Hi,
I want to get the normal of whatever face the user clicked on.

I’m using:
_view.mousePicker = PickingType.RAYCAST_BEST_HIT;
_mesh.pickingCollider = PickingColliderType.PB_BEST_HIT;

The mouse event is firing I’m just not sure how to determine what face was clicked on… and subsequently the normal for that face.

Thanks!

Hey, the MouseEvent3D carries information about the normal. Have a look at the new picking tutorial.

The 3 last demos on the tutorial make use of the event’s normal property.

Thanks I hadn’t seen that tutorial. The last example is the most similar.

When I get the sceneNormal property from the MouseEvent3D instance its always one of the following:
(1, 0, 0)
(0, 0, 1)

This seems strange as my mesh is in the shape of a cylinder. I would expect to see normal values that have a decimal for both the x and z coordinates.

Is this correct… any ideas?

yeah, you are correct

can you try setting view.forceMouseMove = true?

Just tried it same result… no matter where I click on the model either the x or z value is 1 with the other values being 0 for the sceneNormal property.

What happens if you listen to mouse moves instead of mouse clicks?

Interesting… If I listen for move events with forceMouseMove=false I get the same result I’ve been getting however when forceMouseMove=true the move event’s sceneNormal property looks correct.

Seems like you’ve found a bug! Assuming that you are up to date with the lib, let me know what branch you are observing this in and I’ll fix it later today or early tomorrow.

Thanks!
I’m using away3d-core-fp11_4_0_9_gold.

I suppose for the time being I can record the sceneNormal value on mouseMove and then do what I want with it on click.

After you get the bug fixed do I go to github for the latest? Also will there be an updated swc with the fix?

Sure, thx for finding the bug! As soon as it’s fixed I’ll notify you here and leave instructions.

Alright, it should be fixed now, can you give it another try?

You’d need to update your away3d-core-fp11 library from github, in either the master branch or the dev branch.

Thanks!!!
I grabbed the latest code off of github and it looks like its working now. I really need a swc due to compile time. Could you post one?

I’m afraid I don’t have one. Can’t you just compile the library and use the outputted swc?
