User Friendly Interface

3D Rendering Software for Everyone


You can use Light Tracer to create stunning renderings for any purpose and industry — whether you are a professional working in a commercial environment, a hobbyist working on a personal project, or a student. The rendering software allows you to quickly produce amazing visuals of your automotive projects, product designs, architecture visualization, jewelry projects, and more.

Real-time Rendering


Light Tracer software reacts to all scene changes interactively making designing of your products an easy and fun process. All the adjustments of materials, lights and object positions are immediately visible as real-time feedback in the viewport, which always displays the final rendering result. With Light Tracer, what you see is what you get without any compromises.

Unique Render for any Platform


Light Tracer can run probably on any GPU produced after 2013 (please download the latest drivers!). Moreover, it can run directly in a Web browser delivering uncompromised rendering quality on any compatible device on Web. As a result, you may export your artwork from the native version and showcase it interactively in a Web browser!

Real-time Rendering

Rendering / Software features

These are some of the most relevant features of Light Engine

3d rendering online

Client-side Web rendering

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

physically based rendering

Physically-based GPU engine

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

gpu rendering

Fast and efficient

A highly optimized ray tracing engine provides interactive feedback to all your changes. Dynamic modifications of large scenes made possible by rapid updates to the acceleration structures


progressive refinement path tracing

Progressive refining

Light Tracer software 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

materials and textures

Powerful material workflow

Our rendering software 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 sources

Lights system

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


shadow catcher

Shadow catcher

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

backplate image

Backplates

Enhance your product renderings with custom backplate images or visualize them using a transparent background to finalize composition later

material presets

Material library

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


AI denoising

AI denoising

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 STEP IGES

File import

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

native version

Native version

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

FAQ

Frequently Asked Questions

Is Light Tracer Render biased or unbiased?

Our 3D rendering software 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.

Is Light Tracer Render RGB or spectral?

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.

Does Light Tracer use CPU, GPU, or both?

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).

Which GPUs are supported?

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.

How fast is 3D rendering software in comparison to others?

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, the 3D rendering software provides very important advantage: it can run directly in a Web browser delivering uncompromised rendering quality on any compatible device.

In what areas can Light Tracer Render be used?

Our 3D rendering software is designed to meet the needs of engineers, designers, and architects. Light Tracer can be used in the fields of Product Design, Interior Design, Advertising, Jewelry Design, Online Configurators and 3D Viewers, Architectural Visualization and Industrial Design. In just a few steps, apply stunning effects, add textured materials to get beautiful and truly realistic results.

Can I use Light Tracer engine in my own products?

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 info@lighttracer.org for details.
