Real image. When a number of rays starting from a point after reflection or refraction actually meet at another point, that point is called real image of the first point. A real image can be obtained on the screen. Virtual image. When a number of rays

In addition, the virtual database can never include dynamic objects, such as a car parked on the street, road construction, etc. Fig. 1 shows such an example: Fig. 1(a) is a database image and Fig. 1(b) is a video image that has the same scene as in (a). As one can see,...
Hi, Im new in c# , I have an image in picturebox and draw a line connecting within two coordinates points x1, y1 and x2, y2. I wonder if there is any way of calculating the size of the line in centimeters. If i can have an example i will thank. Thanks .. ed All replies (...
The figure below shows an object and its image formed by the lens. Is the image real or virtual? Light Rays: Light rays are arrow representations of the directions where light propagates. Normally, light rays are drawn in relation to the interaction of light...
The effect of applying this transformation to the texture coordinates is that a convex region of the surface will magnify the image behind it, a concave region will shrink the image, and flat (with respect to the viewer) regions will allow rays to pass straight through...
Representational fidelity refers to the quality of the display to provide high realism, the smooth display of view changes and object motion, the consistency of object behaviour, the quality of the user representation within the 3D virtual learning environments (VLEs), the spa- tial audio, the ...
