What types of building information are best portrayed in 3D views?
- Which stakeholders require 2D views, and why?
3D views (Perspective 3D and not isometric or orthographic):
These are the best for understanding relationships between different spaces and objects within interior or exterior spaces. By experiencing the model in a three-dimensional perspective, the viewer sees in a more realistic way when compared to two-dimensional views ( or even orthographic or isometric views). The visual effect of foreshortening creates a sense of curvature and distance. This is not seen in 2D.
2D
While 3D has its advantages, 2D should also be used. Contractors, Engineers, and Permitters often work with 2D sheets. It is easier to measure distances and comprehend annotations.
Give examples of how the building information for a specific location in the project needs to be filtered for different audiences and purposes?
Should your design ideas always be conveyed through photorealistic renders?
- How does the level of detail in the rendering and its presentation affect the perception of stakeholders reviewing your design?
No. Photorealistic images are not always appropriate. They have a high level of detail that can often become distracting when trying to understand simple things. They can generate noise when annotations are overlaid on them. They may not make it easy to highlight specific portions of the design.
Sometimes an image (if made to look theatrical or “epic”) can represent a feeling that is not achievable in reality.
So, it’s a balance with stakeholders. You want them to get excited about a design. You want them to see potential in the design. If the design is shown in an early conversation, then it’s essential not to be too detailed. It will help generate ideas and be a stepping stone for collaborative iterations. If it’s too finished and polished, then a client or team members may not feel comfortable giving input on the design.
Name some applications where viewing the building and model information in virtual reality or augmented reality would be most beneficial?
- Are there advantages to using a C.A.V.E as a virtual environment versus VR headsets?
Help team members and clients experience a space more realistically. You can walk through the environment and discover any issues. If you’re doing a remodel, you might also better understand the different stages of the build.
Headsets compared to CAVE.
The CAVE system fosters a collaborative environment; however, the viewers must stand in similar positions. The projected screens are shown from a single main vantage point as it rotates. In some situations, depth perception may be more natural (if the screens show 1:1). Another advantage of the CAVE system is that no one has to wear a heavy headset.
