Hi,
Yes, the documentation is sparse in that area unfortunately.
Something like the following may do it. I've not tested it. Note that it's
SLD 1.1. You can remove the namespace stuff for SLD 1.0.
<se:Geometry>
> <ogc:Function name="pointN">
> <ogc:PropertyName>SDO_GEOMETRY</ogc:PropertyName>
>
> <!--round the result of 0.75 * numPoints as it may be a float-->
> <ogc:Function name="round" />
> <!--Get point 3/4 the way around by multiplying. No div by 0 error
> chance -->
> <ogc:Mul>
> <ogc:Literal>0.75</ogc:Literal>
> <ogc:Function name="numPoints" />
> </ogc:Mul>
> </ogc:Function>
> </ogc:Function>
> </se:Geometry>
Should get you started at least.
Cheers,
Jonathan
