Functions
Mat3f	candlewick::math::computeNormalMatrix (const Eigen::Affine3f &M)
Camera view-projection utilities.
These functions should be used to construct Camera objects.
Mat4f	candlewick::lookAt (const Float3 &eye, const Float3 &center, const Float3 &up=Float3::UnitZ())
Mat4f	candlewick::perspectiveMatrix (float left, float right, float bottom, float top, float near, float far)
	Compute perspective projection matrix, from clipping plane parameters (left, right, bottom, top, near, far).
Mat4f	candlewick::perspectiveFromFov (Radf fovY, float aspectRatio, float nearZ, float farZ)
	Get perspective projection matrix given fov, aspect ratio, and clipping planes.
Mat4f	candlewick::orthographicMatrix (const Float2 &sizes, float nearZ, float farZ)
	Compute a centered orthographic projection matrix.
Mat4f	candlewick::orthographicMatrix (float left, float right, float bottom, float top, float near, float far)
	Compute an off-center orthographic projection matrix.
float	candlewick::orthoProjNear (const Mat4f &proj)
float	candlewick::orthoProjFar (const Mat4f &proj)
float	candlewick::perspectiveProjNear (const Mat4f &proj)
float	candlewick::perspectiveProjFar (const Mat4f &proj)
FrustumCornersType	candlewick::frustumFromCameraProjection (const Mat4f &camProj)
	Extract the array of frustum corners, given a camera projection matrix.
FrustumCornersType	candlewick::frustumFromCamera (const Camera &camera)
	Get the corners of a Camera's view frustum, in world space.
std::pair< Float3, float >	candlewick::frustumBoundingSphereCenterRadius (const FrustumCornersType &worldSpaceCorners)
