Method Detail

createLocalSolver

public Solver createLocalSolver(boolean sameThread)

Overrides:

createLocalSolver in class PixelwiseRenderer

dispose

protected void dispose(PartialTask task)

Description copied from class: Task

This method is invoked when an active solver is removed or invokes Task.partialTaskDone(Solver) in order to tell this task that the partial task of the solver is no longer processed. Note that the solver may not have completely processed its partial task.

Overrides:

dispose in class PixelwiseRenderer

Parameters:

task - partial task which is no longer processed

done

protected boolean done()

Description copied from class: Task

Returns true iff the complete task has been solved.

Overrides:

done in class PixelwiseRenderer

Returns:

has the task been solved?

getFirstStageImageValue

public float getFirstStageImageValue(int x,
                                     int y)

getPixelsForLine2Vertex

public float[] getPixelsForLine2Vertex(Environment env,
                                       Point3d vertex)

increaseNotMutatedPixels

public void increaseNotMutatedPixels(int count)

initialize

public void initialize(Options opts,
                       ProgressMonitor progress)

Description copied from interface: Renderer

Initializes the renderer. This method has to be invoked at first.

Specified by:

initialize in interface Renderer

Overrides:

initialize in class PixelwiseRenderer

Parameters:

opts - options to use (may be null)

progress - monitor to display rendering progress (may be null)

merge

public void merge(PixelwiseRenderer.Result res)

Overrides:

merge in class PixelwiseRenderer

nextPartialTask

protected PartialTask nextPartialTask(int solverIndex)

Description copied from class: Task

This method returns the next partial task for this task. If all parts of the task have been solved or currently are being solved, null is returned. However, a later invocation may return a partial task if a currently active solver does not completely solve its partial task.

Overrides:

nextPartialTask in class PixelwiseRenderer

Parameters:

solverIndex - index of solver which will be used for next task

Returns:

next partial task, or null

render

public void render(Scene scene,
                   Sensor camera,
                   Matrix4d cameraTransformation,
                   int width,
                   int height,
                   java.awt.image.ImageObserver obs)

Description copied from interface: Renderer

Renders an image of a scene.

Specified by:

render in interface Renderer

Overrides:

render in class PixelwiseRenderer

Parameters:

scene - scene to render

camera - camera to use

cameraTransformation - transformation from camera coordinates to world coordinates

width - width of image

height - height of image

obs - the observer receives the image data

stop

public void stop()

Description copied from class: Task

This method is invoked in order to stop the computation of this task.

Specified by:

stop in interface Renderer

Overrides:

stop in class Task
