The
Skin primitive causes two or more cross-sections defined by the
Data points to be connected by a surface, or skin.
The
NumFrames,
NumFramePts, and
Data parameters must be specified in a
Skin primitive.
NumFrames <Value>
| Parameter | <Value> |
|---|---|
| Range | > 2 |
| Default | N/A |
| (R)eal #, (I)nteger? | I |
| Description | Number of cross-sections used to draw the skin. |
NumFramePts <Value>
TheNumFramePts parameter defines the number of cross-sections contained in the Data parameter.
| Parameter | <Value> |
|---|---|
| Range | > 2 |
| Default | N/A |
| (R)eal #, (I)nteger? | I |
| Description | Number of points used in each cross-section. |
Data < x> < y> < z>
Each row in the
Data parameter specifies one point of the
Skin.
When defining a
Skin primitive, the
Data keyword must be on a line by itself. In addition, each point (defined by
<
x>
,
<
y>,
and
<
z>
) of the
Skin must be on a line by itself.
| Parameter | <Value> |
|---|---|
| Range | any real # |
| Default | N/A |
| (R)eal #, (I)nteger? | R |
| Description | X, Y, and Z positions for each of the vertices specified in the two frames. |
OpenFrame
| Parameter | <Value> |
|---|---|
| Range | N/A |
| Default | Frame closed |
| (R)eal #, (I)nteger? | N/A |
| Description | If included in the primitive, the first and last data points are not connected. |
The
CAPESTGEORGE.mdl model uses the
Skin primitive to define the forward deck house:

The total number of points provided should be
NumFrames multiplied by the
NumFramePts.
