[Visualpython-users] gpu and performance

[Samuel T. S. <arc...@gm...>]

hi, my name is Samuel

I newbie on vpython.
I would like to know if it's possible to do vpython use gpu
and if there is more about performance.

thanks

3. Inclua *seus destinatários* apenas na opção de *cópia oculta (Cco ou Bcc)

Agindo assim *podemos* dificultar a disseminação de vírus, spams e banner.
Acho que vale a pena tentar.

VPython achieves rather good performance because most of the Visual
module is written in C++ for speed. The GPU is used to some extent,
especially for textures/materials.

I suppose you'd get the biggest chunk of speedup already by using hardware 
accelerated 3D graphics through OpenGL. The majority of other operations in 
the core VPython are (I assume) mostly to manage the scene content, and 
therefore not really suitable for accelerating using GPGPU code (like NVidia 
CUDA).

I've done some comparison in rendering through VPython with the visual 
"mockery module" from Mayavi2, and VPython is already blazingly fast. Part of 
that is due to accessing the accelerated 3D features directly, rather than 
basing the code on the VTK abstraction as Mayavi2 does (but Mayavi has got 
good reasons for that, too).

Hope that helps,

Guy
