    Filament

    Filament

    Real-time physically based rendering engine for Android, iOS, and more

    ...For both artists and developers, our system will rely on as few parameters as possible to reduce trial and error and allow users to quickly master the material model. A physically based approach must not preclude non-realistic rendering. User interfaces for instance will need unlit materials. Our primary goal is to design and implement a rendering system able to perform efficiently on mobile platforms.

    Magnum

    Lightweight and modular C++11 graphics middleware for data and games

    Look­ing for an open-source lib­rary that gives you graph­ics ab­strac­tion and plat­form in­de­pend­ence on ma­jor desktop, mo­bile and web plat­forms? Do you want it to have all the con­veni­ence util­it­ies around yet stay small, power­ful and not give up on flex­ib­il­ity? Here it is. And it’s free to use, even for com­mer­cial pur­poses. Among Mag­num es­sen­tials is a UTF-8-aware OS, filesys­tem and con­sole ab­strac­tion, a ver­sat­ile vec­tor math lib­rary and a slim C++11 wrap­per of Vulkan and OpenGL API fam­il­ies. Build on top of that or opt-in for more. Shaders and prim­it­ives for fast pro­to­typ­ing, al­gorithms, de­bug­ging and auto­mat­ic test­ing, as­set man­age­ment, in­teg­ra­tion with pop­u­lar win­dow­ing toolkits and a UI lib­rary. ...

    AwesomeBump

    AwesomeBump

    Open Source graphic tool and alternative to Insane Bump

    AwesomeBump is a free and open source graphic app written using Qt library. It was made as an alternative to known gimp plugin Insane Bump or the commercial tool Crazy Bump. It is designed to generate normal, height, specular or ambient occlusion, metallic, roughness and other textures from a single image. Most of the image processing is done on GPU so the program runs very fast and all the parameters can be changed in real time.

    Imogen

    Imogen

    GPU Texture Generator

    Imogen is a real-time, node-based procedural texture generation tool aimed at artists, developers, and shader enthusiasts. It allows users to build complex material textures using a graph-based interface, combining operations like blending, noise, filters, and color correction in a non-destructive workflow. Built with Vulkan and ImGui, Imogen provides immediate visual feedback and supports GPU acceleration for high-resolution texture output. It's particularly useful in game development, VFX, and digital art where procedural workflows are valued for their flexibility and speed.

    Radiance

    Highly accurate ray-tracing software system for UNIX computers

    Radiance is a free, highly accurate ray-tracing software system for UNIX computers. It is a suite of programs designed for the analysis and visualization of lighting in design. Radiance is superior to simpler lighting calculation and rendering tools in that there are no limitations on the geometry or the materials that may be simulated. Scene geometry, materials, luminaires, time, date and sky conditions (for daylight calculations) are specified; spectral radiance (ie. luminance + color), irradiance (illuminance + color) and glare indices are calculated. ...
