/*DEVICE SETUP*/
int gpuidx = -1;
for (int idx = 0; idx < IntersectionApi::GetIntersectionDeviceCount(); ++idx) {
IntersectionDeviceInfo const& devinfo(IntersectionApi::GetIntersectionDeviceInfo(idx));
if (devinfo.type == IntersectionDeviceInfo::kGpu && devinfo.apis & IntersectionDeviceInfo::kOpenCl) {
gpuidx = idx;
}
}
int apitype = IntersectionDeviceInfo::kOpenCl;
scene = IntersectionApi::Create(0, &gpuidx, &apitype, 1);
/* SCENE SETUP */
Shape *shape = scene->CreateMesh(&vertex[0].x, numVert, sizeof(vec4), &v->at(0), sizeof(int) * 3, nullptr, numTri/3);
scene->AttachShape(shape);
scene->Commit();
/* BUFFERS SETUP */
hitsGPU = scene->CreateBuffer(hitBufferRayCount * sizeof(Intersection), nullptr);
raysGPU = scene->CreateBuffer(rayBufferRayCount * sizeof(ray), raysCPU);
hitsCPU = (Intersection*)malloc(sizeof(Intersection)*hitBufferRayCount);
raysCPU = (ray*)malloc(sizeof(ray)*rayBufferRayCount);
m_Rays->getData(0, rayBufferRayCount, raysCPU);
scene->IntersectBatch(raysGPU, hitBufferRayCount, hitsGPU, nullptr, &event);
event->Wait();
scene->MapBuffer(hitsGPU, MapType::kMapRead, 0, hitBufferRayCount*sizeof(Intersection), (void**)&hitsCPU, &event);
event->Wait() ;
The call of the IntersectionBatch function results in bad intersections.
i dont know what i am doing wrong.
