If you can create an orthogonal frame by two vectors (i.e. find three points orthogonal to each other) you can create an orient attribute. inverting orient attribute and rotating @P by this inverse orient gets you world rotation

Hi,
very interesting results in this topic. I'm also waiting for threadripper gen 3 to update my pc and will be on windows platform. I'm sure things will get better by that time but wonder if you had time to check coreprio (https://bitsum.com/portfolio/coreprio/)
maybe it can improve your render times

what I usually do is:
to create a new orient with euler angles just start with an identity matrix
matrix m = qconvert(p@orient); vector zaxis = set(m.zx, m.zy, m.zz); vector yaxis = set(m.yx, m.yy, m.yz); vector xaxis = set(m.xx, m.xy, m.xz); float amount = radians(degrees); rotate(matrix, amount , xaxis //chose any axis ); p@orient = quaternion(m);

Hi,
I'm trying to write my own volumetric glsl shader but dont know how to sample grids -density temperature etc-. I've gone through all samples at houlib/glsl but I think im missing it.

Afanasy does distributed simulation. check out the original repository (https://github.com/CGRU/cgru) or mine (https://github.com/sergeneren/cgru) as i have placed a couple more options on otl. But be reminded mine is way behind original.

In the attribwrangle the attribute name should be “strength”, not “Strength”.

thanks for the fast feedback. that's the downside of being a noob.

Hi everyone,
I have a simple problem when altering the glue strength inside a sop solver with attribwrangle. In the attached file, if you switch to sop solver inside dops (switch is in sop level) glue doesn't get updated. however it updates in sop level. No big problem but i just wanna find out why.
Any ideas? and thanks.
