    I found a thread on "How to extract depth data in real time?"

    For me I would call it "stepping through the depth data". https://github.com/IntelRealSense/librealsense/issues/4026 There is an easy method in rs-depth.c but the thread admin mentions a better alt...

    Good. the decimation filter sub samples the depth table. Excellent. Thanks. It's in rs-post-processing. A nice program.  That's a better app then the depth quality tool for demonstrating the filters.

    I see. That makes sense. Good information. The filters are part of the sdk , demonstrated in rs-post-processing. The sub-sampling seems to be something I need to do myself(?). That explains the com...

    last post on this - the 3d distance code makes sense. It's uses the same get_distance function as in the link you posted. I was confused by the comments in the function. // Note: this can be optimi...

    Yeah, I played with that for fps and it worked nicely. I was more wondering what options I would even need to disable for depth only streams. I'll look into the options. Thanks a lot. Great support.

    Good, Thanks.  I do need X,Y and Z. The CUDA thread's OP mentioned aligned frames being a problem. I'm glad I don't have to worry about that. Thank you.

    It just occurred to me that since I'll never need a color stream, is there sensor functionality that I  can disable(?) in order to achieve efficiency?

    So I'm seeing that  using the depth_frame I don't need to  bother with the deprojection process in rs-measure. Is that right? I am NVIDIA so I'll also l look at the  CUDA support and try and figure...

    Is there alternate faster code available that measures the 3d distance? Is get_distance and rs2_deproject_pixel_to_point fast or should I be digging into the code? Thanks. // Query the frame for di...

    3. rs-tracking-and-depth example in the SDK poduces all black.

    Got it  thanks! I suppose the same with rs-trajectory. TYVM saved me lots of time.
