if sens = 0: Corrects angles such as: |an| > an (value by default).

The corresponding coordinates are processed. For example for c="y"

Points which y is less than d1 are reduced to y = d1 and those whose y isgreater than d2 are reduced to y = d2.

`adjust vol image limit;`

The volume is adjusted in the image window containing pixels of a color other than that of the background.

`adjust vol image precision(eps);`

The comparison is made with an approximation of eps.

`adjust("toto") vol image;`

The (x, y, z) points in the volume are modified by the user function name

p=poi: Retrieves the coordinates of the point space displayed.

k=illum: Retrieves the color (r, g, b) point screen.

t=hsv(k): Retrieved (h, s, v) point screen.

p=fonction(p,k): computes new position

poi(p): validate this position

`adjust exec(c,v1,v2,...) vol image;`

adjust_vol_image_utilisateur function will be executed with the c code and values

Comments:

1)

2) the current image is processed by default.

3) This function allows you to "mount" a relief from a 2D image.

4) All previous forms are combined.

5) Virtually: Build an image (synthesized or digitized). Build a volume (preferably a thin grid front view) invoke

6) Examples:

The

power law 1/3 states that, for a natural movement, this report must be piecewise constant (of the order of 1/1000).

1) yes radius must be active to generate the radii of curvature.

2) Requires law vol(id)=1

For a grid fitted with springs, this function simulates a tissue elastic elongation limited.
