# This is the config file used to configure basic settings for Panda3D.
# The pipeline loads it at startup to ensure the environment is setup properly.
# Panda3D 基础设置文件，管线启动时会加载以确保环境配置正确。

pstats-max-rate 200

# No stack trace on assertion, set this to true to make panda crash on assertions
# (which will allow to debug it)
# 断言时不打印堆栈；设为 true 会在断言时直接崩溃便于调试
# assert-abort #t
# show-dll-error-dialog #f

# File system should be case sensitive
# NOTICE: Set this to #f if you are using tempfile, since it returns
# wrong cased directory paths

vfs-case-sensitive #t

# Enable state cache, this seems to actually help the performance by a lot
# 启用状态缓存，通常能显著提升性能

# Disable the annoying SRGB warning from pnmimage
# 关闭 pnmimage 的 SRGB 警告
notify-level-pnmimage error

# Disable the buffer viewer, we have our own
# 关闭内置缓冲查看器（管线自带）

# Use the default coordinate system, this makes our matrix transformations
# faster because we don't have have to transform them to a different coordinate
# system before
# 使用默认坐标系，避免矩阵转换到其他坐标系的额外开销

# This makes animations smoother, especially if they were exported at 30 FPS
# and are played at 60 FPS
