Code To Investigate

RayTraceContext

public interface RayTraceContext {
	int width();

	int height();

	void mark(int xMin, int yMin, int xMaxExclusive, int yMaxExclusive);

	void markAndRender(int xMin, int yMin, int xMaxExclusive, int yMaxExclusive);
}

Scheduler

public interface Scheduler {
	void void_fork(Runnable runnable);
}

Code To Implement

SplitFourWayRayTracer

class: SplitFourWayRayTracer.java Java.png
methods: rayTrace
package: raytrace.exercise
source folder: student/src/main/java

rayTrace

method: public void rayTrace(RayTraceContext context, Scheduler scheduler) Parallel.svg (parallel implementation required)

LoopRayTracer

class: LoopRayTracer.java Java.png
methods: constructor
sectionsCreator
rayTrace
package: raytrace.exercise
source folder: student/src/main/java

rayTrace

method: public void rayTrace(RayTraceContext context, Scheduler scheduler) Parallel.svg (parallel implementation required)

DivideAndConquerRayTracer

class: DivideAndConquerRayTracer.java Java.png
methods: constructor
thresholdPredicate
rayTraceKernel
package: raytrace.exercise
source folder: student/src/main/java

constructor

method: public DivideAndConquerRayTracer(BiPredicate<Integer, Integer> thresholdPredicate) Sequential.svg (sequential implementation only)

Hang onto the thresholdPredicate in an instance variable. You will need it.

thresholdPredicate

method: public BiPredicate<Integer, Integer> thresholdPredicate() Sequential.svg (sequential implementation only)

Return the thresholdPredicate you stored in an instance variable.

rayTrace

method: public void rayTrace(RayTraceContext context, Scheduler scheduler) Parallel.svg (parallel implementation required)
