Hello;
Is there any node that computes the Acceleration attribute (something like Trail SOP -> Compute Velocity)?
Actually, in a particle simulation, I need that attribute.
Thanks for helping.
Hello!
New Houdini user here with barely 3 weeks in... so please bare with me
I'm trying to write a small VEX function/expression to translate an object along it's Y axis by an exponential function... like gravity.
The math behind is simple but I'm having trouble expressing it in VEX...
I tried the following line with a VEX attribute wrangle node on a default sphere and it's giving me errors and the sphere just disappears on the 1st frame: t.y = t.y + (9.8 * ($T ^ 2));
If someone could steer me in the right direction I would appreciate it thank you :-)
