![]() ![]() When all is said and done, the trick when optimizing a 3D model is to reduce polygon count without impacting the overall look and accuracy of the model. Here is an example of how polygons are used in 3D objects, and how they can vary widely:Ībove: The same object with three different polygon counts. If these trees are just background items, then you may be creating a very heavy scene in Lumion, unnecessarily. For instance, one tree can include 2,000 polygons while another, similar-looking tree can contain over 20,000 polygons (if it is inefficiently built). Furthermore, inefficient 3D object building can lead to huge polygon counts for a little improvement in detail. Typically, 3D objects with a higher polygon count will look better (extrusions, beveled edges, chamfer edges, etc), but these high-detail models will demand more performance from your computer. Polygons in a detailed rock model (SketchUp). These are triangular surfaces with three points (also known as vertices or 3D points), and in every 3D object, these polygons contain certain information associated with it, such as the texture, light and shadow mapping, and more. What are polygons in 3D objects?Īll 3D objects, also known as 3D models, are built up of polygons. Please note that this article focuses on SketchUp, Revit and ArchiCAD models, though some of the tips you’ll learn here can apply to your modeling software. In this blog post, we’ll take you through a crash course on 3D model optimization and how you can reduce the size of your 3D models for faster performance in Lumion. It’s pretty easy to spot the difference in quality. Low-polygon model on the left, high-polygon model on the right. One possibility is to optimize your 3D model by implementing efficient modeling techniques or reducing the model’s polygon count, all without negatively impacting the visual quality of your model. When exporting your model from your 3D modeling software, such as SketchUp (above left), reducing its complexity may improve performance in Lumion. So, what can you do to reduce the model size and improve your Lumion experience? These details have made the model quite heavy and, while Lumion is certainly capable of handling large models with ease, sometimes the model can become so huge that it ends up slowing down the performance in Lumion’s real-time editor. The model includes complex, intricate details such as beautiful, carefully selected nature objects and highly realistic materials and textures. Imagine you created an incredibly detailed 3D model of your latest design. Want to speed up your Lumion performance? Follow these helpful, 3D model optimization tips to reduce the size of your models and improve your real-time rendering experience in Lumion.
