PixelMap

Deforms any selected NURBS surface depending on the brightness of each pixel of a bitmap image that you use as a map.

How to use

1. Click the SurfDrape icon or choose the Tools > Transform > Deformation > SurfDrape command.

2. Pick the object to deform (it can be a surface, a curve or a polymesh).

3. Pick the spine surface. It must be a NURBS surface consisting of only one NURBS surface. If the object is made up of more than one surfaces only the first will be considered.

4. Pick the reference surface (stretch surface). It must be a NURBS surface object consisting of only one NURBS surface.

5. A stretched copy of the object is created. The original object is hidden but not deleted. In fact, you will find it in Hierarchy Browser hidden from both rendering and views.

Options

Object

To change the object to deform.
Views / Modeling Tool panel. Switch the Replace check button on and pick another object in the scene.

Image

To choose the image that will be used as a deforming map.
Modeling Tool panel. Press the Browse button and choose a bitmap image that will be used to deform the NURBS surface according to the luminance of each pixel.

Depth

To specify the deformation range.
Views. Choose the Edit mode. Click one of the construction vertices and drag it. Release the mouse button when you reach the desired width.
Modeling Tool panel. Set the value either by moving the slider or by typing it in the data field and pressing Enter.

Sampling X res.
Sampling Y res.

To increase or decrease the sampling factor (i.e. the number of control points), along X and Y, of the image used as a map.
Modeling Tool panel. Set the value either by moving the slider or by typing it in the data field and pressing Enter.

Constrained sampl.

To maintain X and Y sampling factors dependent.
Modeling Tool panel. Switch off the check button to disable this option, which is enabled by default.

Smoothness

To increase or decrease smoothness of the new surface.
Modeling Tool panel. Set the value either by moving the slider or by typing it in the data field and pressing Enter.
