3D Experiment: Red/Blue Glasses vs. HD Glasses

4.3 based on 19 ratings

High Definition (HD) glasses allow the wearer to see 2-demensional images in 3D, by the process of selective refraction (bending of light) through the lens changes the perceived depth of different colors. Unlike the traditional 3D process that requires 2 images, HD information is encoded from a single image through the use of binary optics and color,for examplean image composed red and blue when viewed through the HD glassesthe color red appears to move towardthe foreground andoff the face of the paper (or screen) whereas the blue appears to move back behind the paperwith the other colors of the spectrum taking depth positions in corresponding order (red, orange, yellow, green and blue).

Also unlike traditional red/blue 3D glasses the choice of background color is the most important factor in determining the colors which should be used to achieve the 3D effect when wearing HD glasses. The easiest and most commonly utilized background colors are black and dark blue.This is probably why so many underwater scenes and space scenes produce very good 3D images when seen through HD glasses. Bright florescent colors, as well as mixed tones such as brown also produce good 3D effects.

Holograms are photographic images that are three-dimensional and appear to have depth and appear to“pop out” of the media which it is printed on or illuminated from.Holograms work by creating an image composed of two superimposed 2-dimensional pictures of the same object seen from different reference points.

TheChromaDepth®3D process enables HD glasses to take 2 dimensional images and produce holographic 3D which means that the images appear “floating” in a holographic space, that is, parts of the image appears to be hovering above and other parts below. What is actually being seen is a very high quality full color hologram.

Problem

Compare the 3-Dimensional Holographic Effect capabilities of high definition glasses incorporating ChromaDepth® optics to that of the standard Red/Blue color lens 3D glasses.

  • How do high definition glasses allow the wearer to see 2-demensional images in 3D?
  • How dored/blue lens 3D glassesallow the wearer to see 2-demensional images in 3D?
  • What is the difference in the optics between HD andred/blue 3D glasses lenses?
  • Is it possible to clearly see 3Dholographic images wearing standard red/blue 3D glasses?
  • When drawing images what important consideration must be made in order to produce 3Dholographic imageswhen viewed through HD Glasses?
  • Why make geological maps that require the wearing of High Definition glasses instead of standard 3D glasses?

Materials

  • Construction paper, pencil, 48 count crayon box, or bright florescent color marking pens
  • ChromaDepth® HD Glasses
  • Standard Red/Blue color lens 3D glasses
  • Color pictures or images of landmasses, underwater scenes, and/or space scenes

*Safety: Do not look directly at very bright light sources or the Sun while using the HD and 3D Glasses as it may cause permanent eye damage!

Procedure

  1. Select a landform or some other image similar to one shown and draw a rough outline along with its main features on a sheet of construction paper.
  2. Next color in the drawing. Use black and very dark blue as background colors,red forforeground objects, and green for the middle-ground objects.
  3. You can use other colors when you are creating your 3D picture also. Just progress from foreground (red) to middle-ground (green) tobackground (dark blue/black) using the colors in rainbow order.

picture colors

  1. When you've completed your picture, place the image on a flat surface, stand over it, and put on your two different pairs of 3D glasses.
  2. Record the results, using descriptions such as “Fuzzy,” “Lack of color separation,” “Image pops off the paper,” “Image(s) appear to float,” etc.
