if s is absent, all vertices are processed.

adjust vol(id) coe(c)

        When several points in the volume id are "equal" to c, facets containing them will refer in the first of them.
Comments:
1) c = 0 by default.
2) This feature is useful for removing multiple points of a volume (eg the facets through the poles of a ball), which may introduce side effects in the "shading".

adjust(d,k) vol(id1) vol(id2)

        Points coincide with those volume id1 volume id2 c near.
1) Useful function to calibrate a volume on another.
2) k =0.25 by default.

adjust(cr,cv,cb) vol(id1) image(id2)

        Z points of volume id1are changed according to the formula:
z -= (cr * r + cv * v + cb * b) / 3
with (r,v,b) = average color of the image in a window with the neighbors of this point.
Options:
illum:each point is processed color image id2.
coe(c): displacement are multiplied by c * r, where = radius of the mesh passing through the treated (if volume is isomorphic to a grid).
Comments:
1) Default automatic antialiasing is performed in a window containing the neighbors of each vertex.
2) adjust vol image alias(a) can control the size of the window:
a < 0: automatic ntialiasing (by default).
a = 0:no antialiasing.
a > 0: Window size a.
hsv: z points of volume id1are changed according to the formula:
z -= (ct * t + cs * s + cv * v) / 3
with (t,s,v) = average (hue,saturation,value) of image id2 in a window containing the neighbors of this point.
limit: the volume is adjuste in the image window containing the pixels whose color is different from that of the background.
precision(eps): the comparison is made with a tolerance of eps.
vertex(s): only the points s will be processed.
Example:
adjust(100,50,30) vol(1)vertex[100,200] image;
adjust("x",crx,cvx,cbx,"y",cry,cvy,cby,"z",crz,cvz,cbz)vol image;
        the coordinates of the volume 1 are changer according to the formulas:
x -= (crx * r + cvx * v + cbx * b) / 3
y -= (cry * r + cvy * v + cby * b) / 3
z -= (crz * r + cvz * v + cbz * b) / 3
adjust("n",cr,cv,cb)vol image
        The points of the volume are moved along their normal:
(cr * r + cv * v + cb * b) / 3
adjust("foo") vol image
        the coordinates of the volume 1 are changer according to the user function name foo where you can use the following commands:
p = poi: retrieves the coordinates of the point space displayed.
k = illum: retrieves the color (r,v,b) of the point.
t = hsv(k): retrieves the(h,s,v) of the point.
p = fonction(p,k): calculates the new position.
poi(p): validates this position.

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

        adjust_vol_image_utilisateur function will be executed with the code and c and values v1,v2,.... You will need to modify this function in the file utilb.c and link again anyflo.
Comments:
1) (cr,cv,cb) = (100,100,100) by default.
2) 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) Use:
build an image (synthesized or digitized).
build a volume (preferably a thin grid view face).
Invoke adjust vol image.
Exemples:
adjust(100,50,-50) vol(1) image;
adjust(100,70,40) vol(1) illum limit vertex[12,120] image(1);
