FUNCTION

Code 4: Administrator(s) room

Code 5: Staff rooms: with less degree of interaction comparing with nurse and caregivers, staffs and their spaces are classified in the fourth degree. In addition, all of the private access or corridors with limited access for staff or limited persons have got this code.

Code 6: services: all activities with aim of providing services for other sectors and the utility rooms. Storages and store rooms for sanitary equipment’s are classified in this sector.

Qualificative analysis and Virtual Reality

While space syntax methods are applied to analysis of space distribution in the building, there are some shortage and failure in the theoretical and practical methods that are involved in the terminology. Using BIM might accelerate the process and could attach all maps needed to approach the result but following failure due to basis of present approaches are still taken into consideration:

1. All information of distribution of spaces that are driven from floors plan are two dimensions, while space could be defined by at least three dimension.

What is introduced to space as spatial information, is not enough to perceive the characteristic of space and relationship existing between them. The third dimension will elevate the given information in documents. The height of a room affects the way that this room is understood by users and the way that they will access to the function. A vast room (in terms of height) with large door to access is much more inviting comparing to a short ceiling room with a short and limited door the same plan design. This three dimensional information cannot be easily mapped and documented.

2. Only quantities information is not playing role in the analysis. the spatial qualities are important to introduce a space and spatial characteristic.

Namely color of walls, furniture and equipment, the artificial and natural light in the building. Mentioned feature are involved to access to a room in a indirect way. A dark room without enough opening to obtain the natural light and with dark or sharp color is perceived as an inaccessible and deep even with the same access code and the same quantitative information.

3. Fourth dimension: time

All theories of space syntax are arguing about the possibility of movement and access from space to space it is impossible to have a comprehensive view toward the argument without having possibility to move in the building or urban zones.

By passing as a pedestrian it become possible to analyses the sequence of spaces. With this possibility human is perceiving the built environment and he judge them and regarding that he is going to name the different qualities of space with the specific terminology. For instance, Welcoming space or receptive zone…

The best quality traditional render of 3D modelling done by architectural software are providing the enormous information about architecture but are unable to make users able to understand the sequence and flow of space.

Introduction to Virtual reality From Revit to Unity

After creating the model of the building with attached information as defined regarding with the aim of the project. It is needed to export and represent the provided data and graphical document. In this stage as Revit offers we could have the Excel files outputted from the schedule with all information created into it. At the same time, it possible to have graphical export from the unique scene as it is wished. Also, in a specific environment in the Revit, dynamic vision considering the time is provided.

But as it is mentioned before in the aim of the thesis, better quality render with the more dynamic option is made by a software in VR and AR environment called Unity. In this thesis after crating model with all attached information the process of presentation will continue to have a dynamic on-time render in the Unity Software.

In this stage one of the main shortages of the procedure occurs as it is impossible to convert the Revit model with All of the information about materials and families into the Unity.

The solution is obtained by using a bridge software as 3D Studio Max. in this transforming the meaning of FBX is used. As they are files in between a lot of modeling tools. A FBX file is a file with formal data of a three dimensional model to make users possible to transfer between them.

Figure N: a Mediator software will be needed to keep the detail of model

The mentioned stages are presented to convert the Revit model into the Unity Environment with all details and information:

1- Exporting a BIM model from the source environment as a FBX file with .fbx suffix. It should be mentioned that LOD level must be justified as Medium.

2- Import the FBX file in the 3D Studio Max with the modified Preset and Bind the imported model

3- Applying Converter Scene and using Standard Material to Physical Material.

4- Re-Export the file in to FBX file another time 5- Import the defined file into Unity as a new asset.

Addressing the issue

One of the most important issues involving in this method is that there is no direct way to import the BIM model into Unity as a complete asset with all materials attached to the objects.
