Dot motion depth

Hello Jaewon & community,

I am curious if random dot motion will ever support a Z-axis for movement. I understand that this might be difficult, but I don't believe a possible implementation currently exists.

PsyT has the moglDrawDots3D function, but my team already uses ML2 extensively and would rather stick with it.

I appreciate any tips you might have.

Can you describe what kind of stimulus you want to present? The function you mentioned is implemented by exposing 3D APIs, which I think just makes things complicated for most people. If what you want is a simple 3D effect, we don't need 3D APIs. Try the attached example. Turn on the mouse input or the simulation mode.

Update: The example is included in the package now. See the "task\runtime v2\30 optical flow" directory.

Thank you Jaewon for the examples. We will take a closer look at them.
To answer your question, we are interested in creating circular and radial pattern of random dots, as shown in the attached image. These pattern is also called optical flow. We wonder how we can easily generate these in the framework of ml2. Much appreciated!
best,
Haoran

There are more examples in the new package. See the "task\runtime v2\30 optical flow" directory. You can do many things with imagination and a little bit of math.

Thank you, Jaewon. These adapters were clear and served their purposes. We did update them to interface better with properties such as DotColor.
