Re: Natural Motion

Yup. Just press the 'bone' button in the lower-right-hand corner of the window (see attached image.) The red dots in the middle of the platform show the 'target' bone positions, while the blue dots show the points from each convex hull rigidbody (independent of the graphical mesh.) But hmm.. sorry, ...

Re: Natural Motion

Well, my guess is that it's because I don't really understand how constraints work. As it stands, it loads the model, and each vertex that has greater than a certain weight on a bone (50% at the moment) is added to a convex hull body. Then, a 6dof constraint is created at the joint in the bones, att...

Re: Natural Motion

After some experimentation with a few other computers it seems that the solution is to install the visual C++ 2008 redistributable package. (it's just a few .dll's, 1.8mb) http://www.microsoft.com/downloads/details.aspx?FamilyID=9b2da534-3e03-4391-8a4d-074b9f2bc1bf&displaylang=en Also, here is the n...

Natural Motion

Okay, a long time ago I was trying to make a way to integrate cal3d and bullet to make a sort of naturalmotion-style effect, where a character will act out its animations but also be affected by physics. I implemented it using an algorithm found here: http://graphics.cs.williams.edu/papers/DynamoVGS...

Re: limit a character

Just by attaching a constraint, I don't think so. For not falling down sharp cliffs, yes, an invisible wall is probably your best bet.

Re: Angular velocities

I'm not sure if y'all have a preferred file hosting service, so I googled Free File Hosting...I can put it somewhere else if you prefer: (Win32 .exe + necessary .dll's and data) http://www.mediafire.com/?8tnjzm9ecy1 This is a poorly-hacked version of the Cally Demo, which is the generic demoapp for ...

Re: Angular velocities

Shoot..I sort of did a write-up at home but I'm at school now :P didn't expect a response so quickly.. Basically, I am implementing this design: http://graphics.cs.williams.edu/papers/DynamoVGS06/ since it didn't seem that they had created a general-use, open-source library...at least not one distri...

Re: Angular velocities

I tried putting setlinearvelocity values using the crossproduct of the angular velocity of the parent bone with the position offset; this causes the character to 'explode' >.< but if I only use 1/3 of it or so, the animations seem a lot more fluid than without...the only problem is, unless I anchor ...

Re: How to change friction on a rigidbody

I don't know what kind of editor you're using, but personally I just use MSVC's 'go to definition' and 'find all references' features.. barring that, the header files are pretty clean and straightforward. I gave up on the doxygen a while ago :P

Angular velocities

I'm putting together a physics overlay for the Cal3D character animation library (or one could say, a cal3d wrapper for bullet :P) and it's working pretty amazingly well, considering how many things have gone wrong so far, but there is one more problem I need to address before I can say it's working...
