Exclude from clipping plane

[Anonymous]

Hi guys,

I have a scene with an office building and a car in front of the building. I would like to use clipping plane only on the car, so I would like to exclude the building from the plane.

Does anyone know if this is possible?

Hi,

create a new clipping plane node an put the car inside of it.

this clipping plane will act only on the car.

Hello @Anonymous,

correct, as @Christian_Garimberti wrote, create a new clipping plane for the car. Please find more information about the clipping planes here:  Using the Clipping Plane

Hope this helps!

Best regards,

Patrick

Thanks Chris,

Thanks Patrick,

I have experimented with the way you mentioned about the put the clipping plane on top of the target folder. But I wonder, if I use coding to create the clipping plane:

enableClippingPlane(true)

Can I still add limitation to this clipping plane created by coding, or position this clipping onto the folder I want to clip by coding?

Thank you.

ClippingPlane is not the same thing of  ClipPlanes.

You have to create and manage CipPlanes.

You can get an already created clipplane with the findNode("<node name>")

i think you can use all the vrnodeptr methods and functions

Hi Yang,

creating a new ClipPlane node with Python:

clipPlane = createNode("ClipPlane")
updateScenegraph(True) # Scenegraph GUI refresh

Add your target node as a child to the clip plane node:

clippedGeo = findNode("MyGeo")
clipPlane.addChild(clippedGeo)

To enable the ClipPlane node (btw, it is already enabled by default):

findNode("ClipPlane").fields().setBool("on", True)

To change the transformation, either use the member functions of vrNodePtr, or use any of the setTransformNode... functions found in vrNodeUtils (e.g. setTransformNodeTranslation, setTransformNodeRotation).

findNode("ClipPlane").setTranslation(10, 20, 30)
# or
setTransformNodeTranslation(findNode("ClipPlane"), 10, 20, 30, False)

Hope this helps to get you started

Hello Sinje,

Thanks for the detailed explanation, it works perfect to what I would like to do, and it opens more possibilities for the experience.

Hi

With Clip Plane could we also rotate and show the clipping contours and grid visualisation ? 

Thanks

[Christian_Garimberti]

No, clipplanes are only to cut geos.

What you want to do, contours and grid, are features of the Clipping Plane tool.

ok thanks

Yes i came to know that cliplane and ClippingPlane ( from the gui ) are two different things

With clippingplane , the contours are visible which is very good functionality but unfortunately not available in clipplane

So clippingplane is good for the purpose but is there a way to let the clippingplane only cut the a specific model ? i.e it should not cut other object near the object of interest ( i experimented this with clipplane and this works but dont want to use clipplane as it doesnt  have the contours )

So if i can avoid cutting of unintended objects with clippling plane would be great

Thanks for the tips so far

Hi, There are no way to exclude objects from the clippingplane.

Unless you put them inside the Environment node... but i thing it is not a best practice...

You can add the request in the idea board if you want.
