1 & 2 The new NURBS-based rendering allows users to overcome issues with smaller details in tessellated models But zooming into the details, the tesselation starts to show, particularly on round or highly curved features.įig. That, is the nature of the beast.įigure 2 shows a small detail area in a large model that, at full zoom, looks and renders nicely. While the import options (even as default) do a pretty good job of importing to the right settings, it’s often the case that with large scale, complex assemblies, the global, overall nature of that tessellation means that smaller components might be somewhat faceted. With KeyShot 5, there is now the option to import and, more importantly, use the NURBS data from 3D CAD geometry. To date, KeyShot has relied on the tesellation (conversion of nice clean surfaces into a polygon mesh) to get the data into the system and to base the rendering process on. With KeyShot 5 there’s also been some work done on NURBS-based rendering, which is worth looking at. While this isn’t key for some projects, once you get into using physically accurate light set-ups, it will become more so. There are then tools to assist with repositioning the geometry, scaling it and ensuring that the units match. This will look for part names that match and swap out the geometry, retaining materials as well. Once you have the data loaded into KeyShot, you can kick off another Import session and use the ‘update geometry’ option. While the other options don’t have this capability, it’s worth exploring the tools available to work around this. This establishes a link between the CAD data and the KeyShot session, allowing you to either push local updates, where specific parts have changed, or wholesale updates and have the system retain the material and texture set-up you’ve already worked on. This works with a specific set of data import options (currently, Creo, SolidWorks, Rhino and most recently, Solid Edge and Autodesk Fusion 360) where a plug-in is installed into the host CAD system and data ‘pushed’ to KeyShot. These include the ability to have the geometry centred in the environment, snapping the model to the ground plane, scaling as well as handling mismatches between orientation of different CAD systems’ co-ordinate systems (relating to which axis is considered in the ‘up’ direction).Īlso worth considering is LiveLinking introduced in the KeyShot 4 release. The import process provides a handful of options depending on what you want to do. Non-native or standards-based formats also have a good level of support, including the usual suspects of STEP, IGES, Parasolid and ACIS, as well as STL, Collada, FBX and several more. Both parts and assemblies are supported and you can import more than one set of geometry to build up your scene. These include Alias, Catia, Inventor, Maya, Creo, Pro/Engineer, Solid Edge, SolidWorks, Unigraphics/NX and AutoCAD. The import option allows you to bring in data from a variety of native CAD systems. Importįile import is something that KeyShot has nailed down either through third party data translators or direct integration of CAD vendor’s libraries. These follow the workflow required to set-up a model, so let’s follow them. The majority is devoted to the model viewing area.Īs experienced users will know, there’s a strip of icons along the bottom of the screen that bring up various panels or task specific dialogs. The user interface is clean, which is a rarity in standalone rendering systems. With that in mind, let’s step through how the system works (for the benefit of those that haven’t used the system) then look at what’s been added, changed and enhanced.Īs a lot of work has been done on how the user interface is laid out, let’s look at KeyShot from first principles. With KeyShot 5, the team behind the product has stepped back and given the user interface a refresh, added in a bunch of new tools to advance the state of the art - as you’d expect from a major release. It’s clean, it’s lean and it has found its way into many users’ toolkits. Developed by Luxion, it’s a progressive renderer, meaning you get the visuals streamed to your screen, rather than waiting for a full test render to finish. One of the leading exponents of the standalone crowd is KeyShot. Fig.1 KeyShot 5 sees an overhaul of the user interface to bring commonly used commands to the fore and open up the system’s various options and commands (HDRI environment and back-plate from )
