# Base Docker Image with Compiled Pixar OpenUSD Toolchain
#
# This Docker image serves as a base with a precompiled version
# of the Pixar OpenUSD 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 OpenUSD, visit https://github.com/PixarAnimationStudios/OpenUSD
