added the amcharts.client.ts plugin like this:
import * as am5 from '#amcharts/amcharts5'
import * as am5xy from '#amcharts/amcharts5/xy'
import * as am5radar from '#amcharts/amcharts5/radar'
import * as am5stock from '#amcharts/amcharts5/stock'
import am5themes_Animated from '#amcharts/amcharts5/themes/Animated'
export default defineNuxtPlugin(() => {
return {
provide: {
am5,
am5xy,
am5radar,
am5stock,
am5themes_Animated,
},
}
})
and other charts have worked, so I am fairly certain that the setup is correct.
For those interested:
I had amCharts5 set set up for transpiling in the NuxtConfig file. Removing it resolved the error.
I've got a very trivial task to drag&drop the element from a gallery into the Three.js canvas.
Nothing seems tricky until I face the problem that when I drag the item and add it to the scene I cannot update the item's coordinates until I finish the drag&drop event
I already played around with all events that watch the mouse event mousemove, drag, dragover but the element is just stuck at the initial coordinates, the ones I applied in the dragenter event

I am trying to create a scene with react-three/fiber and react-three/drei. I want to use a PerspectiveCamera and be able to pan/zoom/rotate with the mouse, but I am also trying to add some buttons that can update the camera position and target in order to have different views (eg. top view, bottom view, side view, etc). I have achieved the latter part and my buttons seem to be working as I update the target x,y,z and position x,y,z using props.
The only problem is that the camera is not responding to the mouse so I only get a fixed camera position and target.
I have included all the scene codes below.

I want to create a draggable / resizable / rotatable component in Ionic2.pan and pinch events are working great, but rotate has a strange behaviour: if I touch the component with two fingers, but without doing any kind of rotation, I will still get a rotation number around 15 to 30 deg, making the component rotate. I don't know if it is a known issue or something to do with the sensitivity of the screen. The code I am using for the component is this:

When I'm taking an photo with my Windows Phone the landscape mode, it's perfect. The problem occurs when I'm taking a photo in portrait mode.
The photo gets rotated 90 degrees. It even occurs in the simulator as shown below.
Now this doesn't occur on Android or iOS so I assume this is because Windows is using the CameraProxy.js instead of/from cordova-plugin-camera.

Does anyone know how I can keep my image rotation in Windows?
In your CameraProxy.js make changes in orientationToRotation function line number 569.
case Windows.Devices.Sensors.SimpleOrientation.notRotated:
if (cameraDirection == 0) {
return Windows.Media.Capture.VideoRotation.clockwise90Degrees;
}
else {
return Windows.Media.Capture.VideoRotation.clockwise270Degrees;
}
