Function Documentation

chiComputeLoadBalancing()

void chi_lua::chiComputeLoadBalancing	(	int	SurfaceHandle,
		table	Xcuts,
		table	Ycuts
	)

Computes load balancing parameters for given predictive x and y cuts without actually performing cuts.

Parameters

SurfaceHandle	int Handle to the surface on which the operation is to be performed.
Xcuts	table Array of x-values associated with the xcuts.
Ycuts	table Array of y-values associated with the ycuts.

chiSurfaceMeshCheckCycles()

void chi_lua::chiSurfaceMeshCheckCycles	(	int	SurfaceHandle,
		int	NumAngles
	)

Builds sweep ordering for a number of angles and checks whether any cyclic dependencies are encountered.

Parameters

SurfaceHandle	int Handle to the surface on which the operation is to be performed.
NumAngles	int Number of azimuthal angles to use for checking cycles.

chiSurfaceMeshExportToObj()

void chi_lua::chiSurfaceMeshExportToObj	(	int	SurfaceHandle,
		char *	FileName
	)

chiSurfaceMeshExtractOpenEdgesToObj()

void chi_lua::chiSurfaceMeshExtractOpenEdgesToObj	(	int	SurfaceHandle,
		char	FileName
	)

Exports all open edges of a surface mesh to file. This is used mostly for graphical error checking.

Parameters

SurfaceHandle	int Handle to the surface on which the operation is to be performed.
FileName	char Filename to which the edges are to be exported.

chiSurfaceMeshImportFromOBJFile()

success chi_lua::chiSurfaceMeshImportFromOBJFile	(	int	SurfaceHandle,
		string	FileName,
		bool	polyflag,
		table3	transform
	)

Loads mesh data from a wavefront object.

Parameters

SurfaceHandle	int Handle to the surface on which the operation is to be performed.
FileName	string Path to the file to be imported.
polyflag	bool (Optional)Flag indicating whether triangles are to be read as polygons. [Default: true (read as polygons)].
transform	table3 (Optional) Translation vector to move all the vertices. [Default: none].

Note:

If the intent of a surface mesh is to serve as a 3D logical volume then the polyFlag parameter should be set to false.

Example

Example usage:

-- Basic example
surfmesh1 = chiSurfaceMeshCreate()
chiSurfaceMeshImportFromOBJFile(surfmesh1, "MeshFile1.obj")
 
-- Surface mesh used as Logical volume
lv_surfmesh1 = chiSurfaceMeshCreate()
chiSurfaceMeshImportFromOBJFile(lv_surfmesh1, "MeshFile3D.obj", false)
 
lv1 = chiLogicalVolumeCreate(SURFACE, lv_surfmesh1)
 
-- Surface mesh with transform
dx = 1.5
dy = -2.5
lv_surfmesh2 = chiSurfaceMeshCreate()
chiSurfaceMeshImportFromOBJFile(lv_surfmesh2, "MeshFile3D.obj", false, {dx,dy,0.0})
 
lv2 = chiLogicalVolumeCreate(SURFACE, lv_surfmesh2)

Returns

success bool Return true if file was successfully loaded and false otherwise.

chiSurfaceMeshImportFromTriangleFiles()

success chi_lua::chiSurfaceMeshImportFromTriangleFiles	(	int	SurfaceHandle,
		char *	FileName,
		bool	polyflag
	)

Loads mesh data from a wavefront object.

Parameters

SurfaceHandle	int Handle to the surface on which the operation is to be performed.
FileName	char* Path to the file to be imported.
polyflag	bool (Optional)Flag indicating whether triangles are to be read as polygons. [Default: true)

Returns

success bool Return true if file was successfully loaded and false otherwise.
