DepthAI V3 update

Hello,

Do you plan to update the depthAI SDK to V3 to enable use of the new OAK V4 range directly in TD ?

Yes, we’ve already spent quite a bit of time on the update, however there are still some issues with the new SDK. We’ll get it into the 2025 versions once things stabilize.

Hey @ben !
Do you know when the new SDK will be updated? Have you seen the new “host node” introduced by Luxonis? It’s mostly used to facilitate the previz of the video and data feed, but it’s also used for specific processing on the host side, like the OC-SORT tracker. I don’t know how extensively they plan to use it. Do you have any plans for them? I’m not sure how they could fit into TD.

Hello!

I have a working branch with DepthAI V3 SDK that supports the new RVC4 cameras. However we are still working out the best way to integrate the new features (such as the host node you mentioned) into Touch. There is also a fair amount of changes / backward compatibility issues between v2 and v3 that will break older projects using the OAK Device CHOP. @snaut can also chime in on future plans as well.

Hello @sazanbas

We are still in the planning stages of integration with DepthV3. The previous build mentioned was experimental and not the direction we are planning to go unfortunately. I will be sure to come back and respond to this thread and provide updates when we make further progress with Depth V3.

Thanks for your patience,

Huck

Hi Huck,

Thanks for the update.

We are very interested in the DepthV3 integration and need to understand how to move forward.

Could you please clarify the following:
Estimated timeline: when do you plan to start working on the integration and when is the expected release?

Technical requirements for the integration (API, data formats, limitations, etc.)

Will an SDK be available for DepthV3? If yes, when and what features/capabilities will it have?

This information is critical for our planning, so I would greatly appreciate a detailed response as soon as possible.

Thanks!

@sazanbas perhaps good to know that if this is required for your project, Derivative offers Pro Support which does include adding SDKs, libraries, and protocols not currently supported in TouchDesigner.

nettoyeur,

I purchased an OAK-4-D Pro camera and am trying to connect it in TouchDesigner 2025.32820. The camera is not working because DepthAI V3 is not yet supported.

@sazanbas @Huck, when do you plan to add support for DepthV3? Are there any estimated timelines?

Hello, I managed to wire depthai v3 in TD. Here’s the code: GitHub - SimonVandernest/RCV4-in-TouchDesigner: Support for depthAI v3 in TouchDesigner · GitHub . CUDA 13.2 is required, it runs stereo SGBM on your gpu. It’s rough around the edges, but I figured you could enjoy it anyways. You need to start the server through TD UI when installed (installer in GitHub releases)

Tested on TD 2025.32820, Win11, OAK 4 D Pro Wide
