A
PolygonMesh primitive is used to store data imported from a standard modeler application.
The
NumVerts,
Data or
DataTx,
NumPolys and
Polys parameters must be defined.
Models are not imported automatically. If you have a model to be converted, please contact AGI for conversion options.
When defining a
PolygonMesh, the
Data or
DataTx keyword must be on a line by itself. In addition, each point (defined by
<x>
,
<y>
and
<z>
or
<x>
,
<y>
,
<z>
<u>
and
<v>
) in the polygon should be on a line by itself.
PolygonMesh primitive parameters
NumVerts <Value>
The
NumVerts parameter defines the number of points contained in the Data or DataTx parameter.
| Parameter | <Value> |
|---|---|
| Range | |
| Default | |
| (R)eal #, (I)nteger? | I |
| Description | Number of unique vertices in the polygon mesh. |
Data <x> <y> <z>
Each row in the
Data parameter specifies one point of the mesh.
If the imported
PolygonMesh has a texture, the
DataTx parameter must be used instead of the
Data parameter
| Parameter | <Value> |
|---|---|
| Range | any real # |
| Default | ____ |
| (R)eal #, (I)nteger? | R |
| Description | Cartesian position of the polygon. |
DataTx <x> <y> <z> <u> <v>
| Parameter | <Value> |
|---|---|
| Range | any real # |
| Default | ____ |
| (R)eal #, (I)nteger? | R |
| Description | Use when applying a texture to the polygon. X, Y and Z positions for each of the points in the polygon, while u and v indicate the texture coordinates. |
NumPolys <Value>
| Parameter | <Value> |
|---|---|
| Range | > 1 |
| Default | |
| (R)eal #, (I)nteger? | I |
| Description | Number of polygons to be drawn. |
Polys
| Parameter | <Value> |
|---|---|
| Range | any real # |
| Default | ____ |
| (R)eal #, (I)nteger? | R |
| Description | Identifies the number of vertices in the polygon. The next three numbers are the values of the polygon vertices to be used, where each value represents the index to the Data point. Indices begin at 0. |
