Typedef Documentation

typedef void(* gmi_analytic_fun)(double const p[2], double x[3], void *u)

the analytic parameterization of a model boundary

Parameters:

	p	the input parametric coordinates. see gmi_eval for the format of this array
	x	the resuting 3D point in space
	u	pointer to user data

Definition at line 27 of file gmi_analytic.h.

typedef void(* gmi_reparam_fun)(double const from[2], double to[2], void *u)

a re-parametrization from one entity to another

Parameters:

	from	the coordinates in the input parametric space
	to	the coordinates in the output parametric space
	u	extra user-provided data

Definition at line 33 of file gmi_analytic.h.

Function Documentation

struct gmi_ent* gmi_add_analytic	(	struct gmi_model *	m,
		int	dim,
		int	tag,
		gmi_analytic_fun	f,
		int *	periodic,
		double(*)	ranges[2],
		void *	user_data
	)			[read]

add an entity to the analytic model

Parameters:

	m	the analytic model
	dim	the dimension of the entity
	tag	the dimension-unique tag for the entity
	f	the analytic function defining the entity. set to NULL for interior entities.
	periodic	for each dimension (d) of the entity, gmi_periodic will return periodic[d]
	ranges	for each dimension (d) of the entity, gmi_range will return ranges[d]
	user_data	pointer that will be passed to analytic function for this entity

void gmi_add_analytic_cell	(	struct gmi_model *	m,
		int	dim,
		int	tag
	)

create a non-parametric model entity

this creates a highest-dimensional model entity. typically users do not create a parametric definition of the 3D regions or 2D faces, since this is equivalent to the analytic function.

void gmi_add_analytic_region	(	struct gmi_model *	m,
		int	tag
	)

gmi_add_analytic_cell(m, 3, tag)

this is provided as a bit of backwards compatibility

void gmi_add_analytic_reparam	(	struct gmi_model *	m,
		struct agm_use	u,
		gmi_reparam_fun	f,
		void *	user_data
	)

add a re-parameterization to the model

given a use (u) which is a piece of a boundary, define the map between the parametric space of the used entity and the parametric space of the using entity.

Parameters:

	m	the analytic model
	u	the model use (see agm.h for how to build this)
	f	the reparameterization code
	user_data	extra data for the re-parameterization code

void* gmi_analytic_data	(	struct gmi_model *	m,
		struct gmi_ent *	e
	)

get the analytic user data

this function returns the pointer passed as (user_data) to gmi_add_analytic when creating entity (e)

void* gmi_analytic_reparam_data	(	struct gmi_model *	m,
		struct agm_use	u
	)

get the re-parameterization user data

this function returns the pointer passed as (user_data) to gmi_add_analytic_reparam when creating entity (e)
