Synopsis

Allocate a 3D geometry object or transformation matrix object.

Syntax

MIL_ID M3dgeoAlloc(

MIL_ID SysId,	//in
MIL_INT64 ObjectType,	//in
MIL_INT64 ControlFlag,	//in
MIL_ID *GeometryOrMatrix3dgeoIdPtr	//out

)

Description

This function allocates a 3D geometry object or transformation matrix object on the specified system.

Note that 3D geometry objects or transformation matrix objects allocated with M3dgeoAlloc() can be saved using either M3dgeoStream() or M3dgeoSave() and restored using M3dgeoRestore().

When the 3D geometry object or transformation matrix object is no longer required, you should release its memory, using M3dgeoFree().

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 geometry object or transformation matrix object.

For specifying the system identifier
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().

ObjectType

Specifies to allocate a 3D geometry object or transformation matrix object. This parameter must be set to one of the following:

For specifying the object type
Value	Description
M_GEOMETRY	Allocates a 3D geometry object on the specified system.
M_TRANSFORMATION_MATRIX	Allocates a transformation matrix object on the specified system.

ControlFlag

Reserved for future expansion and must be set to M_DEFAULT.

GeometryOrMatrix3dgeoIdPtr

Specifies the address of the variable in which to write the 3D geometry object or transformation matrix object identifier. Since the M3dgeoAlloc() function also returns the identifier, you can set this parameter to M_NULL.

Return value

The returned value is the 3D geometry object or transformation matrix object identifier if allocation is successful. If allocation fails, M_NULL is returned.
