Intersections¶

bool ipc::has_intersections(const CollisionMesh& mesh,
    const Eigen::MatrixXd& vertices,
    const std::shared_ptr<BroadPhase> broad_phase
    = make_default_broad_phase());¶

Determine if the mesh has self intersections.

Parameters:¶

const CollisionMesh &mesh¶

The collision mesh.

const Eigen::MatrixXd &vertices¶

Vertices of the collision mesh.

broad_phase_method

The broad phase method to use.

Returns:¶

A boolean for if the mesh has intersections.

bool ipc::is_edge_intersecting_triangle(const Eigen::Vector3d& e0,
    const Eigen::Vector3d& e1, const Eigen::Vector3d& t0,
    const Eigen::Vector3d& t1, const Eigen::Vector3d& t2);¶

Check if an edge intersects a triangle.

Parameters:¶

const Eigen::Vector3d &e0¶

Edge start point.

const Eigen::Vector3d &e1¶

Edge end point.

const Eigen::Vector3d &t0¶

Triangle vertex 0.

const Eigen::Vector3d &t1¶

Triangle vertex 1.

const Eigen::Vector3d &t2¶

Triangle vertex 2.

Returns:¶

True if the edge intersects the triangle.
