Mesa 18.2.2发布下载，3D图形库开源集合_Linux软件

Mesa 18.2.2 发布下载了，它修复了很多已知的BUG，Mesa 18.2.2 实现了 OpenGL 4.5 API，但 glGetString（GL_VERSION）或 glGetIntegerv（GL_MAJOR_VERSION）/ glGetIntegerv（GL_MINOR_VERSION）报告的版本取决于所使用的特定驱动程序。某些驱动程序不支持 OpenGL 4.5 中所需的所有功能。只有在创建上下文时请求，OpenGL 4.5 才可用。兼容性上下文可能会报告较低的版本，具体取决于每个驱动器。

Mesa简介

Mesa 是一个三维（3D）图形库的开源集合，其主要目标是在 Linux/UNIX 操作系统下实现各种 API（应用程序编程接口）和 OpenGL 规范。它面向 3D 计算机图形，硬件加速 3D 渲染和图形处理单元（GPGPU）上的通用计算。此外，该项目还提供了软件渲染的实现。
