Whats new in DELTAGEN 2018x

Perfect Shadow Baking

Shadow baking receives a major boost in DELTAGEN 2018x, and can now be calculated up to two-times as fast, with the Stellar render engine. An optimized UV unwrapper, specifically designed for shadow-map generation, unlocks incredible shadow quality that adds an uncanny level of realism to product models. To further save time, when an update to a model is made, shadows only need to be baked for the added or revised part, all pre-existing shadows don’t require recalculation. This streamlined approach complements a workflow with the perfect shadow solution – even when working with PDMXML files.

Lightweight VR


To further expand horizons in this digitally driven world, DELTAGEN 2018x can output stereo panoramas with the STELLAR render engine. The combination of Global Illumination and STELLAR’s Physically Based Renderer supports the creation of visually unmatched VR content that can be ported through any VR ready headset. Stellar’s advanced render settings can also be leveraged to output multiple passes and generate scene variants for use directly in VR experiences. The power of immersive, lightweight VR is in your hands.

Boost Performance

Complicated data sets have met their match with DELTAGEN 2018x’s Model Optimizer. Massive performance improvements can be gained through the optimizer’s automatic search and deletion of unnecessary part groups and the reduction of a scene-tree’s depth. Hardware requirements can be reduced by decreasing the scene’s shape count, by combining objects with the same material values. Shadow maps can also be aggregated into large texture atlases to reduce the file count and overhead of unused areas on a shadow texture. Aggregated shadow texures can be authored further in DELTAGEN 2018x & DELTAGEN HUB. They can also be prepared for VR, AR or other experiences in game engines using the 3DEXCITE Direct Unity® plugin.

Native Goniometric Lighting

Our 3DEXCITE STELLAR renderer is now more powerful than ever, thanks to its enhanced ability to process reflections, and its native support of goniometric lights. With the DELTAGEN 2018x’s STELLAR update, it’s possible to define the parts of the model you want to evaluate reflections for, focusing render time on a specific area and facilitating faster reviews with a single workstation, even in Rasterizing mode.
Enjoy more accurate and beautiful lighting, using DELTAGEN 2018x’s support for goniometric lights. Simply customize lighting settings and import your .ies files directly to DELTAGEN, or adjust the settings in DELTAGEN’s Object Editor to achieve unprecedented lighting control in all render modes.



The CG workflow is instantly streamlined and upgraded with DELTAGEN’s native support of XPDMXML files straight from CAD software. Further linking DELTAGEN to the power of the Dassault Systèmes 3DEXPERIENCE® platform, directly import CAD files that include model parts with NURBS, metadata and complete assembly structures. Simplify processes and focus more on the work you love, and less time worrying about file compatibility.

Powerful Polygon Reduction

Significantly reduce the polygon count of models without losing visual quality using the new polygon decimator. When used in conjunction with the Model Optimizer, data can be quickly and easily prepared for gaming engine plugins to create stunning desktop, mobile, immersive experiences and beyond. Further extend the significance of all digital assets with this new functionality..


Render passes are also available in DELTAGEN STELLAR and Distributed STELLAR (DSTELLAR). They include: Diffuse, Specular, Refraction, Reflection, Indirect Illumination, Ambient Occlusion, UV, Normal, Depth, Alpha and STELLAR Material ID. Render passes in DSTELLAR extend the capabilities of large content production pipelines that are using distributed rendering.

Improved Automatic Unwrapping

DELTAGEN 2018x’s powerful Automatic Unwrapping feature provides perfect texturing without visible seams, allowing for full material coverage. The result is smooth, gorgeous textures that are indistinguishable from their real-world counterparts. Shadow UVs also feature automatic unwrapping, making your texturing smoother, more inutitive and higher quality with less effort.

Jacketing Configurator


Save time, effort and achieve better model reduction results with refined jacketing techniques. Define occluders per group or part – rather than by isolating parts one by one – and quickly compare results from different quality settings to determine how to best prepare your data.

DELTAGEN Plug-In Modules

Enhance the DELTAGEN functionality with highly specialized modules for your individual use case.

Regardless of whether you work together with draughtsmen, product designers or 3D artists: You can open their files simply and directly in DELTAGEN. A multitude of converters ensures that our applications cooperate seamlessly with all established CAD systems.

Alongside useful functions, such as the automatic correction of surface normals, there are tools available that allow simple structuring of your files.

No need to compromise any longer: Now you can render complex scenes at high speed with high quality. Scale allows the computer to control computing units in other workstations via a network and thus divide rendering jobs into packages and allocate them to all the available units. This focuses optimal resources on each task and large data volumes can be processed without having to make compromises in terms of quality.

The standard scaling module for DELTAGEN supports up to two GPUs and two CPUs; this capability can be extended to as many as required in order to have flexibility with the presentation medium – from individual monitors up to powerwalls. Scale provides breathtaking results, great efficiency and prime utilization of hardware resources.

Layercreator automates the rendering of high-end 3-D visualizations and increases the speed, flexibility and efficiency of your work. Organize models, environments and effects easily with image layers.Edit them individually, create custom combinations and display or hide them.

A push of the button is all it takes to output layers of flash films for postproduction, for images andfor film creation in websites or configuration systems. Layercreator enables users to automate and structure work with flexibility. With a greater range of variants, increased productivity and top-quality images, the proof is in the results.

Make use of the possibilities provided by Analyzer in order to carry out and produce quick, intuitive and exact geometry analysis, survey measurements and sections. Determine and visualize all the important information required for the clear and comprehensible presentation of designs.

This optional measurement module for DELTAGEN can be used to ascertain distances between points or the geometry of objects, and to create sections through all desired layers to compare models. Do away with time consuming measurement protocols – Analyzer provides a comprehensive and secure view of all the required information.

Dive deep into the virtual world and experience 3D realtime models created by DELTAGEN in three dimensional space. Explore, test and present designs interactively from every angle. Make use of a VR head mounted displays or utilize a PC cluster and Scale to provide angularly configured powerwalls and projection environments (CAVEs).

The integrated tracking function transmits movement to the camera controls, which allows subjects to navigate through the model and interact with objects. Immersive also allows a dynamic collision detection of animated or tracked objects. In the process, access other modules and, for example, start animations, turn variants ‘on or off’ and create sections. With this approach, making virtual reality part of everyday work is intuitive and feasible.

Present the realtime scene professionally – for product reviews or marketing and sales use cases. Multi-touch navigation makes interacting with a scene as easy as browsing a web page with full variant control and a wide array of features. XPLORE DELTAGEN ensures a perfect presentation scenario and seamless interactions with an audience. Facilitate validation processes and speed up decision-making with direct control of the scene being displayed. XPLORE elevates a product presentation directly from a tablet or mobile device.

Our Customers Trust in DELTAGEN

3DEXCITE technology has allowed us to close the gap between engineering and the marketing world. Scaling a very complex train configurator project into something suitable for a large audience - internal and external to the company - was very successful.  DELTAGEN offers huge flexibility when working with the master model and represents a key activity of Alstom.
