Hello. I'm sorry for my terrible english, but what pappers is your engine based on? Or is it fully your invention? I've heard that it uses some kind positionbased alghorithms, and Verlet integrator, but I'm not sure. Where could I read about technnical side of your engine?
Thanks.

In fact, I rarely read some papers although I collected many, what I read a lot is physics books and mathmatics books.
I don't think it's a matter what type of integration you use, I use simple Euler methed to do integration. Trimesh preprocess and collision detection is my own invention so you can not find any information in any papers. The solver I used in SPE is more like a constraint method, but I use a different form and I've done a lot modifications. I believe impulsebased, constraintbased or positionbased are the same things in mathmatics while solving rigid body dynamics, but I just know a little about positionbased method and maybe it is helpful while simulating clothes things.
Thanks.

does SPE handle very large terrain meshes well? (600k to 10M tris) what sort of broadphase is used?

I just test 500*500(500k triangles) terrain and it works well. I\'ll optimize it to handle 1000*1000(2M triangles) terrain without performance reduction in the next release. I use a special spacial grid to accerate broad phase. Thanks.

Hi, is it possible to get a bodys rotation in a euler vector ?

Euler angle is not supported directly by SPE at present, you need to convert it yourself after you get the rotation matrix.

is it me or is sdk download corupted ?
downloaded like five times with no luck.

Can you download Demo successfully? You can try to use a download manager to get it.

Can we adjust the simulation accurancy to promote computation efficiency?
The fact is that games do not need accurate simulation. And detail of presentation of objects far from camera is hardly sensed.

No this functionality at present, but objects far from camera is in fact often be static which need not computation. Thanks
