Salut les gars,VTK java voxel rendu
ne quelqu'un sait, pourquoi ce code en Java compile, mais une erreur apparaît:
"An unrecoverable stack overflow has occurred.
#
# A fatal error has been detected by the Java Runtime Environment:

Voici mon code source java que je copiais de un code C++ ici: http://permalink.gmane.org/gmane.comp.lib.vtk.user/35844
