How to handle the *.iv file from yorik in his first post?

You can open it Menu File -> open ...
but it does not work for me,
there is no ShadowGroup support in the pivy so the file does not have an effekt.
I will look how to get this ShadowGroup running

here is another iv file with a bit more action

Code: Select all

#Inventor V2.1 ascii

  # to get some lighting when headlight is turned off in the viewer
  DirectionalLight { direction 0 0 -1 intensity 0.2 }
  ShadowGroup {
    quality 1 # to get per pixel lighting
   # ShadowStyle { style NO_SHADOWING }
    SpotLight {
      location -8 -8 8.0
      direction 1 1 -1
      cutOffAngle 0.35
      dropOffRate 0.7
    }
    ShadowStyle { style SHADOWED }
    Separator {
      Complexity { value 1.0 }
      Material { diffuseColor 1 1 0 specularColor 1 1 1 shininess 0.9 }
      Shuttle { translation0 -3 1 0 translation1 3 -5 0 speed 0.25 on TRUE }

No success. I copy your code into a file and named it thomas.iv
If I open it, there is nothing, but if I open the *.iv from yorik there is a plane and a light reflecting on it.

[microelly2]

here as a file

shadow.iv

(1.43 KiB) Downloaded 28 times

yoriks files shows a plane and a reflexion of course but the shadow does not work.

[yorik]

Note that loading the iv file from the FreeCAD File menu doesn't make use of pivy.

My computer has two GPUs, the one that is bundled inside the i7 processor and an nvidia GPU. If I run FreeCAD on the i7 GPU (using mesa drivers on linux), the shadows don't appear. If I use the nvidia GPU instead (with the proprietary driver), then the shadows are there. So the problem is probably between Coin and the OpenGL support that the driver offers...

hello Yorik, which coin do you use?

So I really need other hardware to get shadows.
For the moment this is my way to get light and darkness

phpBB [video]

there are some light nodes and lets see what other open inventor effects can be put into this tool.

[looo]

SoShadowStyle

is that available in coin? maybe we can add some bindings with pivy.

what source base of coin we use
here it is
https://github.com/Alexpux/Coin3D/blob/ ... wStyle.cpp

but to get shadows special hardware is required.

I will not devolop something for special hardware becausemostusershave default computers.
