Hi, I'm trying to use ParaView built with OpenGL2, hoping to see some speed improvement when I interact with my visualization. Indeed for a complicated geometry I see significant speed up (e.g. ~25 fps with OpenGL2 vs. 5 fps with regular ParaView). But I also see serious errors in the display. I've attached two images of our "g-2 muon storage ring" (never mind what it actually is, though it is very cool :-) ..
[image: Inline image 1] The first, mostly blue image, is from regular ParaView (downloaded Mac binary 4.3.1 64 bit) and is what the ring is supposed to look like. There is a color vector selected and I've unchecked "Map scalars" so that the colors are "true". And indeed the RGB color values in the vector are what is shown on the display. [image: Inline image 2] The next image, with a chunk on the left side missing, is from the OpenGL2 ParaView (Mac built from source 4.3.1-882-gbdceec7 64 bit) configured identically as the other ParaView. So it should look identical to the mostly blue picture. Along with the missing chunk, you see the colors look very wrong. What's even stranger is that the missing chunk is really missing - not invisible - the visualization is made of multiblock datasets, and right clicking where a structure should be only brings up the link camera option. You can try this yourself -- see https://www.dropbox.com/sh/900ocfc90v0w3r6/AACmqz8kVrGPUMnJbpxAFOzBa?dl=0 . The "gm2ring.zip" file has gm2ring.vtm (with the corresponding gm2ring directory) and gm2ring.pvsm to restore my configuration. I'm looking forward to using the OpenGL2 version when it works better. I hope this helps in working out its kinks (or hoping to find out I've built or configured something incorrectly). Let me know how I can help! Thanks! -- Adam *------* *Adam L.
