zoomout will cause part of model hidding

[flower4wine]

Hello Masters,

I tried viewer and it's awesome !

However, I encounter a visual problem: while zooming out, a model will be hidden by part. If I zoom in, the missing part will show up again. Anything I need to pay attention? Like camera settings, near/far clip, or any other stuff? Thanks a lot !

Last but not least, thank you much for this project.

Best Regards,
David Tan

Hi David

Glad to hear that you are happy with the vA3C Viewer.

The issue you describe most likely relates to the PerspectiveCamera.far
variable. See:

http://mrdoob.github.io/three.js/docs/#Reference/Cameras/PerspectiveCamera

Currently this variable is set manually in the default template file:

https://github.com/va3c/viewer/blob/gh-pages/va3c-viewer-html5/r6/template-basic.html#L28

If there are issues, you can call the Zoom Extents function by clicking on
its icon at the bottom of the menu. Here is the function:

https://github.com/va3c/viewer/blob/gh-pages/va3c-viewer-html5/r6/jath-three.js#L108-152

This function resets the camera near and far distances according to the
size of the data in the drawing.

Because the function has to examine every single object in the drawing, it
is kind of 'expensive'. But we should look into doing this automatically if
the drawing is not too large.

I will add such a feature to the Read Map.

Thank you for the feedback.

Any other issues? Or wishlist items?

Theo

Hi Theo,

Many thanks for your so quick reply!

I'm working on revit2.html, instead of the HTML5 version you mentioned. Anyway, I get it done by change far distance from 10000 to 50000. Cheers! :-)
