Hi Paul,
I have now added SceneView style methods for controlling the viewer global
light, the new additions to osg::View are:
/** Options for controlling the global lighting used for the view.*/
enum LightingMode
{
NO_LIGHT,
HEADLIGHT,
SKY_LIGHT
};
/** Set the global lighting to use for this view.
* Defaults to headlight. */
void setLightingMode(LightingMode lightingMode);
/** Get the global lighting used for this view.*/
LightingMode getLightingMode() const { return _lightingMode; }
/** Get the global light.*/
void setLight(osg::Light* light) { _light = light; }
/** Get the global lighting if assigned.*/
osg::Light* getLight() { return _light.get(); }
/** Get the const global lighting if assigned.*/
const osg::Light* getLight() const { return _light.get(); }
The default LightingMode is HEADLIGHT, as per SceneView's defaults. Method
calls that once worked with SceneView will work just
the same with osg::View or any of the classes derived from it, such as
osgViewer::Viewer. So the following will now work:
viewer.setLightingMode(osg::Viewer::SKY_LIGHT);
viewer.getLight()->setDiffuse(osg::Vec4(0.9f,0.6f, 0.8f,1.0f));
CompositeViewer manages a list of View's so for this you'll just need do to
viewer.getView(0)->setLightingMode(...) etc.
Robert.
