8fc287c1b7 Added asUpdate/Cull/EventVisitor and asCamera/asDrawable to osg::Object and usage of these within the code base to avoid dynamic_cast<> usage. 2016-01-20 17:49:10 +00:00

7d947d79ff From Wang Rui, "I've found a very covert bug in current VDSM implementation. It makes the computation of positional texgen incorrect if the shadow scene is under one or more child cameras with view/proj offsets. Using current stage instead will fix it." 2012-12-03 10:10:46 +00:00
Robert Osfield
284f410436 Added ShadowSettings::s/getMaximumShadowMapDistance(double) property, usage of these property in ViewDependentShadowMap, 
and setting of it with --max-shadow-distance <double> in the osgshadow example.

52861ecbb0 Added a mutex to protect the removal and addition of Uniform and Program to StateSet to avoid parents being invalidated when multi-threading. 2012-08-14 20:15:00 +00:00

fb83c2b061 Introduced --near-far-mode into osgshadow and ShadowSettings::setComputeNearFarModeOverride(..) to allow user control of how the cull traversal is optimized for computing the depth range of the shadow map. 2012-08-03 16:14:14 +00:00

e5b5494fe1 From Wang Rui, "I'd like to submit a slightly modified version of the ViewDependentShadowMap. It includes two fixes: one is in ComputeLightSpaceBounds::update(), which changes the statement "if (v.z()<0.0f)" to "if (v.z()<-1.0f)" as clipping space coordinates should be transformed to [-1, 1] and should not be discarded unless they go beyond the range; the other is in ViewDependentShadowMap::computeShadowCameraSettings(), in which I changed the line: 
viewMatrix.makeLookAt(frustum.center+positionedLight.lightDir*zMin, frustum.center, lightUp);
to
viewMatrix.makeLookAt(frustum.center+positionedLight.lightDir*zMin, frustum.center+positionedLight.lightDir*zMax, lightUp);

The reason I've done such a change is that for huge scenes like a city on the earth, the values of frustum.center can be extremely large, but zMin may be very small (e.g., when model depth in light coords equals the model radius by chance) in some cases so the result of (eye - center) might jiggle while moving around the shadow scene and thus make the shadow map suddenly disappear some time. The small change here also considers the effect of zMax to avoid such problems.

16c2bb5a2f To fix problems in tight bound computation of the shadow map made the ComputeLightSpaceBounds usage always used when the 
CastShadowMask is active.  Changed the ComputeLightSpaceBounds to use just VIEW_FRUSTUM_CULLING.

d9dbff18a2 Add catch for when shadows are enabled between the update and draw traversals. 2011-10-03 15:57:06 +00:00

e8e25e82a9 From Jean-Sebastien Guay, changed the border colour for the shadow map to be 1 rather the 0 used for debugging so that areas outside the shadow map default to being unshadowed rather than shadowed. 
changed the shadow map texture assigment to StateSet so that it doesn't use OVERRIDE, enabling subgraphs to use the same texture unit for other textures if they so required.
                          tidied up indentation.
