Description

Scale Transformation

This block multiplies an input homogeneous transformation matrix by a scaling matrix. The block can be configured to have either a fixed or variable scaling by double clicking on the block and setting the appropriate parameters. The homogeneous translation matrix is as follows:

  output = [x 0 0 0
            0 y 0 0
            0 0 z 0
            0 0 0 1];

where x, y, and z are the scale along the axes of the current frame. The input homogeneous transformation matrix is post-multiplied by this matrix.

Input Ports

4x4

This input takes the previous output from a homogeneous transformation block. If there are no prior transformation blocks then this input must be driven by a Identity Transformation block.

vec

If the block is configured to drive the scale externally, then this port will be visible. The input should be a 3 element vector defining the scaling along the axes of the current frame.

Output Ports

4x4

Outputs a 4x4 tranformation matrix.

Parameters and Dialog Box

Scale Transformation

Source of scale vector

Selects between internal and external sources for the scaling vector. If internal is selected, set the vector in the Scale field. If external is selected, you can connect a 3 element vector to the input port.

Scale

Sets the scaling to the fixed value entered in this field if the Source of scale vector is set to use the internal input.
