Hi guys,
as usual i have a question. How am i supposed to use the settings parallax and separation for the anaglyph glasses. What do the numerical values represent?
Also, is there a way to export the separate channels from this image (red and cyan)?
thanks
no one? not even pascal?
There are two numerical inputs, so modifying those might be a good idea to “use the settings”.
The Rhino help file is kind of lacking with documentation for those parameters. In general, if you have no idea, what a specific parameter does, either experiment or just leave it.
For what it’s worth, you might find some answers in this article here. Rhinos separation parameter is a factor, that modifies the virtual eye distance, parallax is probably the parameter, that defines the distance of convergence. It’s likely, a value of 1.0 will produce a reasonable image for the scene camera focal distance and an average human eye distance.
@jeff - Can you help here?
@Jakub - I don’t believe there is a way to export the separate color channels.
It doesn’t work that way… There is no red-channel or cyan-channel… An anaglyph is produced by merging two different images together into one. In Rhino, those two images are produced by rendering the scene twice from two different viewpoints based on separation and parallax settings, then the two rendered images are merged into one and displayed in the viewport. A red/cyan anaglyph is then produced by taking the red-channel from the left eye and combining it with the green and blue channels of the right eye, forming a new RGB value (so I guess you could look at those as the red-channel and cyan-channel, but all they really are fully rendered images from two different viewpoints). Producing other types of anaglyphs is just a matter of combining the correct r,g,b channels…so there is never really a left red channel and right cyan channel…there are just two full RGB images…and depending on what the settings are in the display mode, their components are extracted and combined to form a new RGB component and thus a new image.
That being said, perhaps it would be better to understand what it is you’re actually wanting to do here… Suppose there were two different channels, then what? What are you planning on doing with them? If I knew that, I’m guessing I could probably whip up a plugin example that does it for you…I can certainly come up with a way to export the left eye image where only the Red component is used, and then export the right eye where only the Green and Blue components are used…but what do you want to do with them after that?

Separation = Interaxial distance, the distance between the camera apertures. This relates closely to IPD (Interpupillary distance). Typically set to the average IPD, which is about 2.5" or 65mm
Parallax = The angle between the camera axes, is dominant in determining how far away objects look
