Click an object marked with a line?

[aldin_abdagic]

Hi
In a blender, each click object is marked with a yellow line surrounding the model.

Is this option available in babylon.js, or any other option?
Any idea?

Oh Aldin, are YOU back again? You sure are a work-aholic.

Obviously, the best way to show that a mesh “is-selected”… is to squirt colorful particles from its vertices… https://www.babylonjs-playground.com/#2A4NUR#29

Ok, ok, that’s just a joke.

Here’s a link to search the old forum for ‘mesh is selected’. The 2nd return is the most interesting, where I list a few ways to indicate isSelected.

Inside my comment… does #3 in the list… look familiar? Remember our private project, with the pulsating emissiveColor? Fun, huh?

I am talking about showing when an object is selected, but that’s not your precise question, today. For what you seek, the outline-render might be the best. https://www.babylonjs-playground.com/#JY0TT#1

I think this uses the outlineRenderer, but a docs and playground search for 'outlineRenderer" or a docs search for ‘outline’… has weak returns. You’ll need to dig-deep to get more info (old forum search?).

Let’s see… umm… glows, highlights, perhaps outlines… COULD have depth-sorting anomalies (weirdness) because they might be post-processes… sort of a last-minute cellophane sheet with paint on it… placed across the mostly-rendered scene. Such things can act strangely when a highlight/glow is in-front-of SOME things, and behind other things (depth sorting).

If you remember our private project, we started with using highlightLayer, but ran into depth-sorting problems. Then we changed to pulsating emissiveColor. Anyway, have fun! I hope I have been helpful.

This is great
Just like in a blender …
I remember the previous model marking example. This will leave for later tools. Outline color selected model is present in all 3d programs, so it looks more professional …
I succeeded by clicking on the model to put the green outline on the model, but clicking another model remains outline on the first clicked model?

Hi AA. Hey, the green outlines look GREAT, and no sign of depth-sorting problems. Perhaps outline feature is NOT a post-process “layer”… like glowLayer and highlighLayer are? We should research how it is done, someday.

If outline were a type of layer, it would probably be named outlineLayer, eh? But it is not - good good good. I’m glad it is working nicely.

I removed lines 104-106. Remember myMeshesOne/Two/Three are “arrays of meshes”… so renderOutline property is ignored… when set on an array-type object.

You would need to loop thru each array, and change eachmesh.renderOutline = false;
OR you could loop-thru scene.meshes, and change each-mesh THAT way.

Look at line 96. If there already WAS a selectedMesh, turn-off its outline. Works ok.

Remember that myMeshesOne/Two/Three… are arrays. They must be for-looped-thru… to access each mesh within.

You might wish to code some HELPER functions… such as:

var setPropertyOnEachItemOfArray = function(some_array_name, property_name, what_value)
{ code }

You know layerMasks, now, so you might make another helper…

var setPropertyOnEachItemOfLayer = function(some_layer, property_name, what_value)
{ code } This will be a bit more complicated… but a useful tool.

Looping tools - for doing things to each member of a group-of-mesh. Hunter-gatherer-tag-and-release helpers.

Just some ideas for the future.
