ZofzPCB 3D Gerbers and Drills View
ZofzPCB 3D Gerber Viewer

ZofzPCB:
3D Gerber Viewer + 3D IPC-2581 Viewer

The free part of the freemium.


What is the difference, beside the 3D-iness?

Missing Information in Gerber files set

In 2D Gerber viewer you load gerbers and maybe also drills, in any order. They will have assigned arbitrary colors, to distinguish them. Possibly you can also rotate the z-order, bringing to front the layer you are interested in, at the moment.

To construct a 3D model, the viewer needs to know much more. As the abstract thought and knowledge of a CAM operator is hard to program, the user have to add or correct the missing information:

ZofzPCB tries to retrieve or guess this information, sometimes incorrectly. Therefore, it is always possible to correct the "Auto" loaded data, before rendering. It is a good practice to save the configuration in the .camset file. It will be easier to load the files, next time, after editing.

The IPC-2581

The new format solves all the problems listed above. It is also easier to remove the meta labels and frames, as the board outline is clearly defined.

Rendering

We are using a GPU (Graphic Processing Unit) via Direct3D, to display the image. Drawn/painted layer contains many overlapped objects. Often a part of the PCB plane is cleared, and some other elements are drawn in the resulting hole, like a track in a plane. All this higher level construct must be converted to optimal positive mesh. The result is that even a complicated PCB can be displayed by moderate GPU, usually at 60fps.

Drawback of the flattening and triangulation is the time it takes, before passing the mesh to the GPU.

Trangulated Planes

Animation

The rendering speed allows to animate the displayed components, creating unique impressions of rotation, movement, spreading and stripping layers of the PCB.

The approach lets you keep the frame of reference - it is clear where you are, what had happened to create a particular view.
