Where to parallelize the program?
From the above profile we can see that the trace function require faster computation time.
Finding the intersection of this ray with the sphere in the scene the algorithm takes a longer .Hence an area to parellelize the program will be here.
for (unsigned i = 0; i < spheres.size(); ++i) {
float t0 = INFINITY, t1 = INFINITY;
if (spheres[i].intersect(rayorig, raydir, t0, t1)) {
if (t0 < 0) t0 = t1;
if (t0 < tnear) {
tnear = t0;
sphere = &spheres[i];
}
}
}
