Member Function Documentation

void osgShadow::SoftShadowMap::createShaders ( )

protectedvirtual

Reimplemented from osgShadow::ShadowMap.

void osgShadow::SoftShadowMap::createUniforms ( )

protectedvirtual

Create the managed Uniforms

Reimplemented from osgShadow::ShadowMap.

float osgShadow::SoftShadowMap::getBias ( ) const

inline

Return the bias value

Definition at line 69 of file SoftShadowMap.h.

float osgShadow::SoftShadowMap::getJitteringScale ( ) const

inline

Get the value used for jittering scale in the shader.

Definition at line 52 of file SoftShadowMap.h.

unsigned int osgShadow::SoftShadowMap::getJitterTextureUnit ( ) const

inline

Get the texture unit that the jitter texture will be applied on.

Definition at line 58 of file SoftShadowMap.h.

float osgShadow::SoftShadowMap::getSoftnessWidth ( ) const

inline

Get the value used for width of the soft penumbra in the shader.

Definition at line 42 of file SoftShadowMap.h.

void osgShadow::SoftShadowMap::initJittering ( osg::StateSet * ss )

protected

osgShadow::SoftShadowMap::META_Object	(	osgShadow	,
		SoftShadowMap
	)

void osgShadow::SoftShadowMap::setBias ( float bias )

inline

Add a small bias to the z-value, this can reduce shadow acne problem. This is the same as calling setPolygonOffset(osg::Vec2(bias,0)); Suitable values are 0-0.005 Default is 0.

Definition at line 66 of file SoftShadowMap.h.

void osgShadow::SoftShadowMap::setJitteringScale ( 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.

void osgShadow::SoftShadowMap::setJitterTextureUnit ( unsigned int jitterTextureUnit )

Set the texture unit that the jitter texture will be applied on.

void osgShadow::SoftShadowMap::setSoftnessWidth ( 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.
