OpenGL TH3F fails to render [OSX 10.6, ROOT: 5.26]

Hi,

I have generated a TH3F histogram, and it shows up correctly on the Canvas. but when I want to view it in OpenGL (by selecting it from the “View” menu) it get the following error:

Root > Error in TGLLockable::TakeLock: ‘TGLSceneBase unnamed-1’ unable to take DrawLock, already ModifyLock
Warning in TGLViewerBase::PreRender: locking of scene ‘unnamed-1’ failed, skipping.
Error in TGLLockable::TakeLock: ‘TGLSceneBase unnamed-1’ unable to take DrawLock, already ModifyLock
Warning in TGLViewerBase::PreRender: locking of scene ‘unnamed-1’ failed, skipping.

The window shows up, but only with a white screen where the rendering should have been.

Hi,

The GL support for TH3 is preliminary … it support “box” and “iso” options only.

Sorry about that.

Cheers,

Okay, thanks :slight_smile:

Besides a few artifacts, it worked with the BOX option.

Cheers

Strange … can you try tutorials/gl/glbox.C and then just choose “view with gl”.
This one supposedly works ok.
