Function documentation

DoubleSphereCameraShader& esp::gfx::DoubleSphereCameraShader::setFocalLength(Magnum::Vector2 focalLength)

Set the focal length of the fisheye camera.

Parameters
focalLength the focal length x, y directions
Returns Reference to self (for method chaining)

DoubleSphereCameraShader& esp::gfx::DoubleSphereCameraShader::setPrincipalPointOffset(Magnum::Vector2 offset)

Set the offset of the principal point of the fisheye camera.

Parameters
offset the offset of the principal point in pixels
Returns Reference to self (for method chaining)

Parameters
alpha the alpha value (0.0 <= alpha < 1.0)
Returns Reference to self (for method chaining)

DoubleSphereCameraShader& esp::gfx::DoubleSphereCameraShader::setXi(float xi)

Set the Xi value in the "Double Sphere Camera" model. See details in: Vladyslav Usenko, Nikolaus Demmel and Daniel Cremers: The Double Sphere Camera Model, The International Conference on 3D Vision (3DV), 2018.

Parameters
xi the Xi value
Returns Reference to self (for method chaining)
