Dear PyGui 3D Preparations

[hoffstadt]

Future Plans

Everyone who has been following us since the beginning knows that our future plans include a real time 3D Engine for Dear PyGui. Part of the support for this includes a lot of planning and API decisions. Most the current API has been designed to work well in conjunction with 3D. One of the goals of Dear PyGui was to be cross-platform with practically no difference in user API between operating systems. We would like this to be true for the 3D engine aspect as well.

To better facilitate this goal, our we plan on switching the current default backends to run on Vulkan for Windows and Linux. We would also like to do this for macOS however Vulkan is not directly supported. There is MoltenVK to fix this but we haven't had a chance to work with it yet (it does look very promising though!). Although not ideal, we are not opposed to having macOS have an entirely different 3D API.

In order to not break the stability we've built up to this point, the current backends will not be removed (we will just call them legacy) and will be properly maintained.

New IM Module

There will be a new module added that will include a direct mapping to Dear ImGui and implot for those wanting an immediate mode interface when working with 3D. We haven't decided on a name yet for this module. Adding this would be trivial and require almost no work.

Dear Py3D

Dear Py3D will be the name of the 3D engine. It is being written in Vulkan and will require Dear PyGui to be using the Vulkan backend.

Experimental Module

While we toy around with the user API for Dear Py3D we will be using the experimental module in Dear PyGui for temporary testing. The temporary engine we are using for testing will just be for Windows and be using the current Directx 11 backend.

Initial Goals for 3D

• Model Viewer (simple usage, more like a widget used with DPG)
• Create 3D Scenes (lights, cameras, materials, etc.)

Early Prototype Gallery

These are some images of earlier prototypes of testing DPG, python, and simple 3D renderers we built for testing:

Waiting for it !!! 😄

@hoffstadt when will this come ??

[iOsnaaente]

Awesome!!
I already have plans to use it as soon as possible when it is available 🤩

[luisarandas]

Has this been released? :)

[hoffstadt]

Not yet. We are still toying around with prototyping!

[luisarandas]

Please share when you consider the time :)

Any updates ??

Hi,

Just read your announcement about DearPyGui 1/2.

Is Vulkan in any way relevant to DPG2?

Thanks,
Eli

@hoffstadt @Pcothren Does skia makes sense for 2D engine to make 2D GUI (The question is in context of your new project pilotlight). It is very popular and is used by chrome and flutter via dart https://github.com/google/skia
Vulkan based example https://github.com/google/skia/blob/main/example/VulkanBasic.cpp
Also the python bindings: https://github.com/kyamagu/skia-python

make python great again
I hope that it's easy as dpg

[spectereye]

Any info. for this? I see Dear Py3D had been deleted ...

[mushroomfire]

Why delete Py3D?

When you will release it?
