The Parallax Measurer tool in 3DMasterKit that may be rarely used, but is very useful. Here is an example of printing lenticular images, which we recently completed.

Lenticular printing of bookmarks and magnets for the Museum of the World Ocean, Kaliningrad.

Lenticular: 75 LPI 3D.
The number of frames: 64.
Size: 75×75 mm

The Parallax Measurer tool in 3DMasterKit helped a lot in this project. This tool allows to accurately measure the disparities between objects in a 3D scene. These relative offsets are different for foreground and background objects and are called parallaxes (foreground parallax, background parallax).
These parallaxes determine the strength of the 3D effect on the lenticular image.

Parallaxes can be measured in various ways, for example, as a % ratio to the width of an image. This indicator is useful when the size of the print is unknown at the modeling stage. However, experienced printers can also tell the recommended parallax in physical quantities (in mm). This value is determined based on the experience of printing on specific materials and equipment. Victor from Stereograd.su informed of the optimal parallaxes for the lenticular lenses 75 lpi and the print equipment. Thus I made the layout exactly according to his recommendations.

The “Parallax measurer” in 3DMasterKit shows values in both % and mm.
In order to use the tool, you need to do the following.
1. Set the physical size of the future product in the settings of the “Cropping frame”.
2. Generate a test series of frames and select the first and last frames. Set a semi-transparent overlay mode.
3. Use the Parallax Measurer tool to find the disparity of objects (click on the left edge of the object, swipe along to the right edge and release).

In my case, Victor, the printmaster from Stereograd, informed me that it is better to place the text with a parallax of about 1.5 mm, the parallax of the background can be 15-20 mm, the parallax of the foreground 10-15 mm.

By specifying the distance for the layers (on the Z-axis) and the rendering settings (Background parallax, Foreground Parallax), I have selected the parameters that provide the desired offsets (note that a depth map has also been added for the planet).

Additionally, 3DMasterKit allows to create an animated preview and save it as a video file.

The result is great. Excellent 3D effect and high quality.

Thank you to Victor and the Stereograd team for their work!
