3D objects are drawn in special rendering programs such as Blender (free) or 3ds Max Design (Adobe, not free).
A 3D object is in effect a fine ‘polygon mesh’ that defines the three dimensional surfaces of the object, along with ‘texture maps’ to apply to the many individual polygons.
In addition, you can scan in an existing object and convert it automatically into a 3D object using just your iPhone. A popular iOS app for this is Poly.cam:
With the Polycam app, you simply use your iPhone to take many pictures of an object from all directions, then the cloud software generates an actual 3D object. This works well with highly textured objects that do not have ‘holes’ or shiny surfaces. These objects can be further edited in a rendering program.
Once you have created your 3D objects, you can export them into USDZ (Universal Scene Description standard) format for use in Driftscape. Not all 3D object features are supported yet, such as animation sequences. USDZ is in effect a single compressed file format for 3D objects that includes the texture files as well.
