previousProjection
	)		const

Calculates helper matrices that are derived from ones passed to this object. Is called only from inside getMonoCamera and getStereoCamera.

Parameters

view	Current view transform.
previousView	Transform from previous frame, used for velocity buffer and TAA.
previousProjection	Projection matrix from the previous frame.

Returns

Pointer to this TransformCamera object DOCTODO: can be made private?
