How do i hide specific child node from rendered 3D model in android? - arcore

ANDROID ARCORE:
I want to hide specific child nodes of rendered 3D model?
Like we have hiding option in ARKIT by finding child nodes with names.

Calling removeChild(node) and addChild(node) causes flickering, so rather hide with node.renderable = null and then show with node.renderable = theNodeRenderable.

View and Geolocation fields

There is something wrong with my views and the way it's communicating with geolocation field. Firstly the map is not opening zoomed out so you can see all locations within the view which means I have to zoom out to see all the map markers.
Secondly, whenever the markers are hovered or clicked they don't show any relevant field data or links to the nodes of which the markers are related. I've tried every configuration that I can think of in views Format, Fields and Filter criteria and nothing seems to work.
My entity structure consists of Venues and Events. The Venue has the geolocation field which is entity referenced in the Event with inline_entity_form (complex). The view I'm working from is an Events view with a relationship to Venues. I've also tried putting a geolocation field directly in the Event entity and I still have the same problem.
Does anybody have a solution to these issues?

add attachment for your map and also separate page for the list of your fields.Also in the filter criteria exposed the boundary of you geolocation field.Enable ajax,it works for me.

Avoid moving the map with Overlays

Do you know how to avoid panning the map view when showing overlays with OpenLayers 3? I have a popup objects, displaying with hovers or click events. But I'd like to aovid the whole view to move, that can be quite disturbing with many "hover" popups which move the map to show this object...
I guess that will be with the change:position event of ol.Overlay, but what's the function to "block view pan" in this case ?

How to add a label and edit controls inside an already existing groupbox in a design mode using delphi

As one of my requirements, I have to add a label and edit field to an existing groupbox in delphi. But how many times, i add a label inside an existing groupbox it disappears or it wont get added. Is there an alternative way to do this?
Am not sure why but am able to add edit but not label
I'm going to take a wild guess here. You are adding new components without first selecting the group box in the design surface. When you do that the component becomes a child of the form and disappears beneath other controls.
Here's how to do it:
Click on the group box on the form design surface,
then double click on the label in the palette.
Alternatively:
Single click on the label in the palette,
then single click on the group box on the form design surface.
If you do get the component parent/child relationships messed up, you can inspect them in the Object TreeView (open this from the View menu). If the relationships are wrong, drag the child controls around in the Object TreeView, and drop them into their desired parents.

Movieclip: Attatching/Removing a Movieclip VS Hiding and Showing a Moveclip

I have this tool tip that is created every so often. What is the appropriate actionscript etiquite?
A. To Create and remove the tooltip moveclip when needed?
or
B. To hide and show the tooltip movieclip when needed?
With these A and B, the answer is B, because creating and then removing an object a lot of times creates a lot of garbage in the memory, which eventually leads to garbage collector calls, that slow your SWF's performance. You can easily go with a single tooltip MC, just fill it with information that corresponds to the new mouse coordinates before you show it.
There is another question, not so straightforward as yours, about how to hide and show a movie clip, either via visible property or via addChild() and removeChild() (AS3 only). If you are using AS2 or AS1, use visible property to hide and show your tooltip.
There are three ways to hide something in Actionscript : Alpha, visible and remove child.
Apha: If you turn the alpha zero the renderer always comes to this displayObject and renders it at alpha zero. So the object is always rendered you just cannot see it.
Visible == false In this case the object still exists in your displaylist. So the renderer comes to the object. Sees it's property is false and leaves it but it still exists in the display list.
removeChild This means that you're removing the object from the display list. This means that the renderer never had to even check for it. Which makes it the fastest option.
addChild doesn't take that much computing power as visible check. I'm sure you can find benchmarks on this.
If you don't have a lot of objects on yours screen and the tooltip is there every second I'd go with visible is false. In all other cases go with the third option.
On a side note, I've found it always easier to manage them with a toolTipManager. A class that makes sure that you have one tooltip on the screen because usually users only use one tooltip. So that makes things easier for me. I just always create the necessary tooltips and add them to the displaylist when required and remove them. (Not recreate them) At the same time have only one tooltip on stage.

Create multiple layers BlackBerry application

Do you know how to create a multiple layers BlackBerry applications
such as the Trapster, Poynt apps...
There will be a bottom layer displaying a map (users can interact with),
and upper layers containing buttons that user can click on.
There are two ways
use map field and add it with other controls on screen if you don't need to change data on map.
If you need to change data on map, like having markers override paint method. With some special cares.
