template<typename NumericReturnType, typename T>
class drake::multibody::TriangleQuadrature< NumericReturnType, T >
A class for integrating a function using numerical quadrature over triangular domains.
- Template Parameters
-
| NumericReturnType | the output type of the function being integrated. Commonly will be a IEEE floating point scalar (e.g., double), but could be an Eigen::VectorXd, a multibody::SpatialForce, or any other numeric type that supports both scalar multiplication (i.e., operator*(const NumericReturnType&, double) and addition with another of the same type (i.e., operator+(const NumericReturnType&, const NumericReturnType&)). |
| T | the scalar type of the function being integrated over. Supported types are currently only IEEE floating point scalars. |

Numerically integrates the function f over a triangle using the given quadrature rule and the initial value.
- Parameters
-
| f | a function f(p) that returns a numerical value for point p in the domain of the triangle, specified in barycentric coordinates. The barycentric coordinates are given by (p[0], p[1], 1 - p[0] - p[1]). |
| area | the area of the triangle. |

- Parameters
-
| f | a function f(p) that returns a numerical value for point p in the domain of the triangle, specified in barycentric coordinates. The barycentric coordinates are given by (p[0], p[1], p[2]). |
| area | the area of the triangle. |
