Enhancing architectural realism can greatly improve rendered images and in this video tutorial I will share a simple technique that should be applies when modeling 3D designs. The techniques I use can also be applied to any 3D application and for the sake of demonstration I will use Google SketchUp to share the step by step process. In the real world construction materials such as bricks, panels and even windows all have depth, yet often in 3D applications designers use flat 2D planes. Using 2D planes does perhaps allow for faster modelling however for photo-realism we need to use techniques like those demonstrated in this tutorial to simulate physical architecture as we would look in the real world. The basic fundamentals to this guide then is to add detail using edge depth emphasizing the contact of different pieces of material.
Remember that surfaces never fit together perfectly and even spheres are never perfectly spherical in the real world, yet in 3D programs every shape has perfection definition and form. Thus to enhance architectural renders we must take into account the imperfections of physical materials otherwise renders will look to clinical and computer generated.
About the edge depth technique
The idea behind this technique is to define space between materials that meet together at an edge. If for example you place your two hands flat together you will notice that in-between the two hands a small crevice will form, the same applies for architectural materials. Our goal is to create is separation, even if the space is few milometers (mm) in depth and the results will be enhancing realism in your architectural render.
