# Base Docker Image with Compiled Pixar USD Toolchain

# This Docker image serves as a base with a precompiled version
# of the Pixar USD toolchain. It is a separate image because
# USD tools take a significant amount of time to build and
# are not updated frequently. PLATTAR uses this base for various
# open-source projects, including the xrutils toolchain.

# For more information on USD tools, visit https://github.com/PixarAnimationStudios/USD
