in addition to the features of this language, it has hundreds of commands that return an expression syntactically correct and interpreted.

Multiplicity of a command
Simple commands:
A simple command is a command name optionally followed by parameters.
Example:
screen; Clears screen with current color back.
screen(r,g,b); Clears screen with color (r,g,b).
Multiple commands:
A multiple command is a result of command names followed optionally parameters:
Example:
alea(20,30,40) vol(1); Randomly change by 20 (in x), 30 (in y) and 40 (in z)
the vertices of volume 1.
Evaluations
A command ´com1(p1) com2(p2) .... comn(pn)´ is evaluated, ie it returns
a value and / or performs an action.
Examples:
poi(3) vol(1); returns the coordinates of point 3 of Volume 1.
$poi(3) vol(1); prints the coordinates of point 3 of Volume 1.
Assignment
A command ´com1 com .... object(id)=val´ assignes valeu val to the property
´com1 com2 ...´ of the objetc id.
Examples:
poi(3) vol(1)=100,50,0; assignes value (100,50,0) to point 3 of volume 1.
col vertex(3) vol(1)=0,1,0; assignes green color to point 3 of volume 1.
First commande
The first command in a multiple command determines the type of treatment:
If it is an object it is built, examples:
1) cube(1); builds the default cube 1.
2) cube(1)col(0,1,0); build the same cube of green color.
If this transformation is it necessarily applies to an object, eg:
1) tran(0,100,0)vol(1); displaces (0,100,0) the volume 1 (by changing its coordinates).
2) tran(0,100,0)matrix vol(1); displaces (0,100,0) the matrix
of the volume 1 (without changing its coordinates).
If this property is it necessarily applies to an object, eg, examples:
1) col vol(1)=1,0,0; gives red color to thr volume number 1.
2) illum vol(1); returns the coefficients illumination volume number 1.
Les objets
The language objects
Strings, example "AB"
Arrays of strings, example: "MOT1 MOT2 MOT3"
floating-point numbers, example: 1.0
Arrays of numbers, example (1,2.5,-1.0,.3)
Hybrid arrays, example: [1,3],"AB",0
Variables, example x=[1,5], elles peuvent être
automatic,
extern,
global ou
static.
Mathematical functions, example cos, sin, log.
Special functions, example distance, scalar.
User_written functions.
The anyflo objects
They are characterized by a type.
They are known at their creation by their identificator.
Examples:
cube(7)dim(200); Creates volume type cube of side 200, and No. 7.
ball("BB")dim(100)secy(12); rreates the name BB ball with center (0,0,0),
of rayon100 and 12 sections in y.
Object Properties
Objects can be equipped with any number of arbitrary properties. When created certain properties can be set automatically.
For example cube(7)dim(200); creates an object of type cube with:
property 'poi' consists of 8 points.
property 'fac' consists of six facets.
After creating an object properties can be added to it, eg:
illum vol(7)=1; assignes red color to volume 7.
poi(0) vol(7)=0,0,0; adds point (0,0,0) to volume 7.
Access to object properties
Evaluation:
poi(3) vol(1); returns the coordinates of point 3 of volume 1.
illum vertex(3) vol(1); returns the color of vertex 3 of volume 1.
Assignment:
poi(3) vol(1)=100,50,0; assignes (100,50,0) to point 3 of volume 1.
illum vertex(3) vol(1)=0,0,1; assign color blue to vertex 3 of volume 1.
Created:
illum screen vol(1)=1,0,1; creates ´illum screen´ property of volume 1 and
assignes (1,0,1) to it.
func vol(1)="toto"; assignes toto() function toto() to volume 1.
local(0) vol(1)=func "toto"; add local function toto() to volume 1.
The transformations
Objects transformations
All multiple command starting with a transformation command and with a type of object, transforms this object.
Examples:
tran(100,0,0)vol(1); displaces the volume 1 by (100,0,0).
alea(20,30,50)vertex[1,100] vol(1); randomly change by 20 (in x), 30 (in y) and
50 (in z) vertices(1,2,...,100) of volume 1.
The transformation commands
see transformations manual.
