XRT/3d FAQ

How do I change the XtNxrt3d[Header|Footer][Height|Width] resource?

You cannot change these resources. They are read only.

How do I reduce empty spaces at the side, top and bottom?

You can use XtNxrt3dGraph[X|Y] to position the graph, and XtNxrt3dGraph[Width|Height] to set the height. By changing these resources, you can override the default sizing.

How do I free the memory allocated by Xrt3dMakeGridData()?

Xrt3dDestroyData() function will properly free the memory allocated by Xrt3dMakeGridData().

I get a core dump when my application starts.

One of the most common mistakes is forgetting to use Xrt3dDoubleToArgVal() with floating point resources.
