The descent behavior to two- and three-dimensional surfaces in a depth situation was measured and compared for 45–50-days-old hooded rats. When depth differences between surfaces were controlled, significantly more descents were made to three-dimensional than to the two-dimensional surface. The results suggest that a three-dimensional surface—more representative of an animal's natural terrain—provides a more informative environment for motion parallax than does a two-dimensional one.

The perspective transformations of the retinal image, produced by either the movement of an observer or the movement of objects in the visual world, were found to produce a reliable, consistent, and unambiguous impression of relative depth in the absence of all other cues to depth and distance. The stimulus displays consisted of computer-generated random-dot patterns that could be transformed by each movement of the observer or the display oscilloscope to simulate the relative movement information produced by a three-dimensional surface. Using a stereoscopic matching task, the second experiment showed that the perceived depth from parallax transformations is in close agreement with the degree of relative image displacement, as well as producing a compelling impression of three-dimensionality not unlike that found with random-dot stereograms.

It is shown that, in the three-dimensional lattice gravity defined by Ponzano and Regge, the space of physical states is isomorphic to the space of gauge-invariant functions on the moduli space of flat SU(2) connections over a two-dimensional surface, which gives physical states in the ISO(3) Chern–Simons gauge theory. To prove this, we employ the q-analogue of this model defined by Turaev and Viro as a regularization to sum over states. A recent work by Turaev suggests that the q-analogue model itself may be related to an Euclidean gravity with a cosmological constant proportional to 1/k2, where q=e2πi/(k+2).

this thesis puts forward the idea of using the searching method to retrieve two kinds of data points of the circle and the square to generate DEM data of the collected discrete points by means of using C# language and OpenGL DLL, thus realizing the visualization of the three-dimensional virtual terrain from contours on the two-dimensional surface. This thesis makes a comparison and analysis of the visualization effect which indicates that this algorithm is quick and effective. This research has a certain reference value for the formation of the virtual battlefield terrain.

Response Set

Geometric considerations of the two-dimensional projection of the three-dimensional visual field led to hypotheses about the possible effect on depth perception of: relative height in the picture plane, the type of supplied reference plane, and angle of regard. In three experiments Ss viewed pairs of equidistant, horizontal rods in front of one of four backgrounds, with either an upward or downward angle of regard. The results confirm the hypothesis that relative height can operate to influence depth perception, that the type of background influences depth perception in the predicted direction, and that a response set resulting in a tendency for Ss to see higher objects as farther irrespective of the reference plane also occurs. The effects of angle of regard and of degree of vertical separation were not completely elucidated.
