Khronos Standard: glTF

RevitTrueGltf

RevitTrueGltf is advanced, open-source Revit to glTF 2.0 exporter plugin built for both high-fidelity rendering and full BIM data integration. It faithfully preserves PBR materials and complete element parameters, bridging the gap between Revit authoring and modern 3D engines (e.g., Babylon.js, Three.js) for Digital Twins and O&M workflows.

Vulkan glTF PBR Path Tracer (vk_gltf_renderer)

A developer-oriented open-source Vulkan glTF 2.0 RTX path tracer with PBR materials, a wide range of glTF extensions, AI denoising (DLSS RR and OptiX), a raster preview and a built-in scene editor. It also offers tooling, including a GPU profiler, monitor, and memory stats, as well as tunable renderer settings.

KTX2Viewer

KTX2Viewer was created to provide an open-source cross-platform SDR + HDR viewer that allows developers and artists to accurately visualize KTX2 textures. The project aims to extend RenderDoc and VSCode's glTF plugin. Users will have access to information such as channels, alpha blending, mipmap visualization, and tonemapping to interact with.

X_ITE

X_ITE X3D Browser, view and manipulate X3D, VRML, glTF and other 3D sources in HTML.

Castle Model Viewer

Viewer for 3D and 2D model formats supported by the Castle Game Engine: glTF, X3D and more. Examine or walk in the virtual world with collisions, gravity, animations, sensors, shadows, mirrors, shaders and more. View it from multiple cameras at once. Take screenshots with various options (transparent background, cube maps). You can also convert between Castle Model Viewer

Castle Game Engine

Cross-platform (desktop, mobile, console, web) 3D and 2D game engine featuring a visual editor. Supports open standards like glTF, X3D, IFC and more. Fast clean code using modern Object Pascal. Free and open-source.

gltf-builder

JS library for building glTF models programmatically. It aims to make procedural generation easier by letting you build up a model piece-by-piece without having to worry about the structure of the glTF file format itself.

GLB 2 PNG

API to generate images of your 3D models directly from a URL from any angle quickly and easily.
