## dilatation en z

Like all linear transformations that command is in 2 modes:
direct and matrix.

## dilz obj

### dilz(c) obj(id)

Z dilates the object of **(c)** with respect to its center of gravity.

**Options:**

**poi(x,y,z)**: with respect to point **(x,y,z)**.

**vertex(s)**: vertex **s**.

**Examples:**

1) `dilz(1.5) vertex[1,5] vol(1,3);`

z dilates vertices (1,2,3,4,5) of
volumes 1 and by (1.5) with respect to point (100,100,200).

2) `dilz(2) var("w")poi(100,100,200);`

z dilates variable named **w** by (2)
with respect to point(100,100,200).

3) dilz(.5) eye view(1): z dilate by .5 the eye of view(1) with respect to origin.
## dilz matrix

### dilz matrix vol(id)

Returns the z expansion coefficient of the matrix of volume **id**.
### dilz(c)matrix vol(id)

Z expands the volume **id** by modifying its matrix.

**Options:**

**ini**: addresses the basic processing.
