Visualization is best understood as a process where what you see is what you get. It can be categorized into four main types based on professional fields:
1. Scientific Computing Visualization: This involves using graphics to transform large datasets generated through scientific and engineering computations into intuitive, visual representations such as images and charts.
2. Data Visualization Technology: This refers to the methods and technologies used to convert various types of data into iconographic images displayed on screens, enabling effective human-computer interaction.
3. Information Visualization: This connects computers and the human brain by converting data into visual forms that leverage our brain’s ability to quickly recognize visual patterns, helping us understand relationships and trends behind the data.
4. Knowledge Visualization: This encompasses all graphical techniques used to construct and communicate complex knowledge. Beyond conveying factual information, it also shares insights, experiences, attitudes, values, expectations, opinions, and predictions.
In essence, visualization is characterized by its intuitive nature, and its strength lies in organizing and aggregating complex information. This enhances users’ ability to analyze data, uncover hidden patterns, and identify developmental trends. Broadly speaking, in engineering, tools such as CAD 2D drawings, photographs, computer renderings, animations, and BIM models all fall under the umbrella of visualization.
BIM, in particular, stands out as a highly visual and advanced application of visualization technology within engineering. Thanks to rapid advancements in computer technology and the growing adoption of BIM in the construction industry, visualization has reached new heights and is widely applied across engineering projects. A comprehensive visual information model integrates all data, processes, and resources across different phases of a construction project’s lifecycle. This model offers a detailed representation of the engineering object and can be utilized by all stakeholders involved.
After thorough analysis, BIM visualization models exhibit the following key characteristics:
1. Integrity: BIM visualization models include not only 3D geometric data of engineering objects but also comprehensive engineering information tailored to project needs. This covers object names, structural types, materials, component properties, design details, construction schedules, costs, quality metrics, and resource management such as labor, machinery, and materials. Additionally, they incorporate maintenance data related to safety and durability, as well as logical relationships between engineering elements.
2. Relevance: BIM models establish interconnected information systems where different objects can be transformed, identified, and associated within BIM software suites. Any modification to one object automatically updates all related elements to preserve the model’s integrity. Furthermore, the system can perform statistical analyses on the model’s data and generate summary reports.
3. Consistency: Throughout the building lifecycle, the BIM model evolves automatically. Objects within the model can be easily updated or expanded according to real-world changes at various project stages without needing to be recreated from scratch. This reduces errors caused by inconsistent information and ensures data coherence.
These attributes enable BIM visualization technology to revolutionize traditional workflows. By integrating data models, BIM enhances interactivity and collaboration, fosters information sharing during project execution, and supports every phase of the construction process. As a result, it effectively meets the demands of comprehensive information management throughout the entire building lifecycle in the modern era.
