TCL/Tk Script samples

[vgb777]

I recently downloaded Nebula Device 2 for Windows and DirectX. I seem to be unable to find some working TCL examples.

For example, I run NViewer.exe and try the following script (found on the internet at http://www.3dactionplanet.com/projectnomad/engine_faq.shtml).

sel /usr/scene

# create an ambient light
new nlightnode amb
sel amb
.setcolor 1.0 1.0 1.0 1.0
sel ..

# create a 3d node with mesh, texture and shader
new n3dnode pos
sel pos
new nmeshnode mesh
sel mesh
.setfilename "object.n3d"
sel ..
# -----------------------------------------------
# EOF
# -----------------------------------------------

The first sel command works, as does the creation and selection of the first light (amb). An attempt to set the color gives the error: "Object /usr/scene/amb doesn't accept command 'setcolor'".

Does this mean that I am missing a module (or package), or is this sample from a different version of Nebula?

I seem to be unable to find TCL/Tk samples for the Nebula Device 2. Can anyone help?

Thanks,

Sergey

for the script interface/command you may look here :
http://nebuladevice.cubik.org/documentation/nebula2/NebulaTwoScriptInterface.shtml

setcolor is simply not a function of nlightnode ! Look for
nscenenode::setvector3attr ; That the only function that might be used to set
the color of the light ( as done into mvieverapp.cc#272 )

for sample I'm not aware of any, but a n2 file - used to load 3d object - is in
fact a tcl script

For what I know ( therefore barely nothing... ) nebula is not a plain script
engine. In a point or other, you have to derive/create your own c++ classes.
nviewer/mviewer - as their name stand - are just 3d objects viewers.

The page you found refers to Nebula 1, not 2, so don't waste your time
trying to get any examples from there running.
