| void osgShadow::SoftShadowMap::setBias | ( | float | bias | ) | [inline] |
Add a small bias to the z-value when calculating the MVPT matrix, this can reduce shadow acne problem.
Suitable values are 0-0.005 Default is 0.
| float osgShadow::SoftShadowMap::getBias | ( | ) | const [inline] |
Return the bias value set used when calculating the MVPT matrix.
| void osgShadow::SoftShadowMap::setSoftnessWidth | ( | const float | softnesswidth | ) |
Set the values for width of the soft penumbra the shader will use.
Zero is for hard shadow (no penumbra). 0.01 is already very soft penumbra. Default is 0.005.
| void osgShadow::SoftShadowMap::setJitteringScale | ( | const float | jitteringscale | ) |
Set the values for jittering scale the shader will use.
Zero is no jittering (i.e. see the banding in penumbra) High values (>64) cause 'pixelization' of the penumbra. Usually but not necessarily power of two number. Default is 32.
| const osg::Vec2& osgShadow::SoftShadowMap::getAmbientBias | ( | ) | const [inline] |
Get the values that are used for the ambient bias in the shader.
| const float osgShadow::SoftShadowMap::getSoftnessWidth | ( | ) | const [inline] |
Get the value used for width of the soft penumbra in the shader.
| const float osgShadow::SoftShadowMap::getJitteringScale | ( | ) | const [inline] |
Get the value used for jittering scale in the shader.
