Picture bounding box

[JGoode]

Hello,

is it possible to remove the bounding box lines that are visible in 3D when using a 'Picture'?

Thanks

As far as I know the 'Picture' command when used in 3D does not have a boundary (unless the image you are using has one).

It will have a background though so it will always be rectangular.
But if your image has and Alpha channel, you can hide the background.
You can control the visibility of the Alpha channel with the 'mask' option in the PICTURE command.

Hi,

Please see my attached image.

My code is this:

picture "male_wc", A, ZZYZX, 1

It's not a huge problem, but ideally it wouldn't show in 3D.

Thanks

I see what you mean.
I don't have the man image but I grabbed one that does have an Alpha channel.

The background is transparent but the image border is still there.


I am not sure how to turn that off.

The best I could do was to set a white pen colour just before the PICTURE command.

I use the EXTRUDE command directly, the thickness is 0, and the edges are hidden.
