Synopsis

Allocate a 3D image processing context.

Syntax

MIL_ID M3dimAlloc(

MIL_ID SysId,	//in
MIL_INT64 ContextType,	//in
MIL_INT64 ControlFlag,	//in
MIL_ID *Context3dimIdPtr	//out

)

Description

This function allocates a 3D image processing context on the specified system. When the 3D image processing context is no longer required, you should release its memory, using M3dimFree().

Note that this function reference has not been updated for a MIL system added during a MIL update. Refer to the MIL system's release note to see if there is complementary information.

Parameters

This function is not supported on the selected boards.

Parameters

SysId

Specifies the identifier of the system on which to allocate the 3D image processing context.

For specifying the system
Value	Description
M_DEFAULT_HOST	Specifies the default Host system of the current MIL application.
MIL system identifier	Specifies a valid system identifier, previously allocated using MsysAlloc().

ContextType

Specifies the type of 3D image processing context to allocate. This parameter must be set to one of the following:

For specifying the context type
Value	Description
M_CALCULATE_MAP_SIZE_CONTEXT	Specifies to allocate a 3D image processing context that can be used with M3dimCalculateMapSize().
M_FILL_GAPS_CONTEXT	Specifies to allocate a 3D image processing context that can be used with M3dimFillGaps().
M_MESH_CONTEXT	Specifies to allocate a 3D image processing context that can be used with M3dimMesh().
M_NORMALS_CONTEXT	Specifies to allocate a 3D image processing context that can be used with M3dimNormals().
M_STATISTICS_CONTEXT	Specifies to allocate a 3D image processing context that can be used with M3dimStat().
M_SUBSAMPLE_CONTEXT	Specifies to allocate a 3D image processing context that can be used with M3dimSample() to perform subsampling.
M_SURFACE_SAMPLE_CONTEXT	Specifies to allocate a 3D image processing context that can be used with M3dimSample() to perform surface sampling.

ControlFlag

Reserved for future expansion and must be set to M_DEFAULT.

Context3dimIdPtr

Specifies the address of the variable in which to write the 3D image processing context identifier. Since the M3dimAlloc() function also returns the identifier, you can set this parameter to M_NULL.

Return value

The returned value is the 3D image processing context identifier if allocation is successful. If allocation fails, M_NULL is returned.
