CUDA Install for Linux (Ubuntu)

There’s some documentation out there for installing the CUDA SDK for Linux and it all seems to be good, though I did run into some little hitches when trying to run programs that take advantage of CUDA.

When running the 64 bit CUDA executable for 3D Coat V4, I received the error, “Error cannot load shared file libcudart.so.3 where is libcudart.so.3”. I found this information for correcting the error using an http://www.cyberciti.biz/faq/set-environment-variable-linux/.

This resulted in the following shell file that I dropped into my home folder.


export LD_LIBRARY_PATH=/usr/local/cuda/lib64
cd /opt/3D-CoatV4-0 && ./3d-coat-64-CUDA

Maybe now, combined with my recently purchased GTX 580, I will see some serious improvemnets in my voxel sculpting and simulations. For good measure, I can’t forget about all the inspiring sculpting work out there.

Playing in 3D

“Playing”?  Did I really just say “PLAYING”?  It must have been due to the time I had off today.  Working on legal stuff (wee), therefore I was away from the PC for most of the day.  After completing my errands, I sat down at my desktop machine, booted up Linux and started playing around with 3D Coat.  It’s similar to ZBrush, in that you can use a drawing tablet to sculpt 3D geometry.  BUT, there’s a key difference.  This uses voxels.  That means that you can literally scupt like clay.  There are non usual polygon limitations.  When you’re done, it’s got plenty of simple retopologizing tools.  Seriously, this has been heaven.

I was curious to see what others have done with the tool. Like myself, people don’t taste it and just walk away, they dive in! This has created a full on 3D sculpting addict out of us.  For example, while looking at this thread, I thought, “Yeah, this is neat and that’s ok.”  But then I saw the image below and had to take a step back.  It doesn’t feel like your classic ZBrush results.  The results from 3D Coat seem to have a more dynamic feel.

Then there’s Ondrej Svadlena, who is praising 3D Coat with, “the voxel sculpting and quadrangulation saved me a lot of time and made things possible that I would probably have never achieved with any other software!” Looking at the images from his short, “Mrdrchain”, I can see what he means. I hope I remember to check back in to see the completed short. In the meantime, you can watch his bizarre short, “Sanitkasan“.

3D Coat doesn’t just sculpt. This voxel stuff is actually relatively new to the package. Apparently it’s primarily used for texturing. Brett Simms has some stunning results in the forums.

While tooling around, I discovered some people using Silo to model, then bringing the resulting models into 3D Coat.  Silo?  Whassat?  That will probably end up in it’s own entry one day.  So many products out there that I’ve not been aware of.
