<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">Hi:<br><br>I have a question regarding volume rendering with gpu based volume ray casting. <br><br>I'm implementing volume rendering with the vtkGPUVolumeRayCastMapper which <br>gives reliable results for gpu based volume ray cast mappers. However, I'm running<br>into problems with one of the volumes wherein the rendering gives an assertion<br>failure:<br><br>Assertion '"check: positive_low_bounds" && lowBounds[2]>= 0.0"'<br><br>The volume extents for the same seems to be just a point, i.e. 0 298.35, 0 298.835,<br>and 0, 0 which is just a point, yet seems to open up in Volview.<br><br>I looked at the original images and it seems like it's a volumetric scan, (spacing between<br>slices is 0). Please let me know if you have run into this with volumetric images<br>for gpu rendering.<br><br>BTW. Thanks to Francois Bertel for replying to my previous
post regarding the GLX render<br>window error vtk 5.6 which seemed to be something to do with the right rendering<br>context.<br><br>Best regards,<br>
