Importing and animating MDL files in Game Maker

[SVT2002]

Hello!
I'm wondering,that how can i load and ANIMATE mdl or mdx model in Game Maker game creation software.I tried to make it myself,i can load mdl models,but the animations are too big task for me.Bezier,hermite,quaternion...i don't know,how to write algorithms for things like that.If anyone here tried to make somthing like that,please give a download link!

Sorry for grammatical problems.

Thanks

All the algorithms are standard algorithms either explained in Wikipedia or other websites around the internet. For example Bezier.

I've tried to make an animating system,but in hermite translation algorithms I'm not sure.And quaternion rotations are also complex.I can rotate a bone vector correctly, but as i tried to rotate more bones, they move abnormal. I don't find the problem. And a question:if i tried to rotate a group of vertices connected to a bone,I rotate them around the endpoint of the Parent bone of the rotation bone,or not?

Thanks

Quaternions and curves are quite simple, you just need to read a little.
You can also check stuff in the 3D viewer's source, granted it's outdated and in Javascript (most of the stuff you'd need is in the math and handlers/mdx directories).
If you are afraid of curves for now, just force linear interpolations.

Can't help you with code, since you didn't post any, but the general gist of skeletal animation is that you start with a root (nodes with an object ID of -1 in Warcraft 3), transform it according to your frame of animation, then go to its children, transform them according to your frame of animation and then also by the parent, and so on, recursively.
When every node has its final transformation (world matrix), you use it to transform attached vertices.
Here's pseudo code assuming everything is stored in standard 4x4 matrices.

Transformation = Parent * (Translation * Rotation * Scale)

The final position of any vertex is divided by the amount of nodes that affect it.
For example, is you have some vertex V that is attached to two bones, B1 and B2, then the pseudo code will be as follows:

Position = (B1*V + B2*V) / 2

All BLP textures are in linear RGB color space. This means that you do not need to convert them for use in the shaders (more specifically they are not loaded as sRGB textures) but you will need HDR or gamma correction afterwards so the results look correct.

Modelling and texturing goes perfect.The problem was the animation.
