Does anyone have any suggestions on how to make a hollowed out sphere or bowl shape using Adobe Dimensions or any other program that is compatible with Flash.

Take one sphere and place it into another and do a booleen aciton. that will give you the bowl you want. Regards, Bill

This is not meant to be a tutorial, just a list of high-level steps.

In 3D Studio MAX, create a sphere of radius 18 and 48 segments. In the hemisphere spinner, type in 0.5. Name this 'outerSphere.' Clone the first sphere and select 'copy,' not 'instance' or 'reference'. Name the copy 'innerSphere' and click on the Modifier tab. Change the radius to 17.

Select the outer sphere from either the front or top viewport. From the Create tab, click on 'Compound objects' and select Boolean.

The default operation is A-B and the outer sphere is already selected (the A object). Click on the 'Pick Operand B' button and click on the innerSphere object.

This will hollow the outer hemisphere as Bill suggested, leaving you with a bowl of one unit thickness. Collapse the stack to an editable mesh. Export to .3DS.

Import to Swift 3D and assign a material. Export with area shading and then import into Flash. Delete the first frame as required and export your movie. You might see something like

Go back into your MAX scene and apply a Normal modifier to the mesh. Click on Unify, then export. Import into Swift3D. It's not any better and depending on object orientation, it might be worse. Flipping normals does not help.

Now, repeat the process using spheres with 128 segments, instead of 48. It will take longer to import and render in Swift 3D.

Your final result (with area shading) might look like

File sizes:

Bowl - 48 segs : 3.6K
Bowl - 128 segs: 0.6K

If you want the .3DS files for the bowl, just send me e-mail. You can experiment in Swift or Vecta on your own. In Swift, you can experiment with adding more lights and changing orientation to get better results out of the lower-poly model.


have fun!

If you're using Dimensions, then just lathe a U shaped eps file., or actually I guess half a U... then it will make the bowl for you. It's actually quite simple in Dimensions.
