Method Details

init(gradient)
(Constructor)

Creates a new spherical shader.

The widget takes up all the space allocated for it.

Returns:: The new shader as a GtkWidget.

get_gradient()

Returns: The gradient name. It must not be modified or freed. It may

Returns:: The gradient name. It must not be modified or freed. It may differ the name that was used on initialization or set with Shader.set_gradient(), if the gradient didn't exist or was renamed meanwhile.

get_phi()

Returns: The phi coordinate, in radians. Phi coordinate is orientation

Returns:: The phi coordinate, in radians. Phi coordinate is orientation in horizontal plane, measured from x axis, counterclockwise.

get_theta()

Returns: The theta coordinate, in radians. Theta coordinate is angle from

Returns:: The theta coordinate, in radians. Theta coordinate is angle from sphere's north pole.

get_update_policy()

Returns: The update policy.

Returns:: The update policy.

set_angle(theta, phi)

Sets the spherical angle of a shader.

Parameters:: theta - The theta coordinate to set. See Shader.get_theta() for description. (float); phi - The phi coordinate to set. See Shader.get_phi() for description. (float)

set_gradient(gradient)

Sets the gradient a shader uses.

Parameters:: gradient - Name of gradient shader should use. It should exist. (string)

set_phi(phi)

Sets the phi coordinate of a shader.

Parameters:: phi - The phi coordinate to set. See Shader.get_phi() for description. (float)

set_theta(theta)

Sets the theta coordinate of a shader.

Parameters:: theta - The theta coordinate to set. See Shader.get_theta() for description. (float)

set_update_policy(update_policy)

Sets the update policy of a shader.

Parameters:: update_policy - The update policy shader should use. (GtkUpdateType)
