gboolean ogltk_lightsource_set_ambient_color (ogltk_lightsource *light, gfloat red, gfloat green, gfloat blue, gfloat alpha);
Set the lightsource's ambient lighting color.
light : | An ogltk lightsource object |
red : | Red value for this color. |
green : | Green value for this color. |
blue : | Blue value for this color. |
alpha : | Alpha (intensity) value for this color. |
Returns : | TRUE if color has been set. |

Set the lightsource's diffused lighting color.
light : | An ogltk lightsource object |
red : | Red value for this color. |
green : | Green value for this color. |
blue : | Blue value for this color. |
alpha : | Alpha (intensity) value for this color. |
Returns : | TRUE if color has been set. |
gboolean ogltk_lightsource_set_location (ogltk_lightsource *light, gfloat x, gfloat y, gfloat z);
Set the location of the lightsource in the scene.
light : | An ogltk lightsource object |
x : | X axis location in scene |
y : | Y axis location in scene |
z : | Z axis location in scene |
Returns : | TRUE if location has been set. |
gboolean ogltk_lightsource_switch (ogltk_lightsource *light, OgltkLightFlick flick);
Set the lightsources state. Either on or off.
light : | An ogltk lightsource object |
flick : | Light switch state (ON or OFF). |
Returns : | TRUE if the state has been changed. |
OgltkLightFlick ogltk_lightsource_switch_position (ogltk_lightsource *light);
Get the lightsources state. Either On or Off.
light : | An ogltk lightsource object |
Returns : | enumeration type OgltkLightFlick of the lightsources state. |
gboolean ogltk_lightsource_illuminate (ogltk_lightsource *light);
This is called by the scene to render the lightsource in the scene.
light : | An ogltk lightsource object |
Returns : | TRUE if signal was called successfully. |
gboolean ogltk_lightsource_destroy (ogltk_lightsource *light);
Destroy an instance of a lightsource.
light : | An ogltk lightsource object |
Returns : | TRUE if lightsource instance was destroyed. |
