## What are the fundamentals of stereoscopy?

Stereoscopy is a physiological and geometric process. To get a stereoscopic sensation, the image in our left eye and the image in our right eye must be similar, but with slight geometric differences. In this case, our brain will interpret the scene for stereoscopic effect.

**What is the purpose of stereographic projection?**

Stereographic projection is a technique for displaying the angular properties of a plane faced object on a single drawing or diagram. Directions as well as planes may be shown and any desired angle can be measured directly from the projection using a graphical technique.

**What is meant by stereographic projection?**

Definition of stereographic projection : a map projection of a hemisphere showing the earth’s lines of latitude and longitude projected onto a tangent plane by radials from a point on the surface of the sphere opposite to the point of tangency.

### Why do I see magic eye inverted?

MOST MAGIC EYE IMAGES are built to be viewed by allowing your eyes to diverge, as if you’re focused on an object more distant than the printed page. If you cross your eyes you’ll also see in 3D, but you will invert the image (see the image inside out).

**What is Orthomorphic projection in geography?**

A projection in which the scale, although varying throughout the map, is the same in all directions at any point, so that very small areas are represented by correct shape and bearings are correct.

**What is the difference between the E-10 and E-20?**

The E-20 is a progression from last years 4 megapixel E-10. The E-20 has all the same basic functionality, control layout, body design and lens. The lens remains the same as the E-20’s 5 megapixel sensor is the same size as the 4 megapixel of last year.

#### What is stereographic projection in geometry?

In geometry, the stereographic projection is a particular mapping (function) that projects a sphere onto a plane. The projection is defined on the entire sphere, except at one point: the projection point. Where it is defined, the mapping is smooth and bijective.

**How many megapixels is the sensor on the E-20?**

The lens remains the same as the E-20’s 5 megapixel sensor is the same size as the 4 megapixel of last year.

**What is the stereographic projection of plane inversion?**

These spirals intersect radial lines in the plane at equal angles, just as the loxodromes intersect meridians on the sphere at equal angles. The stereographic projection relates to the plane inversion in a simple way. Let P and Q be two points on the sphere with projections P′ and Q′ on the plane.
