hm_comparegettransformationmatrix

Returns the 4x4 transformation matrix for a specific transformation.

Syntax

hm_comparegettransformationmatrix transformation_index

Type

HyperMesh Tcl Query Command

Description

Returns the 4x4 transformation matrix (16 values) for a specific transformation. This must be preceded by a call to a relevant hm_compareentities* command.

Inputs

transformation_index: The index of the transformation to query, starting with 0. The number of transformations can be found using hm_comparegettransformationcount.

Example

To find the transformation matrix for transformation 0 for the recursive comparison of surfs 1-20 and 101-120:

*createmark surfs 1 1-20
*createmark surfs 2 101-120
hm_compareinit
hm_compareentitiesrecursive surfs 1 surfs 2 0.1 2 0
set matrix [hm_comparegettransformationmatrix 0]
hm_compareend

Errors

Incorrect usage results in a Tcl error. To detect errors, you can use the catch command:

if { [ catch {command_name...} ] } {
   # Handle error
}
