interpol coe(k1,k2,...)image(id1,id2,...)image(id0)

Computes image ni = k1 * id1 + k2 * id2 + ... with ni in (id0,id0+1,...).
Example:
interpol(0.5,0.5)image(1,2)image(3); computes image(3)=average of images 1 and 2.
Options:
dim(nx,ny): size of the images.
limit: evoides color overflow.
normal: Normalizes coefficients (k1 + k2 + ... = 1).
Notes:
1) Faster if images id1,id2,... have the same dimensions.
2) If images i3,i3+1,... doesnot exist, they are created.

interpol(nb)image(id1,id2,...)image(id3)

Generates images id3,id3+1,...,id3+nb-1 interpolated through images id1,id2,... and returns the last generated image number.

interpol(nb)image(id1)image(id2)bitmap

Changes image id2 as id1,id2 interpolating on nb images.
Note:
rem bitmap[0,ni-1]image(id2); is performed in order to fix continuity.

interpol(nb)image(i1)read("A.ee")image(i2)read("B.eee")write("C.eee")

Writes images "Ck.eee" interpolated through images Ai.eee and Bj.eee with i in [i1,i1+nb[, j in [i2,i2+nb[ and k in [1,nb].
Options:
number("nD",i3): k in [i3,i3+nb[ ("4D",1) default.

interpol(nb)image(i1,i2)write("A.eee")

Writes images "Ak.eee" interpolated through images i1 and i2 with k in [1,nb].
Options:
number("nD",i3): k in [i3,i3+nb[ ("4D",1) default.

interpol line

interpol line(L1)line(L2)dim(ni)NP(im)

Returns L = L1 + (L2 - L1) *im / (ni-1).
If im=0 L=L1;
If im=ni-1 L=L2;
Note: requires ni >= 2.

interpol read

interpol read("nom1") read("nom2") write("nom3") coe(c)

Generates the file volumes "nom3" interpolated according to coefficient c between files "nom1" and "nom2".
Notes:
1) nom3 = (1-c) * nom1 + c * nom2
2) By default c = 0.5
3) Useful for generating intermediate frames for example to improve antialiasing or dynamics calculations.
4) interpol read("nom1") read("nom2") write("nom3") coe(c) format("Z");
For compressed files.

interpol read

interpol poi(p1,p2,...,pn-1,pn) vol(id)

Interpolates the points p2,...,pn-1 of volume id between points p1 and pn of this volume.

interpol secx vol

interpol secx(n1,n2) vol(id)

Interpolates the x sections between n1 and n2 (all by default) of volume id.

interpol secy vol

interpol secy(n1,n2) vol(id)

Interpolates the y sections between n1 and n2 (all by default) of volume id.

interpol texture

interpol texture obj(id)=ni

Builds property interpol texture of object type obj id (obj can be vol or image):
       cpt
       ni: number of interpolated images
       debug
       bit1, inc_bit1, number1, nz1
       bit2, inc_bit2, number2, nz2
       law
       fbit1, fbit2
       speed
       type1, type2
       directory number
If obj=vol allows animated textures on grid from 3D images.
See a simple example in basic1_interpol_texture.func
If obj=image allows animated images.

interpol texture bitmap obj(id)

Returns (bit1,bit2)

interpol texture debug(d)obj(id)

sets interpol texture debug obj(id)=d.
if(d==1): debug mode, prints informations.

interpol texture directory obj(id)

Returns directory
interpol texture directory(d)obj(id): changes directory in [1,texture NP[
Allows limit the images to those of this directory.

interpol texture law obj(id)

Returns law

interpol texture law(x1,y1,0, x2,y2,0, ...)obj(id)

Changes law.

interpol texture number obj(id)

Returns number1,number2.

interpol texture number(number1,number2)obj(id)

texture obj(id) is number1,number2 in turn.

interpol texture number(number2)obj(id)

Changes only number2 preserving number1 allowing start a second texture layer (smoothly with option law).

interpol texture secz obj(id)

Returns (nz1,nz2)

interpol texture speed obj(id)

Returns speed of bitmaps.

interpol texture speed (s)ol(id)

Changes this speed.

interpol texture type obj(id)

Returns type
interpol texture type(s)obj(t) or
type interpol texture type obj(t) : changes type
       type(-2): inchanged, changed by: interpol texture number(num)obj(id)
       type(-1): period
       type(0): random
       else: type * speed
Options:
directory(d): relative to the layer d of directories in [1,texture directory NP].

interpol vertex

interpol vertex(v1,v2)vol(id)

Interpolates vertices [v1,v2] of volume id.

interpol vertex(v1,v2,v3)vol(id)

does: poi(v3)vol(id)=(poi(v1)vol(id) + poi(v2)vol(id)) / 2.

interpol vol

interpol vol(id1)vol(id2)vol(id3)coe(c)

Generates volume id3 as centroid of volumes id1 and id2 with coefficients (c) and (1-c).
Notes:
1) c = 0.5 by default
2) Volumes id1 and id2 must have the same topology.
