[Bf-gamedev] Scientific Visualization with BGE - DeDaLo

[miroslavhorvath at email.cz]

Hi Roberto,

how many points approximately should BGE handle? What should be a point 
visual representation (dot,cube,sphere)? Will these points be of a regular 
grid shape or have random position?
Currently I'm working on a visualization of point clouds as result of smoke 
particles calculations in OPENFoam. I had to involve LOD system, streaming
(libload) and spatial partitioning of the scene and I'm able to visualize 
over 2 milion points, represented either as cubes(at far distance) or "halo"
faces with various colors(at close distance), where at the close distance it
has to be possible to click on a point and get some information. I haven't 
tried more than 2milion, but I believe BGE could handle even more. This 
project should be done in two months so I hope I'll be allowed to showcase 
it publicly.

Regards,

Miro

"
Hello everybody, 

with the help of some contributors (B2FH(http://www.b2fh.org), ASAIP
(https://asaip.psu.edu/)), I am working on a project for scientific 
visualization of Big Data, in particular for astronomy.
The project is called DeDaLo (shortly described here
(http://www.b2fh.org/DeDaLoProject/tabid/507/Default.aspx)), and will help 
scientists to work in real time with 3D data sets.

We are using Blender and python, and are really interested in the BGE 
future. 
At the present our effort is only on developing a demo of what DeDaLo can 
do, there are no resources to work on BGE code itself.

After this premise, I would ask you about a feature I've read of here
(http://blenderartists.org/forum/showthread.php?256512-Unlimited-Detail-in-the-BGE)
: Point Cloud for BGE. To display hundreds of thousands points is something 
complex, and if you have meshes (faces), it's almost impossible. Is there 
any proposal about Point Cloud in GE?

Thank for your time,
Roberto
