    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
  - dispose
```
public void dispose()
```

  - setInput
```
public void setInput(byte[] acImageR,

                     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
    
    Overrides:
    
    setInput in class RayCastColor
    
    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
    
    Overrides:
    
    setInputMap in class RayCastColor
    
    Parameters:
    
    kMap - Look up table for mapping the color values to intensity.
  - usesNormals
```
public boolean usesNormals()
```
    Return indication as to whether or not the particular renderer uses normal vectors as part of its implementation.
    
    Specified by:
    
    usesNormals in class Renderer
    
    Returns:
    
    boolean True if the implementation uses normals.

```
protected void finalize()
                 throws java.lang.Throwable
```
    Calls dispose.
    
    Overrides:
    
    finalize in class RayCastColor
    
    Throws:

                          int iIndex,
                          int rayTraceStepSize)
```
    Process a ray that has intersected the oriented bounding box of the 3D image. The method is only called if there is a line segment of intersection. The 'intersectsBox' stores the end points of the line segment in the class members P0 and P1 in image coordinates. P0 and P1 are used in the multi-thread rendering.
    
    Specified by:
    
    processRay in class RayCastRenderer
    
    Parameters:
    
    p0 - ray trace starting point
    
    p1 - ray trace stopping point
    
    iIndex - index of the pixel corresponding to the processed ray
    
    rayTraceStepSize - DOCUMENT ME!
  - processRay
```
protected void processRay(int iIndex,
                          int rayTraceStepSize)
```
    Process a ray that has intersected the oriented bounding box of the 3D image. The method is only called if there is a line segment of intersection. The 'intersectsBox' stores the end points of the line segment in the class members m_kP0 and m_kP1 in image coordinates.
    
    Specified by:
    
    processRay in class RayCastRenderer
    
    Parameters:
    
    iIndex - index of the pixel corresponding to the processed ray

  - traceInit
```
protected void traceInit()
