afecdbb46b Moved intial cut of depth partition support into osgViewer::View via two new methods: 
/** Convenience method for setting up multiple slave cameras that depth partition the specified camera.*/
        bool setUpDepthPartitionForCamera(osg::Camera* cameraToPartition, DepthPartitionSettings* dps=0);

        /** Convenience method for setting up multiple slave cameras that depth partition each of the view's active cameras.*/
        bool setUpDepthPartition(DepthPartitionSettings* dsp=0);

920554c4f7 From Wojciech Leandowski, "I removed few lines of code that were setting Threading mode and Screen mode. I believe they are now not neccessary because the same does osgViewer::Viewer argument parser. In fact argument list does not contain these args after they were parsed by osgViewer::Viewer constructor. 
I also allowed myself to add ThreadingHandler to the example."

b3ecb8f38f From Mahai Radu, improvements to handling of spotlights 2007-10-03 12:48:23 +00:00
Robert Osfield
1dc06b4553 From Mihair Radu, "Most of the additions are small utility methods: 
- set the resolution of the shadow map; it calls dirty() to
re-initialize at next update
- keep a list of Shader objects to use instead of the default ones, if
the list is empty, the default shaders are used
- explicitly create the Uniform variables, so that subsequent additions
that require more Uniforms can put them in a central place
- set a Light or LightSource to use explicitly for shadow casting,
allows multiple lights in the scene, with one casting shadows

There are two additions that do not ( yet ) function correctly, but in
the present usage they do not interfere with the regular usage of the
techique:
- support for using spotlights, it's using Light.spotCutoff to determine
if it's a spot-light and not point-light,
   there is an error in the setup of either the shadow camera or the
texgen, most likely due to the direction of the spotlight, since the
position is being used just like in point or directional lights.
- creation of a debugHUD
   the hud is created properly, ( the example included shows it ), but
it displays only white, there has been some discussion of displaying the
shadow map, but I could not find it, the addition of a simple fragment
shader with the appropriate color transform should get this going."

6df0110d0c From Adrian Egli, "update the PSSM, i did some bug fixes and added new features to move the camera virtual against the view direction by applaying a simple distance factor (a), which is calculated camera eye - camera center distance. and we can move the "light camera" against the light direction (b). 
(a) some objects behind the camera can cast shadow
(b) object aboive the camera can cast shadow

then i fixed the shadow map orientation, now screen x coordinate alinged which improve the quality"
