Get mouse x,y,z location other an with an Inputpoint?

Yea - Alt is Window' global hotkey to activate the menubar of the active window.

yes it is... but it also has the move on to extra plane and allow new faces to be created function. when I hit alt while querrying it hold the purple marker where ever I leave it and stays at a specific two coords. since one coord is already known I took it.

That is not a design by the tool - it's a side-effect from Windows sending the focus to the menubar. Don't think it behaves like this on OSX.

It is a cool side effect, but it is not quite what I am looking for though anyhow. Because the query tool is still snapping to edges more than I wish it was. I'll just implement the InputPoint 3d position method, and wait until they hopefully fix the pickray for version8. Thank guys,

But, yes, you can shoot a ray:

` ray = view.pickray(x, y)
result = model.ray_test( ray )

TODO: Recast on hidden entities`

I have been using this method quite successfully but it does not work well if there is an 'out-of-context' face between the camera and the user's mouse position. This is even more of a problem if the user has 'Component Edit->Hide Rest of Model' The new raytest flag in SU8 that is supposed to ignore hidden geometry is not effective in this case. IMO it should also work for this situation.

Chris Fullmer

Could you test if the hit entity is in the current context, and just ignore it if it is not? That seems like it might be a solid workaround? Though I suppose that might be overkill because in many cases the user will not have 'Hide Rest of Model' turned on. So in those cases, you might want the user to be able to pick points outside the current context....hhmmmm.

I have not looked too much into this yet, but is there a way to get the 3d position of the cursor other than using an inputpoint? I was wondering if casting a ray would work. Does that return a point3d object? If I go that route, do I need to sort through what objects are or are not hidden/visible? Also, if it matters, I am only concerned about 3d points on a face. So if the mouse is hovering over nothing, I do not need to determine a 3d point for that. Just returning "nil" in that scenario is fine.

Chris,

I typically use a combination of InputPoint, to get the (x, y) in 2D and the face, and then view.Pickrayto intersect with the face and find the 3D point.

This is more or less what I have used in FreeHand On Surface, in particular to get rid of the inferences.

You can test that thru the RenderingOptions hash's InactiveHidden and InstanceHidden attributes.

Well there you have it! Glad you can test if they have Hide Rest of Model on or off. I had my doubts about truly being able to come up with a flawless solution to get 3dpoints from the cursor while ignoring inferencing, but this thread seems to indicate that its possible. I'll have to re-write my app I was making while I started this thread, because it currently just ignores the mouseclick anytime it gets inferred onto an edge. Very good, my little plugin might finally be useful

Just be aware that Scene (Pages) can also have their own RendingOptions hash instance.
