struct | p8est_geometry_t |
This structure can be created by the user, p4est will never change its contents. More... | |
Typedefs | |
typedef void(* | p8est_geometry_X_t )(p8est_geometry_t *geom, p4est_topidx_t which_tree, const double abc[3], double xyz[3]) |
Forward transformation from vertex frame to physical space. | |
Functions | |
p8est_geometry_t * | p8est_geometry_new_identity (void) |
Create a geometry structure for the identity transformation. | |
p8est_geometry_t * | p8est_geometry_new_shell (double R2, double R1) |
Create a geometry structure for the spherical shell of 24 trees. | |

tranforms from vertex frame to physical space
typedef void(* p8est_geometry_X_t)(p8est_geometry_t *geom, p4est_topidx_t which_tree, const double abc[3], double xyz[3]) |
Forward transformation from vertex frame to physical space.
The vertex space "abc" is defined per octree and spanned by the vertices at its corners; see p8est_connectivity.h. The physical space "xyz" is user-defined, currently used for VTK output.
p8est_geometry_t* p8est_geometry_new_identity | ( | void | ) |
Create a geometry structure for the identity transformation.
This function is just for demonstration since a NULL geometry works too.
p8est_geometry_t* p8est_geometry_new_shell | ( | double | R2, |
double | R1 | ||
) |
Create a geometry structure for the spherical shell of 24 trees.
This is suitable for forests obtained with p8est_connectivity_new_shell.
[in] | R2 | The outer radius of the shell. |
[in] | R1 | The inner radius of the shell. |
p8est_geometry_t* p8est_geometry_new_sphere | ( | double | R2, |
double | R1, | ||
double | R0 | ||
) |
Create a geometry structure for the solid sphere of 13 trees.
This is suitable for forests obtained with p8est_connectivity_new_sphere.
[in] | R2 | The outer radius of the sphere. |
[in] | R1 | The outer radius of the inner shell. |
[in] | R0 | The inner radius of the inner shell. |
