How to take current view and set the view to orthographic?
I tried using viewer.getCamera() to get parameters how the view is currently set and then setting it with viewer.applyCamera().
var camera = viewer.getCamera();
console.log('Camera: ' + JSON.stringify(camera));
Which returns:
Camera: {
"metadata": {"version":4.3,"type":"Object","generator":"ObjectExporter"},
"object":{"uuid":"78D2EA86-853B-473F-9E0E-E3F0C8874E40",
"type":"Camera",
"matrix":[1,0,0,0,0,1,0.00009999999747378752,0,0,-0.00009999999747378752,1,0,114010.796875,88329.0078125,135503.609375,1],
"children":[
{"uuid":"53C7FA49-B00C-4616-9E7A-CCB94A661A45",
"type":"DirectionalLight",
"color":8355711,"intensity":0,
"matrix":1,0,0,0,0,1,0,0,0,0,1,0,-0.5,0.20000000298023224,0.05999999865889549,1]},
{
"uuid":"7D5EC244-7268-4190-8480-4BD1DD56F8CB",
"type":"Object3D","matrix":[1,0,0,0,0,1,0,0,0,0,1,0,0,0,0,1]
}]}}
Then I tried setting, with the "matrix" array as params, but the view jumps.
viewer.setViewFromArray(params);
I followed the format of an array with the data from current camera and applied them by viewer.setViewFromArray. I kept all other parameters, but only set the last param to 1 (ortho).It looks working well at my side.
viewerApp.myCurrentViewer.setViewFromArray([
viewerApp.myCurrentViewer.getCamera().position.x,
viewerApp.myCurrentViewer.getCamera().position.y,
viewerApp.myCurrentViewer.getCamera().position.z,
viewerApp.myCurrentViewer.getCamera().target.x,
viewerApp.myCurrentViewer.getCamera().target.y,
viewerApp.myCurrentViewer.getCamera().target.z,
viewerApp.myCurrentViewer.getCamera().up.x,
viewerApp.myCurrentViewer.getCamera().up.y,
viewerApp.myCurrentViewer.getCamera().up.z,
viewerApp.myCurrentViewer.getCamera().aspect,
viewerApp.myCurrentViewer.getCamera().fov,
1,
1
]);
you can also check the source Viewer3D.js to get the workflow how setViewFromArray works.
Viewer3D.prototype.setViewFromArray = function(params, name){....}
IF you simply want to switch the view between perspective and orthographic, you can use the direct API:
Viewer.navigation.toOrthographic()
Viewer.navigation.toPerspective()

I'm trying to figure out a way to build a progress bar with React. I have a forEach loop that iterates through an array of about 7,000 indexes. Each time I validate a row, I want to update a state variable with percentage completion (and render this on the page live). I've tried iterating through these indexes, and updating my state variable (hoping to update the page) in the loop but I'm realizing that will not work. I obviously can't do this with a normal variable as it will reset when the component re-renders. Can anyone give me some insight on this topic?
Thanks.
Here is a code snippet from what I'm looking at:
parsedAssets.forEach(asset => {
newAssetValidated = validateBulkUpload(asset, parsedAssets, assetList, accountLogged, jobSites);
!newAssetValidated.reject_err ? validatedAssetList.accepted.push(newAssetValidated) : validatedAssetList.rejected.push(newAssetValidated);
setStateAssets({ ...stateAssets, validatedAssetList });
});
}
So essentially, as each asset is either accepted or rejected we add it to "stateAssets", and I'm hoping to build the progress bar from the length of the combined arrays that are getting set in stateAssets. However, when the forEach loop is completed, only the last validated asset is getting set due to it not updating until the forEach loop is completed.
Personally I can't imagine such a heavy validation, that you need progress-bar, but anyway.
First solution is to separate validation itself from state update for progress-bar into separate "threads". But since JS is single threaded, you may use some tricks with setTimeout or setInterval functionality. It may be very tricky, and in general not recommended practice with React.
Another way is - to set the work into queue & process 1 item at a time.
As an example I would do it something like this:
function ComponentWithProgress({parsedAssets, setParsedAssets}) {
const [validatedAssetList, setValidatedAssetList] = useState([])
const [progress, setProgress] = useState(0)
const [toDo, setToDo] = useState([])
if(parsedAssets && parsedAssets.length>0) {
setToDo(parsedAssets)
// clear parsedAssets in parent component to: [], false, null ...
// so you put it into toDo only once
setParsedAssets([])
}
if(toDo.length > 0) {
const asset = toDo[0]
const newToDo = toDo.slice(1) // All but 0th element
const newAssetValidated = validateBulkUpload(asset);
setValidatedAssetList([ ...validatedAssetList, newAssetValidated ]);
setToDo(newToDo)
setProgress( newToDo.length / ( validatedAssetList.length + newToDo.length ) * 100 )
}
// ... Render here
// If you need only accepted
const accepted = validatedAssetList.filter(v => !v.reject_err)
}
This example maybe not work for you as is, because you didn't showed us the context, but the main idea is here.
I am currently porting an UWP application from C++/CX to C++/WinRT. I encountered a safe_cast<Platform::IBoxArray<byte>^>(data) where data is of type Windows::Foundation::IInspectable ^.
I know that the safe_cast is represented by the as<T> method, and I know there are functions for boxing (winrt::box_value) and unboxing (winrt::unbox_value) in WinRT/C++.
However, I need to know the equivalent of Platform::IBoxArray in order to perform the cast (QueryInterface). According to https://learn.microsoft.com/de-de/cpp/cppcx/platform-iboxarray-interface?view=vs-2017, IBoxArray is the C++/CX equivalent of Windows::Foundation::IReferenceArray, but there is no winrt::Windows::Foundation::IReferenceArray...
Update for nackground: What I am trying to achieve is retrieving the view transform attached by the HoloLens to every Media Foundation sample from its camera. My code is based on https://github.com/Microsoft/HoloLensForCV, and I got really everything working except for this last step. The problem is located around this piece of code:
static const GUID MF_EXTENSION_VIEW_TRANSFORM = {
0x4e251fa4, 0x830f, 0x4770, 0x85, 0x9a, 0x4b, 0x8d, 0x99, 0xaa, 0x80, 0x9b
};
// ...
// In the event handler, which receives const winrt::Windows::Media::Capture::Frames::MediaFrameReader& sender:
auto frame = sender.TryAcquireLatestFrame();
// ...
if (frame.Properties().HasKey(MF_EXTENSION_VIEW_TRANSFORM)) {
auto /* IInspectable */ userData = frame.Properties().Lookup(MF_EXTENSION_VIEW_TRANSFORM);
// Now I would have to do the following:
// auto userBytes = safe_cast<Platform::IBoxArray<Byte> ^>(userData)->Value;
//viewTransform = *reinterpret_cast<float4x4 *>(userBytes.Data);
}
I'm also working on porting some code from HoloLensForCV to C++/WinRT. I came up with the following solution for a very similar case (but not the exact same line of code you ask about):
auto user_data = source.Info().Properties().Lookup(c_MF_MT_USER_DATA); // type documented as 'array of bytes'
auto source_name = user_data.as<Windows::Foundation::IReferenceArray<std::uint8_t>>(); // Trial and error to get the right specialization of IReferenceArray
winrt::com_array<std::uint8_t> arr;
source_name.GetUInt8Array(arr);
winrt::hstring source_name_str{ reinterpret_cast<wchar_t*>(arr.data()) };
Specifically, you can replace the safe_cast with .as<Windows::Foundation::IReferenceArray<std::uint8_t> for a boxed array of bytes. Then, I suspect doing the same cast as me (except to float4x4* instead of wchar_t*) will work for you.
The /ZW flag is not required for my example above.
I can't believe that actually worked, but using information from https://learn.microsoft.com/de-de/windows/uwp/cpp-and-winrt-apis/interop-winrt-cx, I came up with the following solution:
Enable "Consume Windows Runtime Extension" via /ZW and use the following conversion:
auto abi = reinterpret_cast<Platform::Object ^>(winrt::get_abi(userData));
auto userBytes = safe_cast<Platform::IBoxArray<byte> ^>(abi)->Value;
viewTransform = *reinterpret_cast<float4x4 *>(userBytes->Data);
Unfortunately, the solution has the drawback of generating
warning C4447: 'main' signature found without threading model. Consider using 'int main(Platform::Array^ args)'.
But for now, I can live with it ...
I am trying to generate an output as a random number using Postman so that I can PUT it onto a 'thing' in my IoT app
If I give the value in the following format, it works correctly:
{
"WindSpeed" : "88"
}
But now I want to pass on the value of the "WindSpeed" in an automated manner (something like using the random value function) so that I don't have to manually change it every time,
Unfortunately, I am not able to do so as I have trying ways available online including setting global variables etc. etc. but it is always giving an error of 'BAD STRING' or that the JSON content does not have 'ValidProperties' etc. I think that maybe my syntax is wrong. Could someone please guide me as to how I can generate random values in postman(syntax etc.)?
but why not just to use
postman.setEnvironmentVariable("random_list_name", _.random(1,
10000000))
Where "random_list_name" Environment Variable
This is simple and seems does the same
You shall generate your random value in the prescript tab using a function like this one:
// random generator function
function getRandomInt(min, max) {
min = Math.ceil(min);
max = Math.floor(max);
return Math.floor(Math.random() * (max - min)) + min;
}
// generate the random value
const myval = getRandomInt(0,100);
// set the value into the global variable
pm.globals.set('value', myval);
// to see it in console
console.log(myval);
Then, in your JSON body, you shall use it:
{
"Windspeed":{{value}}
}
This should work.
I have this foreach function, but I need to add a where clause.
I have added a checkboxlist in Umbraco called "show"
Values if this is
"EN"
"SP"
"US"
...
Let us say I have checked EN and SP.
I only want a slide to be visible if the slide is Visible as now, and if the field show are "EN" is checked and true. How can i add this in my code?
#foreach (var Slider in Umbraco.ContentSingleAtXPath("//HomePage/SliderArea").Children.Where("Visible").OrderBy("CreateDate
desc").Take(4))
The code you have is using Dynamics and therefore you're restricted to using the pseudo-Linq extensions like .Where("Visible"). You'll find it much easier to manipulate the list of items if you use the Typed objects instead.
Change this:
// Returns IPublishedContent as dynamic
Umbraco.ContentSingleAtXPath("//HomePage/SliderArea")
to this:
// Returns fully typed IPublishedContent
Umbraco.TypedContentSingleAtXPath("//HomePage/SliderArea")
Then you'll be able to use the full power of Linq to do this:
var area = Umbraco.TypedContentSingleAtXPath("//HomePage/SliderArea");
// returns a filtered IEnumerable<IPublishedContent>
var sliders = area.Children.Where(c => c.IsVisible() && c.GetPropertyValue<string>("show") == "EN");
#foreach (IPublishedContent slider in sliders.OrderByDescending(c => c.CreateDate).Take(4))
{
// You can get the dynamic equivalent of the IPublishedContent like this if you wish:
dynamic dSlider = slider.AsDynamic();
// ...
}
I'm trying to create a flash application that will keep track of user generated values. The app should basically allow the user to input the name of the item and it's cost. The total costs should then be added up to show a total value to the user. I can probably figure out how to add the values together, but I'm not really sure how to allow the user to create a list and then allow the user to save it. Can anyone point me towards a tutorial or point me in the right direction?
I am using variables to add user inputed numbers to come up with a total. The first problem is that actionscript 3.0 does not allow variables for texts. I just converted it to 2.0 to fix this. The second problem, is when I test the app and put in my values and click submit, I get NaN in the total values field. Is there a reason why it wouldn't add the values?
Here is the code I used for the submit button:
on (release) {
total = Number(rent) + Number(food) + Number(travel) + Number(entertainment) + Number(bills);
}
Am I missing anything?
Can I give the input text instance names and then give them variables? How are some ways to go about this?
Thanks for the help!
Have an object array, say for example
var stack:Array = new Array();
Then push the item name and it's cost to that array when user inputs, like
stack.push({item:AAA, cost:xx});
So that you can generate the list whenever you want with that array.
You have to see how this works in code. A list in actionscript could be stored inside an array, vector, dictionary or even an Object.
Var myList:Array = [];
myList.push({name: "item 1", cost: 5 });
myList.push({name: "item 2", cost: 7.5 });
If you want to grab the 'product' of "item 1" from the list, you have to create a function for that, lets call it getProductByName
function getProductByName(name:String):Object
{
for each(var product:Object in myList)
{
if (product.name === name) return product;
}
return null; // no match found
}
You can call that function like this:
var product = getProductByName("item 1");
trace(product.cost); // 5
And you can alter the product, so lets make it more expensive
product.cost += 1;
trace(product.cost); // 6
Have fun! If you are using classes, you would create one for the product, with public name and cost, and in that case you'de better use a vector, to ensure working with the right type.
This is what fixed the issue for me in action script 3.0:
myButton.addEventListener(MouseEvent.CLICK, addThem);
function addThem(e:MouseEvent)
{
totalField.text = String ( Number(field1.text) + Number(field2.text) + ....);
}
I also had to name the instances appropriately.
