<div dir="auto">Don,</div><div dir="auto"><br></div><div dir="auto">The only thing I can think of is that the border width was originally intended to be in texture space. But then it wouldn’t be SFInt32. Any number of pixels (assuming there’s no possibility of negative pixels) seems okay. My question is, does the border extend beyond the texture?</div><div dir="auto"><br></div><div dir="auto">I am not sure if we should consider aliasing or not.</div><div dir="auto"><br></div><div dir="auto">One also might consider the border be a silhouette boundary of a shape or higher level grouping, if used for highlighting. We should should consider carefully what terminology we use. In this case, it seems like it’s the border of the texture, and has little to do with shapes or groups.</div><div dir="auto"><br></div><div dir="auto">I don’t really see highlights on textures as too useful. How does one select a texture in X3D and not a shape or group?</div><div dir="auto"><br></div><div dir="auto">Thanks!</div><div dir="auto"><br></div><div dir="auto">John</div><div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, Apr 24, 2022 at 2:03 PM Brutzman, Donald (Don) (CIV) <<a href="mailto:brutzman@nps.edu">brutzman@nps.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;padding-left:1ex;border-left-color:rgb(204,204,204)">
