<p class="MsoNormal"><span style="font-size:11.0pt">Where to put the new methods in the Java side is not the concerning part, it's how to create methods that match all the pipelines. In D3D, the method for setting the filter is detailed in [1], and its possible
parameters in [2][3][4]. So suppose that I'm looking at the list of available filter types there:<o:p></o:p></span></p>
</div>
<p class="MsoNormal"><span style="font-size:11.0pt">D3DTEXF_NONE, D3DTEXF_POINT, D3DTEXF_LINEAR, D3DTEXF_ANISOTROPIC, D3DTEXF_PYRAMIDALQUAD, D3DTEXF_GAUSSIANQUAD, D3DTEXF_CONVOLUTIONMONO,<o:p></o:p></span></p>

<div>
<p class="MsoNormal"><span style="font-size:11.0pt">if OpenGL supports a somewhat different set of filters, we will have some clashes in the Java API side.<o:p></o:p></span></p>

<div>
<p class="MsoNormal"><span style="font-size:11.0pt">Generally, we would like to give as much flexibility to the user as possible, but need to be careful with platform-specific functionality. We could round *some* corners. For example, I think that if we have
an enum for the filter types above that is a union of the ones available in the different pipelines, and if a few are supported by only one of the pipelines, we could note it in the docs and get away with it (something similar to a conditional feature). However,
if the whole native pipeline setup for texture filtering is different, which means a different set of Java API methods per pipeline, then that's too much.<o:p></o:p></span></p>

</div>
<div>
<p class="MsoNormal"><span style="font-size:11.0pt">All this means is that to continue we need to figure out what the API for each pipeline looks like, what's the most functionality we can have for each pipeline, and then how we can unite them into a single
Java API with the hopes of being able to reconcile the differences "well enough" (whatever that will mean).<o:p></o:p></span></p>
