@Victor I just confirmed that in Astra SDK v0.4, with Astra Pro, if you run the SimpleStreamViewer-SFML sample, it will initially show just a blank window*. But if you then press ‘i’ to switch to infrared view, you should see it. You can look at the SimpleStreamViewer source code to see how it accesses infrared.
When coding this in your app, for both Astra SDK and OpenNI, make sure in your code to set the resolution of the infrared stream to 640x480 or 1280x1024.
- It is blank because it’s waiting for a matching color frame for the depth frames, and currently Astra Pro color isn’t supported with the SDK. If you run SimpleDepthViewer-SFML it will show Astra Pro depth.
