Overrides:

postFrame in class Filter

Parameters:

renderManager - for rendering

viewPort - for rendering

prevFilterBuffer - the FrameBuffer of the previous filter

sceneBuffer - the FrameBuffer of the scene

initFilter

protected void initFilter(AssetManager manager,
                          RenderManager renderManager,
                          ViewPort vp,
                          int w,
                          int h)

Description copied from class: Filter

Initialization of filter subclasses. This method is called once when the filter is added to the FilterPostProcessor It should contain Material initializations and extra passes initialization

Specified by:

initFilter in class Filter

Parameters:

manager - the assetManager

renderManager - the renderManager

vp - the viewPort where this filter is rendered

w - the width of the filter

h - the height of the filter

Returns:

shadowIntensity

See Also:

setShadowIntensity(float shadowIntensity)

setShadowIntensity

public final void setShadowIntensity(float shadowIntensity)

Set the shadowIntensity, the value should be between 0 and 1, a 0 value gives a bright and invisible shadow, a 1 value gives a pitch black shadow, default is 0.7

returns the edges thickness

Returns:

edgesThickness

See Also:

setEdgesThickness(int edgesThickness)

isFlushQueues

@Deprecated
public boolean isFlushQueues()

Deprecated. does nothing and is kept only for backward compatibility.

isFlushQueues does nothing and is kept only for backward compatibility.

Returns:

false

setShadowCompareMode

public final void setShadowCompareMode(CompareMode compareMode)

Sets the shadow compare mode (see CompareMode for more info).

Parameters:

compareMode - the compare mode.

getShadowCompareMode

public CompareMode getShadowCompareMode()

Get the shadow compare mode.

Returns:

the shadow compare mode.

See Also:

CompareMode

setEdgeFilteringMode

public final void setEdgeFilteringMode(EdgeFilteringMode filterMode)

Sets the filtering mode for shadow edges see EdgeFilteringMode for more info

Parameters:

filterMode - the filtering mode for shadow edges.

setRenderBackFacesShadows

public void setRenderBackFacesShadows(java.lang.Boolean renderBackFacesShadows)

WARNING this parameter is defaulted to true for the shadow filter. Setting it to true, may produce edges artifacts on shadows.

Set to true if you want back faces shadows on geometries. Note that back faces shadows will be blended over dark lighten areas and may produce overly dark lighting.

Setting this parameter will override this parameter for ALL materials in the scene. This also will automatically adjust the face cull mode and the PolyOffset of the pre shadow pass. You can modify them by using getPreShadowForcedRenderState().

If you want to set it differently for each material in the scene you have to use the ShadowRenderer instead of the shadow filter.

Parameters:

renderBackFacesShadows - true if back faces shadows on geometries have to be rendered and false otherwise.

isRenderBackFacesShadows

public boolean isRenderBackFacesShadows()

Is this filter renders back faces shadows.

Returns:

true if this filter renders back faces shadows and false otherwise.

getPreShadowForcedRenderState

public RenderState getPreShadowForcedRenderState()

Get the pre-shadows pass render state. use it to adjust the RenderState parameters of the pre shadow pass. Note that this will be overridden if the preShadow technique in the material has a ForcedRenderState

Returns:

the pre shadow render state.

getEdgeFilteringMode

public EdgeFilteringMode getEdgeFilteringMode()

Get the edge filtering mode.

Returns:

the edge filtering mode.
