ogre assertion (!q.isNaN())

[Aperion]

has any one else been getting the following error when attempting to run RoR from latest SVN?

RoR: /home/chris/dev/ogre/OgreMain/src/OgreNode.cpp:393: virtual void Ogre::Node::setOrientation(const Ogre::Quaternion&): Assertion `!q.isNaN() && "Invalid orientation supplied as parameter"' failed.

it seams to happen when OGRE is starting to render frames.

I'm not sure where this would occur, if it a problem with our code then it's not use calling setOrientation, it happens after many many calls through ogre, including renderframe.

yes, i am experiencing this error as well, and i was not able to fix it yet :-/

we need to look through the changes list from 1.6.x to 1.7 maybe

ok, I wanted to make sure it wasn't my configuration.

BTW I have every item in the list for CMake compiled into RoR at this point. I will probably work on merging the win32 and linux methods together so there is less code to maintain. Minus paged, I'm

good to hear
i am releasing a new PG version soon hopefully that will be used then.

are you working from a separate branch for the release? or is it just the latest version?

i am working on the "forests" trunk for that. Also see: http://redmine.rigsofrods.org/projects/pagedgeometry

fixed a problem related to entities under windows, is the problem still existing?

not sure yet, the latest changes to cmake pretty much hosed all of my changes to the CMake system for linux.

Edit: Nope, no such luck, I still get the assertion error. Any idea what's causing it?
Edit2: a little more digging reveals that the problem node appears to be the "PlayerCam" node it's values are getting messed up some where.

*BUMP*

Found the culprit, or at least the place that is causing the Quaternion to go to NAN

it's this line of code in ExampleFrameListener.cpp:5846

mCamera->setOrientation(spl.rot);

I'm not sure WHY or if this code has changed but spl.rot is Quaternion::ZERO. I will look at it more after I go plant a grapefruit tree and pull otu a stump, and another tree. and plant a pear tree.


Edit: commenting out this line seems to fix the problem.

fixing this in the trunk, thanks!

please try to use redmine, that speeds up a lot of things

yes yes I appologize. I found it a little while ago and because it was only one line I totally forgot about it until jtbo mentioned it, so I quickly added it here. I have more stuff I need to submit to redmine.

thanks for debugging RoR again

i just have too little time to test everything it seems
