Vis.Trans

Function

To convert visual coordinates into robot coordinates (X, Y, and Z).

Syntax

Vis.Trans Cal number, visual coordinate X, visual coordinate Y

Guaranteed entry

Cal number: Designate a Cal data table number (0-31) by integer type data.
Visual coordinate X: Designate the X coordinate of the visual coordinates by single precision real number type data.
Visual coordinate Y: Designate the Y coordinate of the visual coordinates by single precision real number type data.

Return value

Return robot coordinates (X, Y, and Z) by vector type data.

Description

Visual coordinates are converted into robot coordinates (X, Y, and Z).
For about the transformation matrix, refer to the Cal table in Vis.CalTrans.
The data numbers from 0 through 11 on the Cal table correspond to the 12 elements of the transformation matrix.

Attention

Before executing this command, store the transformation matrix in the Cal table with Vis.CalTrans or Vis.SetCalData commands.
Because this command simply calculates X, Y and Z components on the robot coordinate, to execute motion commands, you need to set Rx, Ry and Rz components separately.

Example

' Convert 30 of X coordinate and Y coordinate in visual coordinates 
  of Cal number 1 to robot coordinates

  ccc( 1 ) = 300

  ddd = V( 325, 112.5, 279 )
  eee = V( 200, 112.5, 279 )
  fff = V( 200, -112.5, 279 )

  ' Calibration of visual coordinates and robot coordinates

  ' Assign coordinates position that the visual coordinates are converted to
     robot coordinates (X,Y, and Z)
  hhh = Vis.Trans( 1, 30, 30 )

  ' Display coordinates position that the visual coordinates are converted to
