Function Documentation

void t8_dtri_compute_reference_coords(const t8_dtri_t *element, const double *ref_coords, const size_t num_coords, const size_t skip_coords, double *out_coords)

Convert points in the reference space of a tri element to points in the reference space of the tree (level 0) embedded in \( [0,1]^2 \).

Parameters:

  • element – [in] Input triangle.

  • ref_coords – [in] The reference coordinates in the triangle (num_coords times \( [0,1]^2 \))

  • num_coords – [in] Number of coordinates to evaluate

  • skip_coords – [in] Only used for batch computation of prisms. In all other cases 0. Skip coordinates in the ref_coords and out_coords array.

  • out_coords – [out] An array of num_coords x 2 x double that will be filled with the reference coordinates of the points on the triangle.
