<p class="MsoNormal">OpenGL side of things.</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The ES2Texture class appears to handle everything there. There are two create-Methods, but the other</p>
<p class="MsoNormal">one is responsible for MediaFrame stuff and it doesn’t really? make sense to have non-linear filtering there?</p>
<p class="MsoNormal">What’s your opinion?</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The create method seems to parse in all texture parameters simply as arguments (<a href="https://github.com/openjdk/jfx/blob/0d9dcf38275528e1b621d71631aac5bdb9452110/modules/javafx.graphics/src/main/java/com/sun/prism/es2/ES2Texture.java#L98">https://github.com/openjdk/jfx/blob/0d9dcf38275528e1b621d71631aac5bdb9452110/modules/javafx.graphics/src/main/java/com/sun/prism/es2/ES2Texture.java#L98</a>),</p>
<p class="MsoNormal">it would probably be best to just add the filtering in there as well.</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">API-wise it’s probably best to have a Texture or DiffuseMap class that the PhongMaterial uses and stores metadata about the Image.</p>
<p class="MsoNormal">However this might be slightly overkill considering there is only this one single parameter we’re trying to add,</p>
<p class="MsoNormal">thus maybe just a flag in PhongMaterial would suffice?</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Have a nice day,</p>

<span lang="EN-IN">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.</span><span lang="EN-IN" style="font-size:10.0pt"><o:p></o:p></span></p>
