Hi Guys,

I am doing a wiper motion using RBD.

I have given the Hinge constraint to support the arms and correspoiding Static and Rigid body Objects.

I would like to automatic RBD solver Wiper motion using constraints alone.

My Question:

1. Currently my Wiper does not touch the Windshield when it is in movement. How do I fix it?

2. I want to wiper end to always be in contact with the Windshield. How do I give this constraint.

I am attaching the hipnc and corresponding geometries here and two pictures showing my problem( No contact during wiper motion)

Further help would be much appreciated.

Thanks

Hi guys,

I would like to extract the position of a point following along a curve and its rotation along axis in a text/csv file using chops.

For example in the attached pic (View_1), we can see the position of the point on the curve and its corresponding global coordinates ( P,P,P ) at a particular frame.

Say, I want to export these positions of this point traveled along the curve and also the angle made with respect to each axis based on the normal of the point, frame by frame (Total frames 240 in my current case).

I need a final table like, For example

Frames P P P Angle Angle Angle
1 0 0 0 0 0 0
.
.
240 1 2 3 40 50 60

How do I implement in CHOPS.
And to export in csv or text file.


Please your help would be kindly useful.

I cannot access the houdini forums using the keyword search, as i am getting irreveleant material based on “AND” and “OR” wildcards.

Is there any way only to search the posts by title in HOUDINI Forums Search.

Million cheers

Hi,

I downloaded a tutorial file which changes the position of a point based on channel expression. (View 1)

In this tutorial there was already the parameter slider option named as ch(“value”). (View 2)

I am trying to create this similar slider using EDIT Parameter Interface (Pulldown Gear button in parameter window)

How do I do it?

I would also like to save the position of these points in an csv file format from frames 1-1000 based on these channel expressions.(View 3)

Can be done using CHOPS or any simple options avaliable?


Thanks
