Hi Steven,
thanks for reply.
I tryed to add shadows on my scene copying the osgShadow demo example. When I
cleanbuild the project, the make returns an error... I don't understand why.
Can you help me?
Here is the code I added to my project:
Code:
int ReceivesShadowTraversalMask = 0x1;
Hi Wojtek,
thank you for reply and suggestions.

I was supposing this, and of course I need to change the make file.

HI Wojtek,
thank you very much, your suggestion helped me a lot! Now the shadow works
properly in my app.
For who may have my same problem (I'm sure nobody is newbie as me), the
solution was to add the line:

to CMakeModules/FindOSG.cmake file

I just need to add shadows to my simple virtual room. I understood that have to

add to the the shadowdScene the children. Then, I can set to each children (en

Hi,
I finished my application and I want to improve it. I have to issues: I need to
increase the frame rate, since I rotate fast the camera and I need to start the
simulation window at fullscreen (for now, I have to fix the dimensions
manually).
How can I do this?
Thank you!

Hi Jean-Sebastien,
thanks for the reply, you were realy helpful, now I have a better idea on how

Hi Sergey,
really thanks for your help.

Hi,
Basically what you need to do is translate rod to (0,0,0), apply rotation
that u need, and translate back to original position.
If your math is right and you still haven't expected results i'd say that
your model has static

thanks a lot for your answer!

In the step where you're calculating m, it looks like you're applying the
rotation to the original matrix, which includes a translation already.
Yes, this is (perhap) what i want. I try to be less ambiguous: my scene is a

Hi,
i'm trying to rotate a rod (part of a 3rd party model) on its Y asxis. I read
on OSG Startguide that to do it, i need to find the correct position of my
object from the origin and apply a multiplication like T * M * -T.
The source code that tries to do it is the follow

I understood part of the issue, and thus I corrected (part of) the error. Now
seems that the rotation and the translation is formally right, but visually
translation is wrong. I enclosed 3 pics of the scene, before rotating, after
1st rotation and after 2nd rotation. I correct the source as
Hi /ulrich,
thanks for your answer. i've found the solution... i've restarted Netbeans :-\
I don't know why, but it hadn't save/update the source files, so the make
continued to work with the wrong code sources.
However, now the rotations is applied, even if as not expected... (it changes
I've tryed this same eventHandler on a simple graph containg:

geode rotates...
could my issues depend on the imported model?

Thanks for the advice, you have been enlightening.

Hi,
I've created my scene, and now I need to move camera in it, using keyboard.
My idea is to handle camera using some key lik A, S, W, D to perform

Hi,
i've an issue with my application. How kind of unit is used by osg for length?
Can i configure it?
Moreover, between lighting techniques supported by osg, is there also a global

Hi Torben,
thanks for your answer. I imagined it, but when i loaded the cow model in my

Hi all,
for completeness i share here a site [ยน] that allows to convert sketchup models
into 3ds, obj and other formats. I found and tried it yesterday evening and
sees to work well.
I hope this post can help those who had my own doubts and problems.
Thanks again to all, best regards,

Thank you all for your suggestions, since i had so many problems
building/installing collada-dom i decide to convert sketchup model in the 3ds
format which is loadable by osg.
I had already installed osgBullet to obtain physics... on next coming days i'll
study how to use those libraries :-)
For completeness, i point out this site [1] which allow to convert sketchup
files into 3ds, obj and other formats.
I hope this post can help those who have my own doubts and problems.
