CrossHair Tool : Cannot access 'center' before initialization about cornerstone3d HOT 16 CLOSED

I tried that example and it worked locally now
Based on your error it is complaining that the init on crosshairs has not been called, which is called on active, passive, enabled modes. Maybe put a debugger at init and debug line by line to see if the toolCenter is calculated

@Celian-abd Which example are you trying to run?

from cornerstone3d.

I am trying the crossHairs one.

https://github.com/cornerstonejs/cornerstone3D-beta/blob/main/packages/tools/examples/crossHairs/index.ts

from cornerstone3d.

When I log my crosshairtool object in the console I can see the toolCenter with coordinates that are the same as my image center coordinates.

from cornerstone3d.

So does it actually get inside the init function? Can you provide the source code you are using?

from cornerstone3d.

So here you have the main code where I create the toolgroup and add it all the tools : https://github.com/Pixilib/Dat_Scan_Viewer/blob/main/datscan/src/components/ViewerVolumeRoot.js#L100

And here is my component where I activate the CrossHair : https://github.com/Pixilib/Dat_Scan_Viewer/blob/main/datscan/src/components/tools/coordsOnCursor.js#L247

from cornerstone3d.

you should do the toolInit before adding tools https://github.com/Pixilib/Dat_Scan_Viewer/blob/main/datscan/src/components/ViewerVolumeRoot.js#L107

from cornerstone3d.

Yes this was only a test, but initially the Toolinit was before adding tools and the error was the same.

from cornerstone3d.

I've updated my code
https://github.com/Pixilib/Dat_Scan_Viewer/blob/main/datscan/src/components/ViewerVolumeRoot.js#L99

Changing slice thickness with the crosshair is working but not rotating.

what is the recipe for running your app (project)?

from cornerstone3d.

Hi Alireza, it is a simple Create-React-App,
from the repository go to "datscan" folder and then npm install and npm start.

in the opening webpage you will have a drop zone to drop you dicom files to load them in the volume viewer.

thanks for you help,

Salim

@Celian-abd Is there any specific reason you are using the /dist/esm for the imports? The bundler should automatically use that and you don't need to directly import from each folder

from cornerstone3d.

@sedghi No specific reason, I was using a VS Code extension to automatically import but it was indeed a mistake. I just cleaned all the imports.

Code : https://github.com/Pixilib/Dat_Scan_Viewer/blob/main/datscan/src/components/ViewerVolumeRoot.js

Still did'nt find how to fix the rotation though.

from cornerstone3d.

I think you are not setToolEnable for crosshairs here https://github.com/Pixilib/Dat_Scan_Viewer/blob/main/datscan/src/components/ViewerVolumeRoot.js#L207

I have more time later in the week to run your code.
On a separate note, the createAndCache does not load the volume, it just allocated memory, so I don't think you should add your segmentation for

from cornerstone3d.

I've already tried to setToolEnable before setToolActive but the result is the same.

Solve with lastest version.
