The Light Engine technology provides you with everything you need to create photorealistic renderings interactively, in both desktop Web browsers and Windows application. GLTF, OBJ, STL, STEP, IGES formats are supported out of the box. PBR materials and Image-Based Lighting allow creating amazing visuals easily. Based on open standards, Light Engine works on all GPUs and delivers powerful ray tracing technology on both Web and native environments!
These are some of the most relevant features of Light Engine
Light Tracer is the world's first solution for GPU accelerated, photorealistic client-side rendering in desktop Web browsers. Microsoft Edge, Google Chrome and Mozilla Firefox are supported
Based on a completely physically-correct unbiased ray tracing engine working on any graphics card, both discrete NVIDIA/AMD GPUs and integrated Intel/AMD GPUs
A highly optimized ray tracing engine provides interactive feedback to all your changes. Dynamic scene modifications made possible by rapid updates to the acceleration structures
Light Tracer uses progressive rendering so that a noisy preview progressively refines to a final quality image. Just stop the rendering when the noise level is low enough
Light Tracer features a simple but robust two-layered PBR material model with the full support of metalness workflow. It allows simulating realistic surfaces, such as metal, paint, wood, stone, rubber, glass, gemstones, plastic, etc.
Light Tracer is mainly designed to use Image-Based Lighting (IBL) captured from real-world photography. Emissive meshes and analytically defined emitters are supported as well
Using the Shadow Catcher, you can easily capture shadows on a surface, while the rest of the material can remain see-through. So the scene looks like shadows cast onto the environment itself
Enhance your product visualization with custom backplate images or use a transparent background to finalize composition later
To setup scenes quickly, Light Tracer comes with a library of customizable PBR materials that can be used as prototypes and allow to get end results as soon as possible
Get final images even faster using Intel or NVIDIA AI denoisers. Or simply get almost instant noise-free previews when editing the scene. Use the built-in real-time denoiser even in the Web
Import the most common 3D formats such as OBJ, STL, (zipped) GLTF or GLB, as well as neutral STEP/IGES CAD formats. When importing from CAD, control how accurately surfaces are tessellated
Export your artwork from Light Tracer Standalone and showcase it interactively in a Web browser! Both Standalone and Web versions use absolutely the same engine ensuring identical rendering results
The 3D rendering tool is designed to meet the needs of architects and designers. Suitable for use in any field of activity, including art, advertising, architectural visualization and industrial design. Apply stunning effects, add textured materials to get beautiful and truly realistic results.

Light Tracer is based on verified unbiased rendering engine. Rendering correctness was verified by comparison with comprehensive physically-based renderers such as PBRT (https://www.pbrt.org/) and Mitsuba (https://www.mitsuba-renderer.org/). The materials are physically based and fully compatible with PBR workflow.
Given the strict requirements for working in a Web browser, the Light Tracer engine represents color with RGB values. Nevertheless, it supports spectral effects like dispersion on refractive objects.
At the same time, spectral rendering is most apparent when it is used with measured spectral data for both light sources and materials. But, in an artist-driven scene, the light source spectra are more usually reconstructed from RGB sliders in some way, leading to very smooth spectra, where it is very difficult to see actual visual differences between RGB and spectral rendering. Moreover, spectral rendering is computationally more expensive and generates more noise. For these reasons, Light Tracer is built on the RGB ray tracing engine.
The rendering process runs entirely on the GPU. The CPU is used only for the preparation of input data (in particular, accelerating structures are built and updated on a CPU). Unlike most other GPU renderers, Light Tracer is built on its own technology stack using only cross-platform GPU programming interfaces (it does not use NVIDIA CUDA, OptiX, or AMD Radeon Rays).
Light Tracer can run almost on any GPU produced after 2012 – 2013. In particular, it works fine on NVIDIA GeForce 600 series or higher, AMD Radeon RX 200 series or higher, Intel HD Graphics 4000 series or higher. At the same time, Light Tracer can utilize unique features of modern NVIDIA GPUs (if available in the system) to run GPU-accelerated AI denoising.
Light Tracer's rendering performance is comparable with the high performance GPU engines available today. Moreover, it is close to the performance of engines built for NVIDIA RTX platform. At the same time, Light Tracer provides very important advantage: it can run directly in a Web browser delivering uncompromised rendering quality on any compatible device.
Light Tracer engine is a reusable component with its own API and available for integration into both native and web applications on custom licensing terms. Please contact firstname.lastname@example.org for details.
