Constructor Detail

RayCastIntensity

protected RayCastIntensity(ModelImage kImage,
                           int iRBound,
                           int[] aiRImage)

The constructor for the ray tracer.

Parameters:

kImage - the 3D image

iRBound - the dimension of the square 2D renderer image

aiRImage - The rendered image data stored in row-major order. Each integer pixel represents an RGB color in the format B | (G << 8) | (R << 16).

Method Detail

disposeLocal

public void disposeLocal(boolean flag)

Clean memory.

Overrides:

disposeLocal in class RayCastRenderer

Parameters:

flag - is true call the super.disposeLocal

hasInputData

public boolean hasInputData()

Return indication as to whether or not the input image data has been specified yet.

Specified by:

hasInputData in interface RendererInterfaceIntensity

Specified by:

hasInputData in class Renderer

Returns:

boolean True if the input image data has been specified.

hasInputMap

public boolean hasInputMap()

Return indication as to whether or not a LUT to use for mapping input intensity values to colors has been specified.

Specified by:

hasInputMap in interface RendererInterfaceIntensity

Returns:

boolean True if such a LUT has been defined.

setInput

public void setInput(byte[] acImageB,
                     byte[] acImageA)

Specify the input volume to use for rendering. The image data stored in order of slice indices, each slice stored in row-major order. That is, slice z=0 is stored first, slice z=1 is stored next, and so on. In slice z=0, the y=0 row is stored first, the y=1 row is stored next, and so on.

Specified by:

setInput in interface RendererInterfaceIntensity

Parameters:

acImageB - byte[] Array of byte intensity values for volume.

acImageA - byte[] Array of byte alpha values for volume.

setInputMap

public void setInputMap(RendererMapIntensity kMap)

Specify the lookup table to use for mapping input intensity values to colors.

Specified by:

setInputMap in interface RendererInterfaceIntensity

Parameters:

kMap - Look up table for mapping the intensity values to colors.

finalize

protected void finalize()
                 throws java.lang.Throwable

Calls dispose.

Overrides:

finalize in class RayCastRenderer

Throws:

java.lang.Throwable - DOCUMENT ME!
