When i am doing my animation i take the inverse bind matrix that I am given and multiply it by the animation for the bone, by the bind shape matrix by the vertex by the world view projection matrix. If I use the matrix that I get from the inv_bind_matrix source, the meshControllerMatrix, I don't get anything in my viewer. However, if I just take the inverse of the bone given by the node specification in the visual scene branch, then I do get animation but it seems to be scaled wrong. instead of staying in place and rotating on the x axis, it swings about a translation in the same general direction but moves all over the place. When I use the inv_bind_matrix though nothing shows up. Can I be missing a step? ]]> Design Discussions alecto http://collada.org/public_forum/showthread.php/1658-Can-t-use-the-Inverse-Bind-Matrix-correctly http://collada.org/public_forum/showthread.php/1657-Sampling-in-COLLADA-objects?goto=newpost Tue, 21 May 2013 07:14:48 GMT Hi all, Basic problem is that I need to sample on the 1D curves (in 3D space), 2D surfaces (in 3D space) or 3D volumes specified in COLLADA.... Hi all,

Basic problem is that I need to sample on the 1D curves (in 3D space), 2D surfaces (in 3D space) or 3D volumes specified in COLLADA. Mathematically it leads to the mapping, e.g., of the 3D surface to the 2D limited plane (XY). So that by choosing point x in [0,1] and y in [0,1] we could get a unique point on the surface. The same stands for arbitrary 1D curves in 3D space and searching for a function that maps an arbitrary curve to the interval [0,1].

I would be grateful for any hints or suggestions. Please excuse me, if the question has no relation to this forum.

I'm sorry if I'm posting in the wrong area. I am using Maya 2008 to create a 3d tree with hanging fruit and leaves. There is animation throughout, including falling fruit. I'm at my last resort trying to figure out why/how to export everything in the scene fully. I have all the animation baked in, and streamlined, and named. All of the objects and animation export correctly except the falling fruit. After hours of googling, I've noticed a lot of people are having the same issue. It's very frustrating as I need this for an in-ap animation. Any help would be appreciated!

PS: another issue many were having with "flickering" animation - I figured out. It happens when you have your scene at 30/fps, and importing puts it at 24/fps. ]]> Implementation Discussions Uniquecharacter http://collada.org/public_forum/showthread.php/1656-Issue-exporting-from-maya-2008 http://collada.org/public_forum/showthread.php/1655-Linux-64-bit-Linking-colladadom-with-shared-boost-version-1-52?goto=newpost Thu, 16 May 2013 12:54:54 GMT When i link colladadom against boost 1.52 it errors out with lack of -fPIC for the boost static *.a libraries.

Help please, I have win XP SP2 32bit and running 3D Max9, I went to this site;

https://github.com/KhronosGroup/Open...nCOLLADA-Tools

And downloaded the 3rd one down from the top right for OpenCOLLADA for 3ds Max 32bit and now when I start max I get a;

DLL failed to initialize.
Error code:1114 - A dynamic library (DLL) initialization routine failed.

when I click ok max starts but I get no Open COLLADA export option.

I been on the net looking for some help by putting in the error but no joy, thought I might find the DLL needed.

I did a test, when I take the Open COLLADA DLE out of plugins MAX start up with no errors, so its the Open COLLADA DLE some where just not sure where yet.

I hope some one can help me here.
Thank you.

What exactly is the best way to export my models out of Maya to use them in Assimp? I figured out how to export the model with a baked animation (I use FBX_DAE Export in 2013), but how can I get multiple animations for one model (e.g. a character)? I've read that it can be done with clips but I couldn't figure out how to do it.
I wanted to test the OpenCollada Plugin but just crashes for me, no matter what I do.

Do you have any tips?

I have a collada file in my project with extension .dae In IIS 7 I set MIME type: model/vnd.collada+xml for .dae extension. I also set anonymous authentication to true. Now I have some problems displaying this collada model. Some user are not able to display model. What is quite interesting they are not able to display it in mozilla, but in explorer they don't have those problems. Others are not able to display it in Explorer, so there is no dependence.
