This was been followed to achieve that were: done by generating multilayer drawing ,which within 1-Drawing the plan horizontal projection of the alley each layer ,a particular component or attribute was.
This was obtained from Mosul municipality maps, constructed according to its rhythmic properties as Mosul map drawn by Ernst Herzfeld in fig.
The difficulties may arise in vacant areas where demolishing works were done without any new erections. In this case ,records from municipality are very helpful in determining the height of the demolished unit.
Layer2: This is the layer of main openings in the lower ground level. These openings are characterized as a highly functional ones since they are used as main entrances for the buildings.
The rhythm here is of alternating nature besides that the borders between units surrounding the alley are very helpful since in most cases each unit has only a single opening entrance.
Layer3:This is the layer of openings in the lower ground level also but with less function as in the previous layer. This may include windows in ground level which are characterized by their limited dimensions and achieve very little participation as a Figure 3:Mosul map in by E.
The rhythm here is simple presentation including colors and textures of and obvious and the openings are rarely be in materials.
Layer4: This is the layer of function-less openings and other elements in the lower ground level and few ones in the upper level. Elements such as niches , friezes, dado and other moldings may included here.
In this layer , the rhythm is vague and ambiguous to some extent.
This is because the rhythm is implicit within some complicated manner , however , these openings are little and very rare. The friezes , which are the most dominant feature in this layer are located , in most cases, with floor traces in the outer wall , which is 3.
Layer5: This is the layer of openings both functional and non-functional in the upper level. The manner of rhythm here is similar to that in layer 3which is also simple and obvious.
Layer6: This is the final layer. Here all elements are elaborated with details driven from domestic architectural elements and patterns.

Ornament is also added in proper locations as it appears in local examples. It is possible to observe that there is a reasonable amount of similarity between the real photo and the constructed one. Some differences can be seen especially in details like openings lintels, dados and some ornaments.
These are produced because there is a lot of types of such details that could be selected Figure 6:Layers of attributes and components in and no one could be determined as the exact one. Certainly, this is Modeling workspace, which gives us a set of tools to not an alternative to real and accurate documentation help ease our way into 3D modeling.
We can treat both solid and surface objects as if they were 4. Other locational elements reasonable similarity which is obtained from the such as slope of the alley were added to give more derivation of shape grammar approach based on the reality to the scene, a number of shots could be make analytical study of the facades properties with with various stationary points as shown in figure 7.

Comparative methods are very familiar in classified groups of elements and details of the archaeological studies where different materials are domestic architecture will be very important in categorized according to some spatial or temporal achieving the reconstruction Figure Real photos and rendered images of selected parts of the alley's facades authors City Street: Cultural Intimacy and Global Image.
New York , Today, 3D models are used in a wide variety of fields. The medical industry uses detailed models of organs; these may be created with multiple 2-D image slices from an MRI or CT scan.
The movie industry uses them as characters and objects for animated and real-life motion pictures. The video game industry uses them as assets for computer and video games.
The science sector uses them as highly detailed models of chemical compounds. The engineering community uses them as designs of new devices, vehicles and structures as well as a host of other uses. In recent decades the earth science community has started to construct 3D geological models as a standard practice.
Solid and shell modeling can create functionally identical objects. Differences between them are mostly variations in the way they are created and edited and conventions of use in various fields and differences in types of approximations between the model and reality.
Shell models must be manifold having no holes or cracks in the shell to be meaningful as a real object. Polygonal meshes and to a lesser extent subdivision surfaces are by far the most common representation. Level sets are a useful representation for deforming surfaces which undergo many topological changes such as fluids.
The process of transforming representations of objects, such as the middle point coordinate of a sphere and a point on its circumference into a polygon representation of a sphere, is called tessellation. This step is used in polygon-based rendering, where objects are broken down from abstract representations " primitives " such as spheres, cones etc.
Meshes of triangles instead of e.
The modeling stage consists of shaping individual objects that are later used in the scene. There are a number of modeling techniques, including:. Modeling can be performed by means of a dedicated program e. In some cases, there is no strict distinction between these phases; in such cases modeling is just part of the scene creation process this is the case, for example, with Caligari trueSpace and Realsoft 3D.
Photogrammetry creates models using algorithms to interpret the shape and texture of real-world objects and environments based on photographs taken from many angles of the subject.
Complex materials such as blowing sand, clouds, and liquid sprays are modeled with particle systems , and are a mass of 3D coordinates which have either points , polygons , texture splats , or sprites assigned to them. The first widely available commercial application of human virtual models appeared in on the Lands' End web site. The human virtual models were created by the company My Virtual Mode Inc.
The development of cloth simulation software such as Marvelous Designer, CLO3D and Optitex, has enabled artists and fashion designers to model dynamic 3D clothing on the computer. Some graphic art software includes filters that can be applied to 2D vector graphics or 2D raster graphics on transparent layers.
Disadvantages compare to 2D photorealistic rendering may include a software learning curve and difficulty achieving certain photorealistic effects. Some photorealistic effects may be achieved with special rendering filters included in the 3D modeling software. For the best of both worlds, some artists use a combination of 3D modeling followed by editing the 2D computer-rendered images from the 3D model.
A large market for 3D models as well as 3D-related content, such as textures, scripts, etc. Often, the artists' goal is to get additional value out of assets they have previously created for projects. By doing so, artists can earn more money out of their old content, and companies can save money by downloading pre-made models instead of paying an employee to create one from scratch. In most cases, the artist retains ownership of the 3d model; the customer only downloads the right to use and present the model.
Some artists sell their products directly in its own stores offering their products at a lower price by not using intermediaries. Over the last several years numerous marketplaces specialized in 3D printing models have emerged.

Main articles: Or it may take the more interesting and units which can be related to create buildings. Often, the artists' goal is to get additional value out of assets they have previously created for projects.
A wide number of 3D software are also used in constructing digital representation of mechanical models or parts before they are actually manufactured. For scientific usage, see Computer simulation. This book is written as a tutorial, so many details are left out and assumptions made in order to generalize some of the more difficult concepts.
