Teeth are black with H3DAPI 2.1 (XP 0.2.7)

[Daniel Stehn]

After upgrading to H3DAPI 2.1, MEDX3D 1.1 (and Candy 1.9) the teeth are black (see picture). They are still "there" to drill in but with wrong texture (and format?).

X3D::createX3DFromURL seems to run fine but when doing scene->idle(); something happens:

Tried using MedX3d Demo from SenseGraphics to see if we had the same problem. Used the cylinder.nrrd from forssim/examples/ and its texture. As soon as the texture is loaded the cylinder goes black.

Here is the x3d-file generated from MedX3dDemo in case anyone wants to load it into FsWisdom or QtH3DLoad.

[Daniel Stehn (daniel-stehn)]

If we open the generated x3d-file with H3DViewer the topmost segment seems to get rendered by OpacityMapVolumeStyle without the texture while the others are still black.

Works with sensegraphics fix in MedX3d. However we get problems if we build their latest source and use those binaries. The teeth doesn't seem to get loaded at all. If we use the binaries from 2.1 and only replace Medx3d then it works.

Fixed in latest trunk of MedX3d. See http://www.h3dapi.org/modules/mantis/bug_view_page.php?bug_id=0000175 for the full bug report.

Comment from Daniel at SenseGraphics on the change: "Fixed in trunk revision 363. updateUniformFields was not called for styles that did not require lights."
