public class RayCastIntensityMIP
extends RayCastIntensity

A sample ray tracer that extends RayTrace. The only two necessary member functions are a constructor and an override of 'processRay'. This sample shows how to change the color of the trace whenever a ray intersects a region bounded by a level surface of a specified yellow. In this sample, the color is changed to a yellow hue.

Constructor Detail

RayCastIntensityMIP

public RayCastIntensityMIP(ModelImage kImage,
                           int iRBound,
                           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 << 8) | (R << 16).

Method Detail

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.

processRay

protected final void processRay(javax.vecmath.Point3f p0,
                                javax.vecmath.Point3f p1,
                                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

processRay

protected final 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

processRaySlower

protected void processRaySlower(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.

Parameters:

iIndex - index of the pixel corresponding to the processed ray
