Rodin::Geometry::Point class final

#include <Rodin/Geometry/Point.h>

Usage Examples

// Create a point at the centroid of a cell in reference coordinates
Math::SpatialPoint rc(3);
rc << 0.25, 0.25, 0.25;  // Barycentric coords for tetrahedron
Point p(cell, rc);

// Access physical coordinates
std::cout << "x = " << p.x() << ", y = " << p.y() << ", z = " << p.z() << std::endl;

// Compute Jacobian information
const auto& J = p.getJacobian();
Real detJ = p.getJacobianDeterminant();

Thread Safety

Not thread-safe. Each thread should use separate Point instances.
