Christchurch Cathedral Rebuilds Using 3D Rendering and Traditional Craft

In 2011, a devastating earthquake destroyed Christchurch Cathedral. Now, digital collaboration and traditional craft are working together to rebuild it as the city’s spiritual heart and civic nexus.

Specialists in 3D rendering Christchurch are able to take digital designs and build a model of the project. This is helpful for architects, engineers, and contractors to understand what the finished product will look like.

Christ Church Cathedral

Christ Church Cathedral is the heart of Christchurch, a historic place of heritage and religious significance. It was severely damaged in the 2011 earthquake and needs to be strengthened, reinforced, and reinstated as the city’s civic and spiritual nexus. To do that, architects and engineers are using digital collaboration to rebuild this iconic structure.

Warren and Mahoney, a Pacific Rim architecture firm, has created a single digital model for the cathedral’s entire structure, pulling together a variety of sources, including original architects’ drawings, early photographs, a full catalog of every stone fragment that fell off the cathedral, and point-cloud scans. The result is a more accurate model that allows the project team to work more efficiently.

The cathedral’s west rose window, for example, depicts the Last Judgment, a traditional theme for this type of facade. The 3D model helps the team visualize how each element of this ornate stained glass will fit together. This process is known as building information modeling (BIM). Architects, engineers, and contractors can use it to improve coordination and communication between design teams.

3D rendering is a great tool for helping clients visualise construction projects. A specialist in 3D architectural rendering can take all of the building plans and design information and create a digital model of the construction project. This model can be viewed using a virtual reality headset and can provide more information to the client than a standard photo. These experts can also assist with 3D scanning of buildings and structures and collect valuable data on the topography of the property where construction will occur.

The 3d render for Lujo New Zealand allowed the brand to see their products in a variety of different fabrics which they can’t produce with traditional studio photography. This process also saved time and money by producing consistent results which would be impossible to achieve with a high number of individual product studio shoots.

The use of high polygon geometry and physically correct materials in this render allows the designer to show a wide range of different styles within the same scene. This is a huge advantage over the traditional photography process which requires a large amount of set up and a lot of time to produce each iteration of a product.


When US-based Sealegs wanted to add an amphibious boat to their range they asked NZ boat builder ReconCraft and engineering specialists Blender to design a new 8.5m boat that could work with their larger Amphibious Enablement System. Working in conjunction with hydraulic engineers and naval architects Blender helped develop the visual impact design of the new boat, which has become known as the ‘IKA11’.

Paint colours have a unique way of absorbing properties from the objects and buildings around them. Colours can take on the undertones of red brick walls, vibrant gardens and artwork, or even the colour of furniture and other items within the room. A good 3D rendering Christchurch professional will understand how to match these undertones with the correct paint colours.


Lujo New Zealand a premium hammock brand needed 3d renders of their new Tropicalia fabric sourced from James Dunlop Textiles to replace older photo manipulations. This was a very complex illustration that required a high polygon geometry to simulate fabric folds and shapes along with ray trace materials to produce a realistic result. This was achieved using a program designed specifically for garment simulation CLO3D, then exported to another software more suited for rendering and material application.

Sealegs wanted a way to show their customers what their one off design craft would look like before construction. This was achieved by using 3d rendering to place the high polygon geometry of their product into a landscape scene. This was done with physically correct lighting to allow both parties to clearly see the finished product before negotiating a sale.

The use of a virtual camera in the modelling software allows for adjustments of composition and field of view without needing to tilt the real-world camera which would induce skewed vertical lines. This was particularly important for this image that was to be printed on billboards.
