Detailed Description

Omnidirectional panorama camera.

This class combines six perspective cameras to an omnidirectional camera in a cube map setup.

Member Enumeration Documentation

Cube map side.

The order of the sides must be the order that glTexStorage2D() expects.

Enumerator

gpu_coverage::CameraPanorama::CameraPanorama	(	const size_t &	id,
		Node *const	node
	)

Constructor.

Parameters

[in]	id	Unique ID of the camera.
[in]	node	Scene graph node where to attach this camera.

virtual void gpu_coverage::CameraPanorama::setViewProjection	(	const LocationsMVP &	locationsMVP,
		std::vector< glm::mat4 > &	view
	)		const

virtual

Forward the view and projection matrices to the given locations of a GLSL shader and additionally return the view matrices.

Parameters

[in]	locationsMVP	Struct with variable locations of a GLSL shader.
[out]	view	Will be set to the view matrices.

The view output vector will be resized and filled by the method.

This method uses 6 view matrices, one for each side of a cube map.
