You can watch the full presentation at OGS-Autodesk (registration required). The presentation then went on to show the path tracing mode of the new engine working inside in Autodesk 3ds Max, Maya and Inventor. This resulted in some ‘noise’ when moving the camera, but the image resolved very quickly when idle by casting more rays and using denoising. In order to achieve a smooth viewport experience, the frame budget was set to 30 frames per second. Vives showed off the render quality by highlighting several aspects within the scene, including contact hardening soft shadows, real ambient occlusion and glossy reflections, focusing in on the subtle reflection of a black socket on a red paint finish. The scene was lit by a single directional light and a low frequency environment light. Render quality was photorealistic and looked impressive, much better than the rasterisation engine currently used in Inventor 2022. In a demonstration of a path traced reference application, Vives showed a welding robot model that originated in Inventor.

Inventor – Lights, camera, action Autodesk’s new One Graphics System (OGS) will be able to take advantage of new generation GPUs like the AMD Radeon Pro W6600 which include hardware-based ray tracing In Inventor, for example, we imagine it will be just another visual style to add to the current drop-down for wireframe, shaded, realistic, monochrome, watercolour and sketch / technical illustration. “They just need a very simple solution with literally no settings,” he says. “Photorealism is important, but we prioritise performance over quality,” he says.Īccording to Edstrom, it will be very easy to use for non-rendering experts.
Inventor currently relies on CPU rendering which takes a long time and the results can be mixed.įor the new engine, Vives explains that the emphasis is to provide a good real time experience, like you get with a game engine. The idea is that when working on a model in the viewport, a product designer or engineer can quickly switch to full ray traced quality at the click of a button. Rather than looking at performance in simple shaded views, the focus was on the eye-catching stuff - real-time ray tracing.

Inventor – Nvidia GTC showtimeĪutodesk’s Henrik Edstrom, senior software architect, graphics technology, and Mauricio Vives, senior principal engineer, gave a sneak peek of the ‘next-generation’ viewport system in a presentation at Nvidia’s GTC conference earlier this year. It will utilise open standards, such as MaterialX and Pixar’s Hydra, part of USD. The modernised OGS will also be able to use hardware-based ray tracing, which is built into modern graphics cards such as the new ‘Ampere’ Nvidia RTX A2000, A4000, A5000 or A6000, or ‘RDNA 2’ AMD Radeon Pro W6600 or W6800. As a result, 3D performance in the software is largely bottlenecked by the frequency of the CPU.Īutodesk’s ‘next generation’ viewport system should fix this, and users should get a much smoother viewport experience without having to rely on the software to temporarily simplify or discard parts of the view during model navigation by setting a minimum frame rate.īy fully utilising modern graphics APIs including DirectX 12 and Vulkan, Autodesk’s applications will be able to talk straight to the GPU hardware (rather than having to route everything through the graphics driver) and take better advantage of multi-core CPUs. Inventor, like many other CAD applications that use older graphics APIs, isn’t the best at harnessing the plentiful power of modern Graphics Processing Units (GPUs). It dates back to 2007 and uses older graphics APIs including OpenGL and DirectX 9/10/11.
OGS is shared by nearly all Autodesk products, including Inventor, Revit, 3ds max, AutoCAD, Maya, Fusion, Infraworks, Navisworks and Recap. The new viewport system is a complete re-architecting of the current One Graphics System (OGS), which relies solely on rasterisation, a rendering method for 3D software that takes vector data and turns it into pixels (a raster image). The aim is to enable users to switch between a simple shaded view and a photorealistic representation very quickly – though the speed at which this can happen will depend on the graphics hardware and the complexity of the model. The ‘next-generation’ system will also improve visual quality by delivering ray tracing directly inside the viewport. Autodesk’s new One Graphics System (OGS) for Inventor, 3ds max and other Autodesk applications promises to improve viewport performance and visual quality through GPU ray tracing, writes Greg CorkeĪutodesk is working on a new graphics engine that promises to ‘radically improve’ 3D performance in its core applications, including Inventor, 3ds max, Revit and others.
