Rectified vs Non-Rectified Tiles for 3D Rendering

What is the difference between Rectified and Non-Rectified tiles?

Usually a client will specify if they are using Rectified or Non-Rectified tiles in their finish schedules. Simply put, rectified tiles have a straight cut edge and have been 'rectified' to all be identical. Non-rectified tiles have a more natural edge, weather it be uneven or smoother. Here is a bit more detail on each.

Non-Rectified Tiles - These were the industry standard many years ago, and were a bit more forgiving with the installation process, needing suiting wider grout joins and not needing to be exactly laid to look straight and even.

Rectified Tiles - These are more and more common these days giving a more modern and aesthetically pleasing feel, allowing for a smaller or almost no grout joins. By their nature they are more difficult to install and require exact precision to get looking straight and even.

So how does this effect you when your trying to create an artist impression of a space?

A designer, builder or developer will go to great lengths to ensure their project has the look and feel they are after, that will sell to potential buyers. This also is factored into budgets and and timelines for construction and contractors. If they are after a certain look with their bathrooms, for example a modern and sleek design with something that appeals to a younger more wealthy buyer, they might specify a range of rectified tiles (above and left) and factor in the costs of a high end professional tiler to install them to get they look and quality finish they are after. They would also have to specify certain grout sizes and corner joins for installation processes, but that is for a future post.

As a 3D artist, being able to understand and visualize these two different types of tiles allows your client to see and feel the end result of their hard work and as a visualizer you show that you understand that these things are important to the clients design and selling process. This not only gives your images a more realistic feel, it allows you to show the end result more accurately and true to the design.

Our Process when creating tiles

This tile creation process gives you some flexibility to create different edges sizes and grout amounts. We use Floor Generator, which you can download here from CGSource.

Step 1 - Create a flat polygon or enclosed line shape and add the Floor Generator modifier.

Step 2 - Once you are happy with your overall tile size and proportions, add an Edit Poly modifier and go into polygon selection mode (you will notice all of the top faces will be selected by default)

Step 3 - CTRL click the Edge selection mode button to select all the edges touching the polygons that were selected. Then press Grow once and Loop once to select all the edges on the sides of the tiles (this wont select the bottom edges)

Step 4 - Add a Chamfer modifier to the stack, and chamfer those selected edges. A large chamfer (3-5mm) for Non-rectified tiles and a small chamfer (0.5-1mm) for rectified tiles.

That is all there is to it. Soon we will put up a video showing the exact steps how to do this, so keep an eye out for that coming soon.
