Q: I built a very simple file in 3DMF binary format. Tumbler can read
it, but Metafile Read cannot (a user break appears). Typing "g" in MacsBug allows Metafile Read
to recover and show the cube. I also get a user break with this file in my application, which uses
the code from the Tumbler example. The user break in MacsBug is crashing the Metrowerks Debugger, so
I am forced to debug with A: You should be able to eliminate the user break problem by replacing your current library with the QuickDraw 3D B1C3 library, which is posted on AppleLink and on the Apple FTP site. The updated source for the metafile-read snippet is also available at these sites. Earlier versions of the library had a number of problems reading metafile data, but these problems have been eliminated in the B1C3 build. The problem of Also, if you are using the Metrowerks Debugger and you find yourself in MacsBug, you can propagate the exception (in the case of PowerPC exceptions) to the high-level debugger by typing GP in MacsBug. |
