.SH PARAMETERS
.IP \fIdisplay\fP 1i
A pointer to a display structure returned by a successful
.B XOpenDisplay
call.
.IP \fIresource_id\fP 1i
The resource identifier of the renderer or structure.
.IP \fIreq_type\fP 1i
The request type for the output command (
.B PEXOCRender,
.B PEXOCStore,
.B PEXOCRenderSingle
or
.B PEXOCStoreSingle
).
.IP \fIop\fP 1i
The model clipping volume operator (
.B PEXModelClipReplace
or
.B PEXModelClipIntersection
).
.IP \fIcount\fP 1i
The number of halfspaces.
.IP \fIhalf_spaces\fP 1i
An array of points and normal vectors defining the model clipping volume.
.SH RETURNS
.LP
None
.SH DESCRIPTION
.\" indexing
.IX PEXSetModelClipVolume2D
.LP
This function creates an output primitive attribute which
sets the model clip volume attribute.
This output command is similar to
.BR PEXSetModelClipVolume (3)
except
that the half-spaces are specified in 2D coordinates where the z-component
of each point and normal vector assumed to be zero.
