3D modeling refers to the process of creating a mathematical representation of a 3-dimensional object or shape. This is done using software. 3D models are now widely used in a variety of industries. Motion pictures, video games, architecture, construction, product development, medical, all these industries use 3D models to visualize, simulate and render graphic designs. 3D modeling in construction is widely gaining popularity due to the plethora of benefits it offers.
Types of 3D modeling
Common types of 3D modeling include simple polygons, 3D primitives – simple shapes based on polygons, such as pyramids, cubes, spheres, cylinders and cones, spline curves and NURBS (b-spline rational non-uniform) – smooth shapes defined by bezel curves. These are relatively complex, computationally.
3D modeling in construction
Technological advancements make every task easier and better. We are now able to do more with less in almost every area of our lives. Every sector is following the technological movement for better results and the construction industry is following suit. Whether it’s BIM or 3D modeling, technology enables the construction industry to do more in less time and at lower cost. 3D modeling is changing the world of presenting architectural designs. 3D modeling allows architects and designers to be more creative and experimental.
With technologies such as reality modeling being inherently integrated into the construction lifecycle, the construction process no longer involves the deployment of building design plans. Construction has largely gone digital. Architectural presentations have moved from draft boards to desktops and tablets.
The adoption of 3D modeling in construction has brought many benefits. 3D or reality modeling not only speeds up the design process, but also allows architects and designers to play with different ideas and identify potential design issues before they become real problems. 3D modeling in construction, putting all the pieces together, provides a real view of the finished project. Surprisingly! 3D modeling brings a project to life without even moving a speck of dust!
3D modeling in construction also enables animation. Naturally, the client can visualize so much more about an upcoming project than a flat drawing could ever provide. Clients can literally have a virtual tour of the proposed building. Just like a 3D movie, a 3D model gives the customer an idea of how things will look. They can walk through the entrance to their future home, reach the hall, and even view guests having dinner in the dining room. They can see it all before a brick is even laid!
With 3D modeling, it also becomes easy to understand a structure in the context of the surrounding space. Transforming a building into a dream home by virtually surrounding it with lush landscaping is the power that 3D modeling offers an architect or designer. 3D architectural modeling offers a degree of realism that 2D images do not have. Thanks to 3D modeling, you can even visualize the texture of the tile that will be placed on the floor of a room. Interesting!
Realistic lighting can be used to demonstrate the warm energy emanating from a kitchen or dining room. It is also possible to fill the space with appropriate furniture and decoration choices to fully understand what we have in store.
There is no doubt that the use of 3D modeling in construction results in better design and better use of materials. 3D models can be rotated for different perspectives and gather additional views. The benefits of 3D modeling include; check for errors that might occur in the drawing process, better understand surface patterns, have virtual tours through walkthroughs, get renderings with custom interiors, get more for less, improve collaboration between teams involved in the construction process.
The essentials for a high quality 3D model under construction
- Pay attention to texture and small details. The customer must be able to imagine what the finished product will look like in the real world.
- Focus on realistic lighting. Without it, the space will appear lifeless and flat.
- Don’t forget to include landscape and background details. Structures floating in the middle of empty space look unrealistic, include trees, bushes and beautiful landscaping to accentuate the digital creation.
Software such as Bentley’s ContextCapture allows users to easily produce high-resolution 3D models of existing conditions for infrastructure projects of all types, from simple photographs. These highly detailed 3D reality meshes can be used to provide accurate real-world context for design, construction, and operation decisions for use throughout the lifecycle of an infrastructure project.
