示例1: run
/**
* call CUDA function of the wind node, calculate wind
*/
void NodePointsWind::run()
{
//get input data
DataItem *pointsInput = get_dataitem("PointsInput", true, DATAITEM_POINTSVECTORS_GPU_VECTOR);
std::vector<PointArray> *points = (std::vector<PointArray> *) pointsInput->getDataPointer();
//////Hard code wind variable
int length = 20; //length of the cylinder
Hamtrans::Point center = Hamtrans::Point();
center.x = -5;
center.y = -5;
center.z = -5;
Hamtrans::Point vector = Hamtrans::Point();
vector.x = 1;
vector.y = 1;
vector.z = 1;
Hamtrans::Point end = Hamtrans::Point();
end.x = vector.x * length + center.x;
end.y = vector.y * length + center.y;
end.z = vector.z * length + center.z;
double radius = 10.0;
double speed = 0.0008;
std::vector<PointArray> *resultPoints = NodePointsWindCUDA(points, center, radius, vector, speed, end);
//get output data
