1. Bvh File Converter

Pay per use or upgrade to a plan to get animations at. I found tons of good, free bvh files, but not so many bip. I don't need people to breakdance or kickflip, just. Free Full Length Movies and Free Movie Downloads Added Daily at Free Online. Watch The Dresden Files Online - Free TV Shows & Videos. The only free bvh library in the world. So a bunch of my characters are walking around with flat hands. There seems to be a limited number of decent BIP files. I found tons of good, free bvh files, but not so many bip. I don't need people to breakdance or kickflip, just walk, jog, talk on the phone, stand conversing, maybe laugh, do something.

Using GLFW3, I currently made a bvh file parser which reads the file in and converts it to a human model I made in opengl. However, whenever I launch it, the movement is so fast that the animation cannot be seen in the eye. So I want to tone the animation speed a little down. Here is my render loop

The function inside the if statement bvh.setMotionPerFrame(bvh.root, 0) is where the animation reads in the JOINT configurations per Frame data inside the file, and sets each joint's rotation matrix and translation matrix accordingly. (moveFlag and resetMatricesare flags that are set if spacebar and r button are hit respectively)

Since reading the channel data per frame in each render loop unchangeable, I want to come up with a way that I can slower the render loop speed itself. Any suggestions?

You need to add timing to your code. while you are parsing BVH MOTION like this:

you should extract the Frame Time value which is the time between frames in seconds. Now depending on the code architecture of yours you need to properly time your rendering. I am used to have some

telling whole app to redraw on next possible occasion (like timer) which is set by anything from mouse/keyboard events changing view or scene to resizing of window etc...

For time changing stuff I also usually have a function:

periodically called from app handling interpolation/simulation and stuff for dt time elapsed from last call. Now the dt can be timer interval that calls this or in case I need better accuracy I measure dt directly using windows PerformanceCounter. In case you just got endless loop you still can use:

which is not precise but will work.

More on animation and timing topic can be found in here and the sublinks:

Now getting back to BVH here is how my C++ update method for it looks like:

here some selected stuff from my BVH class:

And tper function measures time between its subsequent calls taken from my timing lib:

Now in main app loop/timer just call periodicaly the update and if _redraw is true set it to false and repaint your app. Beware my bvh::dt was converted to [ms] !!!

You're not using the actual file in the for loop. You're just using the same hardcoded path each time.

Maybe you want something like the below?

I renamed files to file_path to better represent what's in that variable. Then I used that value in the call to import_anim.bvh, and then I used it again in the call to export_anim.bvh. (There I tacked on '_exported.bvh' to the end of the file name. I wasn't really sure what you were trying to do.)

You are using files for both counting and holding the current file path in each iteration. And in the iteration you don't input the current file path to import_anim, you just used a hard coded file path.Also, ++ is not a valid syntax.
