                       int[] aiRImage)
```
    The constructor for the ray tracer. Currently, the only client of this class is VolumeRenderer.
    
    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
- 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 RendererInterfaceColor
    
    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 map has been defined for mapping input colors to intensity.
    
    Specified by:
    
    hasInputMap in interface RendererInterfaceColor
    
    Returns:
    
    boolean True if such a map has been defined.
  - setInput
```
public void setInput(byte[] acImageR,
                     byte[] acImageG,
                     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 RendererInterfaceColor
    
    Parameters:
    
    acImageR - byte[] Array of byte red values for volume.
    
    acImageG - byte[] Array of byte green values for volume.
    
    acImageB - byte[] Array of byte blue values for volume.
    
    acImageA - byte[] Array of byte alpha values for volume.
  - setInputMap
```
public void setInputMap(RendererMapColor kMap)
```
    Specify the lookup table to use for mapping input RGB colors to intensity.
    
    Specified by:
    
    setInputMap in interface RendererInterfaceColor
    
    Parameters:
    
    kMap - Look up table for mapping the color values to intensity.
  - finalize
```
protected void finalize()
                 throws java.lang.Throwable
```
    Calls dispose.
    
    Overrides:
    
    finalize in class RayCastRenderer
    
    Throws:
    
    java.lang.Throwable - DOCUMENT ME!
  - interpolateColor
```
protected final int interpolateColor(javax.vecmath.Point3f kP)
```
    Trilinear interpolation of the image to produce image values at points P that are not at the integer voxel locations.
    
    Parameters:
    
    kP - the spatial point to be assigned an interpolated value
    
    Returns:
    
    The interpolated color value for the point. If kP is not within the bounding box of the image, a value of -1 is returned. Each of the RGB colors is stored in 8 bits with red in bits 16-23, green in bits 8-15, and blue in bits 0-7.
