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 1.6.0 is available.

This website and documentation describe the current Tridi 1.6.0 release.
