Problem in simple volume rendering
Dear Sir/Madam, I am new in yt and trying to visualize my FLASH simulation data (3D) with volume rendering. I followed the cookbook in: http://hg.enzotools.org/cookbook/raw-file/tip/recipes/simple_volume_renderin... However I got an error message: File "/home/kpan2/softwares/yt-x86_64/src/yt-hg/yt/visualization/volume_rendering/software_sampler.py", line 110, in ray_cast LE = na.array(LE) - self.back_center ValueError: shape mismatch: objects cannot be broadcast to a single shape I looked the software_sampler.py file and found all LE, RE, self.bricks are empty lists ( = []), but self.back_center is not and correct. I guess there are some problems when setting self.bricks. If anyone has any suggestions, I would be very happy to hear. Thank you. Best regards, Kuo-Chuan
Hi Kuo-Chuan, Sorry to hear it didn't work for you! Do you think you could help us out with a bit more information, and then we'll see if we can get it working for you? * What is the exact value of back_center that you find? * What is the physical size of your domain? * What is the width you supplied to the volume_rendering object? It might also be easier if you could try it with the "Camera" interface as described here: http://yt.enzotools.org/doc/visualizing/volume_rendering.html#volume-renderi... That should allow for a bit more flexibility in describing the scene, and may help us narrow down the error.
