Translook Content：
Principle: Make the proportions, shadows, floor, lighting, depth, viewing angles, etc. of the two-dimensional video consistent with those of the three-dimensional box.
To better explain how to deconstruct a 2D video to create a 3D holographic image, please refer to the following illustrations.
For digital production settings, we strive to base everything on the actual settings. Therefore, we take the physical production settings as the starting point.
We use an 85-millimeter lens (rotated vertically) on a full-frame camera.
If the object we are creating is abnormally deep on the Z-axis and needs to be compressed, then increase the lens to 115 millimeters!
The negative space around a character or object helps to visually place that item within the Translook device. Anything that squeezes the edges of the frame will destroy the 3D effect and make the image flat.
Playing a full-screen video will completely eliminate the 3D effect and turn the Translook into a large vertical digital signage.
The characteristics of the transparent liquid crystal display will cause white to be completely transparent (similar to wearing a green shirt on a green screen). To solve this problem, we use colored or gradient backgrounds to turn the transparent areas into negative space so that the white areas look the same as they were designed. Colored backgrounds will make it seem that the backlight LED lights inside the box have taken on that color.
In terms of lighting, we use large, diffused, off-axis light sources to cast shadows behind the materials. This is the key to any object inside the box. However, we combine the shadows with other lights to bring objects/animations to life. HDR maps, edge lights, and solid objects for reflection can all help you achieve objects such as jewelry that require reflection to look realistic.
If the object/subject interacts with the floor plane, adding reflections between the subject and the camera helps to fix the object in the Z-depth (and enhance the illusion).
Depth of field (DOF) should not be used because we are trying to mimic the visual effects in real life.
These are our general starting guidelines that can be followed, bent, or broken, depending on what works best for the creative production.
