.B PEXOCRender,
.B PEXOCStore,
.B PEXOCRenderSingle
or
.B PEXOCStoreSingle
).
.IP \fIid\fP 1i

.IX PEXGSE-PEXSunGseIdSetSurfTranspCoef
.IX "GSE" "PEXGSE-PEXSunGseIdSetSurfTranspCoef"
.LP
To use the Sun SetSurfaceTransparencyCoefficient GSE, the
.I id
parameter should be set to
.B PEXSunGSEIdSetSurfTranspCoef,
the
.I data
parameter should be set to point to structure type
.I pexSunGseTranspCoef,
and the
.I length
parameter should be set to the total length of
.I data.
.LP
This GSE sets a surface transparency coefficient to be applied when
rendering subsequent surface primitives.
