When you use a 2D image and a depth map to create a 3D mesh, you're generating the object's geometry. A mesh is made up of vertices (points in space), edges (lines connecting those points), and faces (flat surfaces created by the edges). It's like a wireframe skeleton that represents the shape or surface of the object, but it's usually hollow—essentially just a shell. It lacks the material properties and internal substance that would make it feel or behave like a real object. If you look inside a mesh, it would be empty because it has no internal structure. On the other hand, a 3D model goes beyond just geometry. A real solid 3D model has not only the shape but also the visual and physical characteristics that make it appear and act like a real object. It has thickness and volume, meaning it has mass and internal structure, so if you were to 3D print it, it wouldn't be just a hollow shell but a solid object with some substance inside.

zForm supports PNG and JPG file formats for both images and their corresponding depth maps.

While zForm is designed to run on most machines, the performance may vary based on your computer's hardware specifications, especially the CPU and RAM. For larger images or complex depth maps, more powerful hardware may improve performance.

Ensure that both the image and depth map were imported correctly and that they are compatible in size. Check the Blender console for error messages that may provide additional insights.

You can modify the Subdivision Level and Smooth Factor parameters in the zForm panel to enhance the quality and smoothness of the generated mesh.

Yes, once the mesh is generated, you can use Blender's modeling tools to make further adjustments, such as sculpting or modifying geometry.

You can use Blender's Undo feature (Ctrl + Z) to revert the last operation. Alternatively, you can save your work before using zForm to maintain a backup of your original scene.
