Notes, screenshots and results using, installing, testing Nvidia Cuda on Linuxmint 18.1
“CUDA is a parallel computing platform and programming model invented by NVIDIA. It enables dramatic increases in computing performance by harnessing the power of the graphics processing unit (GPU).“

sudo apt-get update
sudo apt-get install simplescreenrecorder
Tests done on my custom built Workstation PC as well as Alienware 17 laptop – all GPU specs below.
Quick comparisons [not the focus of this post] :):
- Puget systems laptop, with a GTX 980M 8Gb – 91 billion int./sec, 1819 Gflops
- My Alienware 17 with a GTX 860M 2Gb – 43.3 b.i.p.s, 866 Gflops
- My workstation with a GTX 970 4Gb -> 146 b.i.p.s, 2919 GFlops.
Screenshots in no particular order.
Below result from Puget Systems test on their laptop, for comparison

Red Fibonacci render [using Blender] from a model by Reynante Martinez
Below are interim pictures and notes as l work on using open source tools [ Open street maps, blender etc] and non open source software [ESRI Cityengine, Autodesk Maya] to attempt making a 3D model of downtown Portland Oregon.
I first got interested in something like this while exploring Kludge City Procedural Model MEL Script, written for Autodesk Maya by Ed Whetstone. Click here for his website. To use his MEL scripts, simply copy the downloaded scripts from his website to your Maya scripts folder, in my case to:
My goal is to create a 3D animated video clip flythrough video, using either Blender or Maya, using a basic looking 3d model of an easily recognizablle of downtown Portland, Oregon – not very 3D detailed, just basic building models with extruded heights to start like you see on Google Earth / Microsoft Bing Maps.
This post will be updated as more progress is made.
KludgeCity from Autodesk Maya 3d Software
This powerful program uses a lot of memory and CPU, so be prepared if you use it – below shows it chewing up 6Gb out of my laptops 24Gb. Sometimes l have had to manually using windows task manager kill the cityengine process as well as Maya when the program seems frozen.
With Cityengine, wait a bit for the computations to complete. If the windows cursor is a simple spinning circle after a long while, then its most likely the program is stuck and needs to be restarted.
- created below in Cityengine
- Learnt more on using Cityengine using the ESRI tutorials [data/pdf] found here. [click]
- Found this link. Oregon geospatial data library
- still searching for a small file shapefile of downtown Portland with the height attributes
Below is the settings for using Pixars renderman as installed on my laptop with CityEngine
below is with some heights applied, something is still wrong with the CE rule script.
