Christchurch Cathedral Rebuilds With 3D Rendering

Christchurch’s cathedral was severely damaged in the 2011 earthquake and is currently being rebuilt through digital collaboration. The Christ Church Cathedral Reinstatement project is a great example of how traditional craftsmanship and new technologies can coexist.

High polygon geometry and physically correct materials allow for a realistic result with consistent lighting that is hard to achieve in studio photography. The resulting image can also be manipulated to show multiple colour ways without the cost of studio photography.

Building Information Modelling (BIM)

Building Information Modelling, or BIM, is a new method of designing and constructing buildings that replaces traditional paper drawings with digital three-dimensional models. The models can be used to simulate different construction scenarios and identify potential problems before they become a real problem during the actual build. This technology is already being used on some of the world’s largest construction projects.

The BIM process allows all parties involved in the design and construction of a project to collaborate and share data throughout the lifecycle of the facility. It incorporates several processes and systems into a single model, including design, planning, and construction. It also supports a number of other activities, such as facility management and maintenance, operation, and asset management.

BIM software has built-in cost estimating features that can help with calculating material quantities. This can save time, money, and energy during the construction process. Additionally, it can aid in preparing fabrication/shop drawings, which are needed for the proper installation of building components. For example, a 3D model can be used to create shop drawings for sheet metal ductwork and electrical conduit.

Specialists in 3D rendering Christchurch can use BIM to assist clients in visualising the end result of their building project. This is especially important for clients who are unable to picture what their building will look like once it is completed. These professionals can also gather valuable data on existing structures and topography on the site of the construction.


Using 3D rendering services is a cost-effective way for real estate companies to show potential clients the details of their properties without having to hire photographers and arrange time and locations. This saves on overhead and allows real estate agents to focus on other business matters at the same time.

Rendering in the real-time environment requires fast calculations to produce images at 24 frames (frames) per second, to avoid tearing and respond to user input with acceptable latency. This is achieved by separating 3D object geometry into smaller units called vertices, which are used to describe the position and orientation of a surface or point in space with respect to other surfaces.

To achieve a high-quality image, 3D rendering software uses complex algorithms to calculate the light interaction with the model and apply realistic lighting and shadows. These programs also include advanced ray tracing to accurately simulate light behavior in the real world. This technology produces images with supreme realism and offers the ability to add multiple lighting sources, which allows users to create a variety of visual effects.

A 3D architectural render is an excellent tool to communicate design ideas and concepts to non-experts and architects. It helps them understand the final product, including how different materials look in a room and how the design will work with natural light. These images can also be used in presentations or online.


Realism is what makes 3D renderings look like photos, and it requires meticulous attention to detail. The smallest details can make or break the quality of the final image. This includes everything from the lighting setup to texture mapping, and making sure that all the objects in the render are sized correctly and match their real world counterparts.

It’s also important to note that no surface is ever completely perfect in the real world, so it’s important to add some of that to a 3D rendering as well. It’s a great way to add some extra authenticity to a scene and help the viewer feel like they are looking at a photo.

Adding the right atmosphere to a 3D render is another important aspect of realism. This can be achieved using lighting, textures, composition, and post-processing techniques. For example, adding rough and weathered textures to a render can give it an aged or vintage feel, while glossy materials can create a futuristic or sleek look.

Finally, one of the most common mistakes when creating a photorealistic 3D rendering is not paying attention to lighting. This can lead to a lack of depth and realism, so it’s important to pay close attention to the lighting in your scenes. It’s also a good idea to avoid overusing post-production effects, as they can sometimes detract from the quality of the final image.


3D rendering artists collaborate with engineers and architects in a real-time, networked environment. This collaborative virtual design environment combines the physical digital technologies of scanning and rapid prototyping specific to the VUW Industrial Design program with the ‘virtual’ technologies of a 3D immersive theatre developed at HitLab NZ. The collaboration system utilises open source desktop 3D modelling software (BLENDER) to link to the immersive server and enable simultaneous real time sharing of design concepts in an immersive 3D theatre.

Using high polygon geometry with physically correct materials allows for consistent product visualisation. Stainless steel for example can be rendered as flawless material rather than showcasing machining defects which is difficult to achieve in traditional photography. This is especially important for small products as it helps to communicate the quality of your brand and avoid any misunderstandings about a product.

The ability to create a single render with separate colour designs for each product saves significant production costs. It also allows you to produce a wide range of variations on a theme which would be cost prohibitive for studio photography. For example, Lujo New Zealand a luxury hammock brand required 3d renders for each of their hammock products with different James Dunlop textile fabric patterns. This saved on producing multiple studio photographs of each product in each fabric colour way.
