public SdsmFitter(GL4 gl,
 Renderer renderer,
 AssetManager assetManager)

Method Details

fit

public void fit(Texture depthTexture,
 int splitCount,
 Matrix4f cameraToLight,
 float cameraNear,
 float cameraFar)

Initiates an asynchronous fit operation on the given depth texture.

Parameters:

depthTexture - the depth texture to analyze

splitCount - number of cascade splits (1-4)

cameraToLight - transformation matrix from camera clip space to light view space

cameraNear - camera near plane distance

cameraFar - camera far plane distance

getResult

public SdsmFitter.SplitFitResult getResult(boolean wait)

Gets the next available fit result.

Parameters:

wait - if true, blocks until a result is available

Returns:

the fit result, or null if none available (and wait is false)

cleanup

public void cleanup()

Cleans up GPU resources.

setMaxFrameLag

public void setMaxFrameLag(int maxFrameLag)
