Three Dimensional Images
Digital illustration programs can produce wonderful 3-D images of insects that seem to come alive before your eyes. Intricate detail is revealed as the insect displays its secrets.
To see three dimensional images, you need to wear a pair of special glasses that allows your eyes to view an image from slightly different angles. Two images are taken of the object, one as though from the left eye and one from the right eye. The two images are superimposed on each other in slightly different positions. The glasses have one red lens and one coloured cyan-blue, a combination that tricks our brain into thinking that it is really looking at a 3-D image.
You can make your own glasses with the following instructions.
What you need
- Red cellophane
- Blue cellophane
- Cardboard for making glasses frames
- Scissors
- Glue or sticky tape
- Red and blue coloured pencils or felt pens
What to do
Design frames for the glasses and cut them out of the cardboard
Glue or tape red cellophane over one eye of the glasses and blue cellophane over the other eye.
