  1. Fluid-RBD interaction issue!

    Masoud replied to Masoud's topic in Effects

    Any Idea?

  2. RBD issue: How can I bring them to stop?

    Masoud replied to Masoud's topic in Effects

    Hi Atom, I want to use my custom collision object, so why a "groundplane" works fine, but my collision doesn't?

  3. FLIP-Fluid and a vellum interaction, how?

    Masoud replied to Masoud's topic in Effects

    Hmmm, OK, thanks.

  4. Fluid-RBD interaction issue!

    Masoud posted a topic in Effects

    Hello I would like to create a Fluid-RBD interaction. But as you can see in the image below, the fluid pushes the rigid body so strongly. I need the rigid body to be a little bit heavy and to float on the fluid, based on its mass attribute. (Decreasing the "Feedback Scale", didn't help). Thanks for helping. RBD-FLIP Interaction_01.hip

  6. Hi guys, How can I make an interaction between a FLIP-Fluid and a vellum object? Is it possible? Thanks for helping. FLIP and Vellum Interaction_01.hip
  7. Hello guys, In a simple RBD simulation, when I replace the "Ground Plane" collision DOP with my Collision-Box, the rigid body objects never stop moving! How can I bring them to stop? (When I use the "Ground Plane" node, everything is ok!). I tried to use the " rbdautofreeze DOP", but it doesn't work. Thanks for helping. RBDs_01.hip
  8. Hi Tesan, Than you. Yes, it works fine: vector4 q1 = quaternion(@N); vector4 q2 = dihedral(v@N, v@targetVector); vector4 quat = slerp( q1, q2, chf("bias")); v@N = qrotate(quat, v@N);
  9. Hi Konstantin; Thank you for the reply. Actually, I want to rotate scattered points' Normal to another direction (i.e. MyVector) using a blend amount. At first, I tried the lerp() function but instead of rotation, it blends them. Then I tried: float angle = chf("Angle"); vector4 rot = quaternion(radians(angle), v@myVector); v@N = qrotate(rot, @N); But it rotates the Normal around "My-Vector"! Here is an image of what I need: Rotate_Vector.hip
  10. Hello guys, Using VEX, how can I rotate a vector to another vector, by a blend value from zero to one (i.e 1=fully aligned, 0= not-aligned)? Thanks for helping.

  11. Houdini 19 Resample SOP issue...

    Masoud replied to Masoud's topic in General Houdini Questions

    Thank you Geoff.
  12. Hello, In Houdini 19, the "Resample SOP" isn't work as before when I set the "Treat Polygon As" to "Subdivision Curves"..! Is this a bug? Thanks for helping. Resample Curve.hip

  14. Hello guys, As you can see in the image below, in a bunch of points islands, I need these things, using VEX: 1) I want to apply random color to each point island (cluster). 2) I want to group each cluster’s (averaged) center points. I tried several ways without success . I would appreciate any ideas. Thanks for helping. Center_Of_Point_Clusters.hip
  15. Any idea?
  16. Hello guys, As you know, the default attribute value of "Density" in Flip-Fluid is 1000. Now, in a simulation with two amounts of "Densities" (e.g 1000 and 100), what is the best way to speed up the rising speed of low-density fluid particles? I want to force them to reach the fluid surface as fast as possible (maybe something like the buoyancy parameter, in the pyro solver). Thanks for helping.
