Will your code compile against sdk3?
It's not necessary any more.
The Oculus SDK v0.4.3 Beta has been released!

Re: FreeCAD-VR: Oculus Rift

Good news: Oculus open-sourced DK1 - Firmware, Schematics, and Mechanicals for the Oculus Rift Development Kit 1. Edit: http://en.zimagez.com/miniature/fcoculus2.png The Rift model it's a good example to test FreeCAD renderer performance/improvements, I think. About 400 000 triangles and most of the...

Re: FreeCAD-VR: Oculus Rift

The new Direct To Rift mode is not even work under Windows with OpenGl, only DirectX so far. Using the Rift as an additional monitor is a pain in the ass. So we will see a lot of driver hacking and changes in the next months! "OpenGL working in Direct HMD mode using Direct3D interoperability (updat...

Re: FreeCAD-VR: Oculus Rift

But how difficult and how much work would it be to make this work? It uses a smartphone, so you have 2 options: a) video streaming from PC, unacceptable bacause of latency (compression+transmission+decompression > 50ms) b) port FreeCAD (or Coin3D viewer) to Android. It could work, see Samsung Gear ...

Re: script saving color to an OBJ file?

roegel wrote:OBJ files can contain color information, but I do not know how to save that color.
AFAIK it's not true. OBJ cannot contain colour information for vertex or face. You can specify a material in an external *.mtl file and then use it.

Re: Units, trying to get correct results with Calculix

The same holds for forces applied to faces: They must be [N/m^2] to be well defined as you need to calculate the per mesh node force via the surface of the elements. So it have to be calculated inside Calculix. Here are two inp files (vanilla FreeCAD): for 10x10x10 box (1N/mm^2(?) force on the 9 no...
