Predict Suite

Computer Aided Appearance Design helps reducing the need for Physical Prototypes and Mockups in the Design Process

Predict Engine is a powerful rendering engine at the core of UVR’s computer-aided appearance design (CA²O) platform : the Predict Suite. Our cutting edge optical simulation engine processes data from multiple data sources (CAD drawings, BRDF, camera characterizations, spectral environments...) to create high-resolution Iso-Photographic renderings predicting with pixel-level precision how the light interacts with any object or material, in any natural or artificial environment. The Predict Suite is enriched with Predict lab, an optical analysis solution, Predict matter, an agnostic 3D asset library, and Predict sky, a light simulation tool. The Predict Suite was designed to give product manufacturers and designers a more efficient, reliable, and cost-effective way to build, test and refine prototypes and mock-ups in an interactive way.

Predict engine

Predict Engine is a compelling computer-aided appearance design renderer and enables Designers and Engineers to achieve predict rendering, which is disrupting data visualization towards iso-photography.

Predict engine core features

Spectral
Predict Engine computation is fully spectral, making light transport and material appearance accurate for all wavelength under all lighting situations. Input measures and models, output simulations and the path tracing algorithm are all spectral.
Polarization
Predict Engine computation takes polarization into account at all stages of the process (inputs, light transport and outputs), allowing for accurate reflection and transmission through all materials. Polarization is especially important when computing interactions with transparent, reflective materials or coatings, and when the light source itself is polarized (clear sky, LCD screen,...).
Unbiased and Deterministic
One can trust Predict Engine simulations thanks to its spectral and polarized path tracing algorithm. The path tracer makes no approximation on how the light propagates into the scene, making the final simulation accurate, repeatable and reliable.
Fast multi GPU rendering
Use all available Nvidia cards on your machine to get an accurate simulation within minutes or even seconds. Not enough? You can scale on a HPC GPU cluster to get there even faster!
ISO-photography
Predict Engine can simulate the behavior of a camera, or any type of optical instrument, by formally predicting a photograph. This makes virtual prototyping reliable and comparable to the ground truth: a still photograph.
Photometry and Colorimetry
Predict Engine supports CIE standard observers and color space transformation to compute accurate photometric and colorimetric quantities.
Radiometry
Generate and export multi-spectral simulation outputs to be analysed in Predict Lab. Predict Engine algorithm is always fully spectral but you can choose the format of the exported simulation.
Physical sensors
Simulate your scenes as they are seen through all types of sensors. Measure their spectral response curves and analyze the precise output of the sensors.
Global illumination
Predict Engine algorithm takes indirect light bounces into account : reflections between objects and illumination through transparent surfaces are computed accurately.
HDR
Compute and export simulations with high dynamic range data. Analyse them using Predict Lab.
Unity3D Integration
Predict Engine is fully integrated with Unity3D. Benefit from all the Unity3D features and include Predict easily into your usual Unity3D pipeline. More integration is coming soon.
XR Integration
Insert your Predict renderings and Lab analysis as a texture into real time VR or AR environments. The texture will update while the simulation converge interactively.
Live preview
Preview the simulation output and pixel information while the simulation is rendering to get an overview of the final output. Place and adjust the sensor interactively.
Additional Pixel Data
Generate and visualize additionnal pixel data about the scene such as depth, normals or material indexes and the render state such as the number of sample and the variance.
4K resolution support
Generate high definition simulations for precise analysis, 4K stereo vision, or just to get an outstanding picture !
Variants definition
Define variants in your scene to switch between predefined configurations and compare several materials, environments, models and lights.
Batch rendering
Quickly generate batch of simulations for a set of variants and viewing directions. Combine those outputs easily into physically accurate animated simulations.
Scripting
Use the power of Unity to write your own scripts and automate any part of the simulation process.
Multi-platform
The Predict Suite is fully supported on both Windows and Linux OS.
