Whats new in DELTAGEN 2021x

Core Functionalities

DELATGEN Feature - Shadow baking - interior

Bake shadows at the speed of light with the Stellar render engine. An optimized UV unwrapper, specifically designed for shadow-map generation, adds an uncanny level of realism to product models. To save even more time, when an update to a model is made, shadows only need to be baked for the added or revised part, while all pre-existing shadows require no additional recalculation. This streamlined approach complements a workflow with the perfect shadow solution – even when working with PDMXML files.

DELATGEN Feature - Lightweight VR application

With the robust Stellar render engine, DELTAGEN can output stunning stereo panoramas. 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.

Complicated data sets have met their match with DELTAGEN’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 textures can be authored further in DELTAGEN & HUB. They can also be prepared for VR, AR or other experiences in game engines using the 3DEXCITE Direct Unity® plugin.

3DEXCITE Deltagen xpdmxml support - Corvette rear

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, UVs, materials, metadata and complete assembly structures. Simplify processes and focus more on the work you love, and less time worrying about file compatibility.

Render passes are also available in 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 utilize distributed rendering.

DELTAGEN’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.

3DEXCITE Deltagen jacketing wireframe comparsion

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.

DELTAGEN - Converter Module

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.

DELTAGEN - Scale Module

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.

DELTAGEN - Analyzer Module

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.

DELTAGEN - Immersive Module

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.

DELTAGEN - Xplore module

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.
