Hi, I want to find highlight points\vertex when mouse cursor hovers geometry. I find few example link http://3dhop.net/examples/demos/8.0_measurement_tool.php?title=Measurement%20Tool [Mohit] Measure distance between points of STL file using three.js javascript, three.…

Hey, Its Amazing, Thanks :yum: I Have one more doubt , In that your code the marker ( SphereBufferGeometry ) size depend on size of .stl model. Can we fix it for all .stl model? I want to find distance between two highlight vertex.

You can set the radius of the marker to 1 then scale it in proportion, for example, 0.025 of the longest side of bounding box of a model. [image] Nilesh: I want to find distance between two highlight vertex. Any explanatory picture of the desired result? Or more detailed explanation?

file5.stl (6.7 KB) Please add this file to your code. you will get result.

That’s how you can scale the marker in dependence of the max dimension of a model: https://jsfiddle.net/prisoner849/1wnsf4b7/

Thanks, I used that ,i got error ,not able to solve that :expressionless: Uncaught TypeError: tri.getBarycoord is not a function ** at setPos** Can you suggest me?

Hello, able to solve that problem. thanks :yum:

Hey, Can we add some geometry( box) on that highlighted a vertex after mouse click event on that point (onDocumentMouseDown)? like this https://threejs.org/examples/?q=inter#webgl_interactive_voxelpainter

I see no single reason why we can’t :slight_smile: Create a box mesh, put it at some position that is surely never happen to be in the camera frustum at the beginning (kind of box.position.setScalar(10000)) then on a mouse down event just change the position of the box with copying the position of …

Hey, Its Working . Actually i want to calculate distance between two point which is got after on mouse down event on two highlights vertex at once in scene. In my scene i loaded .stl file. i used this ,yet not implement. [Mohit] Measure distance between points of STL file…
