QUESTION
I'm pretty new to Swift, currently writing an AR game. Seems like my issue is very basic, but I can't figure it out.
I added a button to an AR Scene through the storyboard and linked it to an IBAction function (which works correctly when the button is clicked). I gave the button an image and deleted the Title. See how the button shows up in the storyboard: button in Xcode storyboard without Title
But when I run the app, the button image shows up with a default label (saying "Button") as shown in this image: button in iPhone screenshot WITH label next to the button image
I can't figure out why this label is there and how to remove it. Should I add the button programmatically instead of adding it through the storyboard? Should the button be treated differently because it's an AR app?
I was able to remove the label by adding the same UIButton as an IBOutlet and adding the following line in viewWillAppear:
...ANSWER
Answered 2021-Nov-23 at 21:07When Interface Builder isn't playing nice, I often open the Storyboard file in a text editor (I use Sublime Text) and edit it manually.
I had a similar issue - I had a button with an image, I had deleted the default "Button" title text in IB, which looked fine in Xcode, but when I ran it, the word "Button" was still there. So I found this line using Sublime Text and deleted it there:
QUESTION
In my JavaFX project I'm using a lot of shapes(for example 1 000 000) to represent geographic data (such as plot outlines, streets, etc.). They are stored in a group and sometimes I have to clear them (for example when I'm loading a new file with new geographic data). The problem: clearing / removing them takes a lot of time. So my idea was to remove the shapes in a separate thread which obviously doesn't work because of the JavaFX singlethread.
Here is a simplified code of what I'm trying to do:
HelloApplication.java
...ANSWER
Answered 2022-Feb-21 at 20:14The long execution time comes from the fact that each child of a Parent registers a listener with the disabled and treeVisible properties of that Parent. The way JavaFX is currently implemented, these listeners are stored in an array (i.e. a list structure). Adding the listeners is relatively low cost because the new listener is simply inserted at the end of the array, with an occasional resize of the array. However, when you remove a child from its Parent and the listeners are removed, the array needs to be linearly searched so that the correct listener is found and removed. This happens for each removed child individually.
So, when you clear the children list of the Group you are triggering 1,000,000 linear searches for both properties, resulting in a total of 2,000,000 linear searches. And to make things worse, the listener to be removed is either--depending on the order the children are removed--always at the end of the array, in which case there's 2,000,000 worst case linear searches, or always at the start of the array, in which case there's 2,000,000 best case linear searches, but where each individual removal results in all remaining elements having to be shifted over by one.
There are at least two solutions/workarounds:
Don't display 1,000,000 nodes. If you can, try to only display nodes for the data that can actually be seen by the user. For example, the virtualized controls such as
ListViewandTableViewonly display about 1-20 cells at any given time.Don't clear the children of the
Group. Instead, just replace the oldGroupwith a newGroup. If needed, you can prepare the newGroupin a background thread.Doing it that way, it took 3.5 seconds on my computer to create another
Groupwith 1,000,000 children and then replace the oldGroupwith the newGroup. However, there was still a bit of a lag spike due to all the new nodes that needed to be rendered at once.If you don't need to populate the new
Groupthen you don't even need a thread. In that case, the swap took about 0.27 seconds on my computer.
QUESTION
Thanks for taking the time to review my post. I hope that this post will not only yield results for myself but perhaps helps others too!
IntroductionCurrently I am working on a project involving pointclouds generated with photogrammetry. It consists of photos combined with laser scans. The software used in making the pointcloud is Reality Capture. Besides the pointcloud export one can export "Internal/External camera parameters" providing the ability of retrieving photos that are used to make up a certain 3D point in the pointcloud. Reality Capture isn't that well documented online and I have also posted in their forum regarding camera variables, perhaps it can be of use in solving the issue at hand?
Only a few variables listed in the camera parameters file are relevant (for now) in referencing camera positioning such as filename, x,y,alt for location, heading, pitch and roll as its rotation.
Currently the generated pointcloud is loaded into the browser compatible THREE.JS viewer after which the camera parameters .csv file is loaded and for each known photo a 'PerspectiveCamera' is spawned with a green cube. An example is shown below:
The challengeAs a matter of fact you might already know what the issue might be based on the previous image (or the title of this post of course ;P) Just in case you might not have spotted it, the direction of the cameras is all wrong. Let me visualize it for you with shabby self-drawn vectors that rudimentary show in what direction it should be facing (Marked in red) and how it is currently vectored (green).
Row 37, DJI_0176.jpg is the most right camera with a red reference line row 38 is 177 etc. The last picture (Row 48 is DJI_189.jpg) and corresponds with the most left image of the clustured images (as I didn't draw the other two camera references within the image above I did not include the others).
When you copy the data below into an Excel sheet it should display correctly ^^
...ANSWER
Answered 2022-Jan-02 at 22:26At first glance, I see three possibilities:
It's hard to see where the issue is without showing how you're using the
createCamera()method. You could be swappingpitchwithheadingor something like that. In Three.js, heading is rotation around the Y-axis, pitch around X-axis, and roll around Z-axis.Secondly, do you know in what order the
heading, pitch, rollmeasurements were taken by your sensor? That will affect the way in which you initiate yourTHREE.Euler(xRad, yRad, zRad, 'XYZ'), since the order in which to apply rotations could also be'YZX', 'ZXY', 'XZY', 'YXZ' or 'ZYX'.Finally, you have to think "What does
heading: 0mean to the sensor?" It could mean different things between real-world and Three.js coordinate system. A camera with no rotation in Three.js is looking straight down towards-Zaxis, but your sensor might have it pointing towards+Z, or+X, etc.
I added a demo below, I think this is what you needed from the screenshots. Notice I multiplied pitch * -1 so the cameras "Look down", and added +180 to the heading so they're pointing in the right... heading.
QUESTION
So with c++ 20 we get a lot of new features with ranges, spans and so on. Now if i need to iterate over a container, but only the first n elements, what would be the most appropriate way and is there any practical difference going on behind the scenes? Or is it perhaps a better idea to just go back to regular for loops with indexes as these examples might be less performant?
ANSWER
Answered 2021-Dec-17 at 01:17views::takeis the most generic, it is suitable for almost any range, such asinput_range,output_range, and more refined ranges.std::spanonly applies tocontiguous_range.Although
ranges::subrangeis also generic, but since you need to obtain the bound of iterator throughelements.begin() + n, this requires that theelementsmust be arandom_access_range.
It is also worth noting that after P1739, views::take will get an "appropriate" range type according to the type of range, that is, when the range is span, it will return span, and when it is string_view, it will return string_view, and when it is subrange, it will return subrange, and when it is iota_view, it will return iota_view.

QUESTION
I would like to set the saturation of an entire color channel in my main camera. The closest option that I've found was the Hue vs. Sat(uration) Grading Curve. In the background of the scene is a palm tree that is colored teal. I want the green level of the tree to still show. Same with the top of the grass in the foreground, It's closer to yellow than green, but I'd still want to see the little bit of green value that it has.
I have been searching the Unity documentation and the asset store for a possible 3rd party shader for weeks, but have come up empty handed. My current result is the best I could come up with, any help would be greatly appreciated. Thank you
SOLVED -by check-marked answer. Just wanted to share what the results look like for anyone in the future who stumbles across this issue. Compare the above screenshot, where the palm tree in the background and the grass tops in the foreground are just black and white, to the after screenshot below. Full control in the scene of RGB saturation!
...ANSWER
Answered 2021-Dec-05 at 13:45My best guess would be to use a custom shader or camera FX that would gives you control over each channel.
Hope that helped ;)
QUESTION
I have nodes that I can move, these nodes are placed on the Pane, which is on the ScrollPane.When I drag a node outside of the viewportBounds of the scrollPane, the vvalue should change so that the node is again within those bounds. To solve it I tried to use answers from this question.
My problem is that after the node is again within the boundaries of the viewportBounds, the cursor moves relative to the node, if I want to continue moving the node outside the viewport, after several iterations the cursor will move so much that it will be outside the entire application window and will rest against the screen boundaries. How do I maintain position of cursor on the node?
If you want to test code, keep in mind that the restructuring of the viewport boundaries occurs only when you move nodes along the Y axis.
ANSWER
Answered 2021-Nov-19 at 06:01To answer your question:
How do I maintain position of cursor on the node?
You need to use the AWT Robot class to move the cursor.

QUESTION
I am quite new to Julia. I am currently working on a small program, which requires me to plot a dot and remove it later (there will only be one dot at every time). I am using the the Makie package to visualize everything, but I haven't found a way to delete a dot, which has been drawn by scatter (or scatter!). The code should look something like this:
...ANSWER
Answered 2021-Nov-14 at 05:15What I've used in the past to erase part of a scatter plot is to redraw the dots using the background color (white is the default I believe). If you have several layers on the plot, you may need to redraw the ones you want to keep, though, since the overwriting may erase other features if present underneath:
julia> scene = scatter([0],[0], color="blue", markersize=10)
julia> scene = scatter([0],[0], color="white", markersize=10)
QUESTION
We're planning to expand our software to the South East Asia region. Our self-hosted Mongo Cluster is fully set up at China's AWS Data Center. How can we set up the MongoDB replicate set to AWS Singapore and allow writing on both regions and rely on MongoDB for asynchronously sync up data behind the scenes?
...ANSWER
Answered 2021-Nov-13 at 20:18What you are trying to do is not possible with MongoDB replica set. If you checkout the documentation here:
A replica set contains several data bearing nodes and optionally one arbiter node. Of the data bearing nodes, one and only one member is deemed the primary node, while the other nodes are deemed secondary nodes
If you really want to be able to do write operations on more than one server, you will need to shard your collections. You can go through the documentation here to get started.
