Setting up to create spherical objects.

Most of the setting up to create spherical objects is done in the main dialog of PhotoToMesh:

Spherical mesh with offsets

Set the "Solid Shape" combo to be "Spherical Mesh". Then you can change all three dimensions of the sphere, they have all be set to 120 in the example above.

If any one of the 3 dimensions is different from the other 2 you end up with "oblate" spheres, which may be useful if you want a flattish but curved object, like a flat pebble for example:

Oblate Sphere Mesh

In the above case I've set the x diameter to 20, leaving y and height of meridian (z) the same, 120.

You can use the "Image Placement..." button to move the image around on the surface.

If you make y smaller than the other two dimensions then the image will be placed on the "sharp side" of the oblate sphere:

Oblate Sphere STL , the sharp end

Note how x and meridian are set to 120, while y is set to only 60.

The only other spherical setting you need to know about is whether the sphere is hollow or not. To set this click on the "Other Settings..." button, as shown below:

Hollow out a solid STL sphere

 

As an aside note that I've used vignette settings to smooth the edges of the rectangular photo.
