Apply the specified transformation matrix to the 3D points of a specified point cloud or to a 3D geometry.

Syntax

void M3dimMatrixTransform(
    AIL_ID    SrcContainerBufOrGeometry3dgeoId,  //in
    AIL_ID    DstContainerBufOrGeometry3dgeoId,  //out
    AIL_ID    Matrix3dgeoId,                     //in
    AIL_INT64 ControlFlag                        //in
)

Description

This function applies the specified transformation matrix to the 3D points of a specified point cloud or to a 3D geometry.

Note: Note that, when transforming a point cloud, this function affects the coordinates of the points and not their location in the container.

If an M_COMPONENT_NORMALS_AIL component exists in the source container, the component is recalculated then added to the destination container. All other source components are copied to the destination container. Any previously existing components in the destination container are removed.

Parameters

`SrcContainerBufOrGeometry3dgeoId` (in, AIL_ID)

Specifies the source point cloud container or 3D geometry object.

For specifying the source point cloud container or 3D geometry object

Value	Description
`M_XY_PLANE`	Specifies the XY (Z=0) plane.
`Source 3D geometry object identifier`	Specifies the identifier of the source 3D geometry object.

The 3D geometry object must have been previously allocated using M3dgeoAlloc with M_GEOMETRY, and must have been successfully defined.

Note: Note that sphere, box, and cylinder 3D geometry objects do not accept non-uniform scaling. | | Source point cloud container identifier | Specifies the identifier of the source point cloud container.

The container must be 3D-processable (that is, if you call MbufInquireContainer with M_3D_PROCESSABLE, the function returns M_PROCESSABLE). The container must have been previously allocated using MbufAllocContainer with M_PROC. |

`DstContainerBufOrGeometry3dgeoId` (out, AIL_ID)

Specifies the destination container or 3D geometry object.

For specifying the destination container or 3D geometry object

Value	Description
`Destination 3D geometry object identifier`	Specifies the identifier of the destination 3D geometry object.

The 3D geometry object must have been previously allocated using M3dgeoAlloc with M_GEOMETRY. | | Destination container identifier | Specifies the identifier of the destination container.

The container must have been previously allocated using MbufAllocContainer with M_PROC, and must not be a child container. |

`Matrix3dgeoId` (in, AIL_ID)

Specifies the identifier of the transformation matrix object. The transformation matrix object must have been previously allocated using M3dgeoAlloc with M_TRANSFORMATION_MATRIX. The transformation matrix must be any valid affine transformation matrix, where the last row is (0,0,0,1). That is, if you call M3dgeoInquire with M_AFFINE, the function returns M_TRUE.

`ControlFlag` (in, AIL_INT64)

Reserved for future expansion and must be set to M_DEFAULT.
