Yan 01d0725a78 [taken]Fix issue #764 An error occurred ... Fix infinity loop in EmitterSphereShape. issue #764 An error occurred I test on both method: public void getRandomPoint1(Vector3f store) { float l = FastMath.pow(FastMath.nextRandomFloat(), 1f / 3f); float u = FastMath.nextRandomFloat() * 2f - 1f; float o = FastMath.nextRandomFloat() * FastMath.TWO_PI; store.z = l * u; u = 1f / FastMath.fastInvSqrt(1f - u * u); store.x = l * u * FastMath.cos(o); store.y = l * u * FastMath.sin(o); store.multLocal(radius); store.addLocal(center); } public void getRandomPoint2(Vector3f store) { do { store.x = (FastMath.nextRandomFloat() * 2f - 1f); store.y = (FastMath.nextRandomFloat() * 2f - 1f); store.z = (FastMath.nextRandomFloat() * 2f - 1f); } while (store.lengthSquared() > 1); store.multLocal(radius); store.addLocal(center); } // Test public void testGetRandomPoint() { int n = 1000000; long start = System.nanoTime(); for (int i = 0; i < n; i++) { getRandomPoint1(store); } long time1 = System.nanoTime() - start; start = System.nanoTime(); for (int i = 0; i < n; i++) { getRandomPoint2(store); } long time2 = System.nanoTime() - start; System.out.println("t1:" + time1); System.out.println("t2:" + time2); System.out.println("t1/t2:" + (float) time1 / time2); } Result: t1:352272158 t2:94436324 t1/t2:3.7302613 Method2 seems nearly 4 times faster than method1.		7 years ago
