anyway in mathemathics to define 3d trajectories in a walking animation? i reckon it should be straightforward simple?

like how it should feel like it has weight, speed, so on

One of the essential skills in computer programming is the ability to write descriptions which are easy to understand. Do you have that skill?

@previous (B) this isnt computer programming
> easy to understand
you look at all those simulation papers and explain to me what they wrote then.

clearly it's not as simple as a kindergarten children will get

@previous (itsallkidshereanyway)

I'm talking about your post. It's not understandable.

anyone else did. but ok lets rephrase.

i want to know how the trajectory in animal locomotion happens, like how the legs came to position itself in the entire 12 frames of the animation, the xyz/3d trajectories of it, of every single bones of the creatures, which allows the movement/locomotion to happen

i imagined the position is factored by momentum and inertia and variables like weight, speed and conditions, but otherwise i couldnt understand how exactly the limbs locates and rotates to create the locomotion

Have you tried doing this on paper before doing it on a program?

> paper
YES, Finally someone understand. not like 4aggotchan,i mean ehem ok good
> before programing
well the key is trying to understand the mathemathics on paper so i can simulate the 3d trajectories as i draw it before going to code it

as of now i dont even know what to "program" since i dont know how to get the correct coordinates

i thought it should be simpler since i dont ask for codes

Can't you just start off with a paper calculation? Use 4 limbs with no joints (ie knees), and see if you can do that. Then add knees. Something to consider is that the muscles will have different movement rates (degrees per cycle).

thats what ive been saying. i dont know how to do the paper calculation so i need some pointers.

@626,650 (C)
i imagined it s simple enough of a trajectory model, but i dont know how to do it

Give me 24 hours to do something simple.

....anything easier/whatever you have would be better.
but yeah go ahead
