    • print

      public void print(UI.Module m, UI.PrintLevel level, String s)
      Description copied from interface: UserInterface
      Displays some information to the user from the specified module with the specified print level. A user interface is free to show or ignore any message. Level filtering is done in the core and shouldn't be re-implemented by the user interface. All messages will be short enough to fit on one line.
      Specified by:
      print in interface UserInterface
      Parameters:
      m - module the message came from
      level - seriousness of the message
      s - string to display
    • taskStart

      public void taskStart(String s, int min, int max)
      Description copied from interface: UserInterface
      Prepare a progress bar representing a lengthy task. The actual progress is first shown by the call to update and closed when update is closed with the max value. It is currently not possible to nest calls to setTask, so only one task needs to be tracked at a time.
      Specified by:
      taskStart in interface UserInterface
      Parameters:
      s - desriptive string
      min - minimum value of the task
      max - maximum value of the task
    • taskStop

      public void taskStop()
      Description copied from interface: UserInterface
      Closes the current progress bar to indicate the task is over
      Specified by:
      taskStop in interface UserInterface
    • taskUpdate

      public void taskUpdate(int current)
      Description copied from interface: UserInterface
      Updates the current progress bar to a value between the current min and max. When min or max are passed the progressed bar is shown or hidden respectively.
      Specified by:
      taskUpdate in interface UserInterface
      Parameters:
      current - current value of the task in progress.
    • imageBegin

      public void imageBegin(int w, int h, int bucketSize)
      Description copied from interface: Display
      This is called before an image is rendered to indicate how large the rendered image will be. This allows the display driver to write out image headers or allocate surfaces. Bucket size will be 0 when called from a non-bucket based source.
      Specified by:
      imageBegin in interface Display
      Parameters:
      w - width of the rendered image in pixels
      h - height of the rendered image in pixels
      bucketSize - size of the buckets in pixels
    • imageEnd

      public void imageEnd()
      Description copied from interface: Display
      This call is made after the image has been rendered. This allows the display driver to close any open files, write the image to disk or flush any other type of buffers.
      Specified by:
      imageEnd in interface Display
    • imageFill

      public void imageFill(int x, int y, int w, int h, Color c, float alpha)
      Description copied from interface: Display
      Update the current image with a region of flat color. This is used by progressive rendering to render progressively smaller regions of the screen which will overlap. The region is guarenteed to be within the bounds created by the call to imageBegin. No clipping is necessary. Colors are passed in unprocessed. It is up the display driver to do any type of quantization , gamma compensation or tone-mapping needed.
      Specified by:
      imageFill in interface Display
      Parameters:
      x - x coordinate of the region within the image
      y - y coordinate of the region within the image
      w - with of the region in pixels
      h - height of the region in pixels
      c - color to fill the region with
      alpha - pixel coverage
    • imagePrepare

      public void imagePrepare(int x, int y, int w, int h, int id)
      Description copied from interface: Display
      Prepare the specified area to be rendered. This may be used to highlight the work in progress area or simply to setup the display driver to receive the specified portion of the image
      Specified by:
      imagePrepare in interface Display
      Parameters:
      x - x coordinate of the bucket within the image
      y - y coordinate of the bucket within the image
      w - width of the bucket in pixels
      h - height of the bucket in pixels
      id - unique identifier corresponding to the thread which invoked this call
    • imageUpdate

      public void imageUpdate(int x, int y, int w, int h, Color[] data, float[] alpha)
      Description copied from interface: Display
      Update the current image with a bucket of data. The region is guarenteed to be within the bounds created by the call to imageBegin. No clipping is necessary. Colors are passed in unprocessed. It is up the display driver to do any type of quantization, gamma compensation or tone-mapping needed. The array of colors will be exactly w * h long and in row major order.
      Specified by:
      imageUpdate in interface Display
      Parameters:
      x - x coordinate of the bucket within the image
      y - y coordinate of the bucket within the image
      w - width of the bucket in pixels
      h - height of the bucket in pixels
      data - bucket data, this array will be exactly w * h long
      alpha - pixel coverage data, this array will be exactly w * h long
