raytracing - Java raytracer increase CPU usage -


i tried implement raytracer in java , works fine. once, rendering scene , checked cpu-usage of program. every virtual core being used overall cpu-usage around 22-23%

i know when rendering cinema4d every virtual core being used 100%.

how archive this? make raytracer run 4 times faster? (23% -> 100%)

you should able 100% cpu usage, , else being equal, doing should result in faster rendering speed. you're apparently not @ 100% indicates me you're either not creating enough threads, or threads blocking on something.

i've found sweet spot 1 rendering thread per virtual core. can use api detect number of cores available @ runtime, , spawn many rendering threads. example of this, see my java ray tracer.

every virtual core being used overall cpu-usage around 22-23%

i'm not sure mean this, may want dig using performance profiler better understand how threads using cpu. ideally want each of threads working time. use visualvm visualize process threads.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
