A monkey head model displayed as a quad wireframe in Tridi Viewer — Source wireframe. View the wireframe preserved from the source model.

An imported mechanical CAD assembly displayed with visible edges in Tridi Viewer — B-rep edges. Display boundary-representation edges for CAD inspection.

An animated Triceratops skeleton with its animation clip list and playback controls visible in Tridi Viewer — Animation playback. Choose a clip and inspect the asset in motion.

A 3D model displayed using a render pass in Tridi Viewer — Render passes. Inspect surface data using the available render passes.

A textured model and its UV map displayed side by side in Tridi Viewer — Built-in UV map display. Inspect UV0 and UV1 alongside the selected object.

Key features

A closer look at every part of your model.

Tools for inspecting, editing, rendering, and exporting 3D assets.

Real-time PBR rendering powered by Filament

Filament uses rasterized rendering, the approach common in modern game engines and WebAR, for fast physically based results.
Wide format support: glTF, FBX, OBJ, USD, Alembic, CAD, and more

Open 3D files directly from File Explorer without launching a heavy 3D app.
Built-in UV map display

Display UV0 and UV1 in the built-in UV workspace while keeping the selected object synchronized.
Original wireframe preservation

Review the wireframe preserved from the source model.
Material and texture editing with automatic texture assignment

Edit materials and textures to create model variants, then export them with textures connected.
Diagnostic views for materials, textures, map passes, and UVs

Switch views to investigate the data behind the final render.
Animation playback with skinning and morph support

Play clips and inspect animated characters in motion.
Object hierarchy with visibility, isolate, selection, and focus controls

Navigate complex scenes with direct control over their objects.
High-resolution PNG/JPEG rendering with post-processing and supersampling

Create polished stills for presentations, reviews, and documentation.
Export full, visible, or selected models to glTF/GLB or OBJ

Choose the scene scope and format that fits your next workflow.
Native touchscreen support

Use Tridi Viewer comfortably on touchscreen Windows devices.
And more.

Tridi Viewer is still in development, with more features coming while performance remains a priority.

System requirements

A current x64 Windows workstation.

Operating system

Windows 10 version 1809 or newer, or Windows 11.

Architecture

x64. ARM64 and x86 packages are not currently available.

Graphics

An up-to-date Vulkan-capable driver is preferred; Tridi can fall back to OpenGL.

Dense geometry, large scenes, and high-resolution textures require more system and graphics memory. Complex files can also take longer to open.

Availability

Tridi Viewer is now in public beta.

The public beta is available now, with ongoing improvements to features and format support.

Documentation applies to Tridi Viewer 1.1.3 public beta. See release notes.
