A computer graphics facility was then used with available crystal data, molecular orbital and molecular mechanics calculations/ infra-red and n.m.r. studies to construct a three dimensional model of the target enzyme active site (a cytochrome P-450) designed specifically to accommodate both the natural substrate (24 methylene 24 25 dihydrolanosterol) and these known antagonists in their minimum or low energy forms. 

Because we can measure—or reliably estimate—all three of these brain functions, we can construct a three-dimensional model representing (1) the energy level of the brain and its component parts (Factor A, for Activation) (2) the input-output gating status of the brain, including its internal signaling systems (Factor I, for Information Source) and (3) the modulatory status of the brain, which is determined by those chemical systems that determine the mode of processing to which the information is subjected (Factor M, for Modulation).

For a triatomic molecule U will be a function of three internuclear distances, and a potential-energy diagram analogous to Fig. X.2 for a diatomic molecule would have to be constructed in four dimensions. For such a case we can construct a three-dimensional model in which we can... 

The sea floor is represented by model cells, where the normal horizontal and vertical flux from the bottom into the cells is set to zero. This requiies a data set with information on the Baltic Sea bathymetry. In the late 1980s, at the outset of three-dimensional modeling of the Baltic Sea, gridded topographic data with sufficient accuracy and resolution were constructed from nautical maps, data from research cruises, and other data sources. One of the most complete data sets, used today for many Baltic Sea model projects as a standard, was compiled and regularly updated by Seifert et al. (2001), see Section 20.2.5.

The work of the construction of three-dimensional scene is mainly to make each individual object integrated in the model of Unity3D (integration of terrain) while adding relevant environmental, physical and other elements to form a complete three-dimensional virtual reality simulation scenario. With the management function of Unity3D model, we integrate and build three-dimensional simulation scene with the object model and environmental factors... 

The construction of three-dimensional atmospheric trajectories provides a valuable diagnostic tool for illustrating and smdying three-dimensional flow fields and associated transports. The trajectories are calculated from simulated wind fields, with both horizontal and vertical wind components derived from the Eta model. Trajectories can be calculated forwards and backwards in time. Air back trajectories are calculated by specifying the final location of air parcels and time, and then tracing the air parcels with decreasing time to ascertain their origins. The time steps for the forward and backward trajectories were 1.5 min and 60 min, respectively. 

Construct a three-dimensional model or drawing of the transition state with the relevant AOs (e.g.. Figs. 5.35-5.37). 

In Fig. 17.11, the process of reconstruction is summarized. In the first step, the radiographs, which are obtained in the way as it is described above, are combined digitally. This combination allows the creation of two-dimensional volume slices. These slices will be assembled to construct the three-dimensional model of the scanned sample [80, 82],...
