4D Gaussian Splatting for Real-Time Dynamic Scene Rendering-4DGS阅读笔记为了实现实时动态场景渲染，同时还能具备较高的训练和存储效率，作者提出了四维高斯溅射（4D-GS）方法，将其作为动态场景的一种整体表示方式，而不是对每个单独的帧应用三维高斯溅射（3D-GS）方法。在 4D-GS 中，提出了一种新颖的显式表示方法，它同时包含三维高斯模型和四维神经体素。受 HexPlane 启发，提出了一种分解的神经体素编码算法，以高效地从四维神经体素构建高斯特征，然后应用一个轻量级多层感知器（MLP）来预测在新时间戳下的高斯变形。阅读详情

小弟用的是 Dell D630（显卡是 NVidia Quadro NVS 135M）装的驱动是 197.16 系统： Xp sp3

在用 opengl 时基本上不支持 Opengl 扩展，不知道是显卡确实不支持，还是有什么设置不正确，求解答。

通过 glGetString 函数得到如下信息：

GL_VENDER "NVIDIA Corporation"
GL_VERSION "3.2.0"
GL_GL_EXTENSIONS "GL_EXT_bgra GL_WIN_swap_hint "
GL_RENDERER "Quadro NVS 135M/PCI/SSE2"

还有通过 glew 中的 glewInfo 得到如下信息：

GL_ARB_framebuffer_object: OK [MISSING]
--------------------------
glBindFramebuffer: OK
glBindRenderbuffer: OK
glBlitFramebuffer: OK
glCheckFramebufferStatus: OK
glDeleteFramebuffers: OK
glDeleteRenderbuffers: OK
glFramebufferRenderbuffer: OK
glFramebufferTexture1D: OK
glFramebufferTexture2D: OK
glFramebufferTexture3D: OK
glFramebufferTextureLayer: OK
glGenFramebuffers: OK
glGenRenderbuffers: OK
glGenerateMipmap: OK
glGetFramebufferAttachmentParameteriv: OK
glGetRenderbufferParameteriv: OK
glIsFramebuffer: OK
glIsRenderbuffer: OK
glRenderbufferStorage: OK
glRenderbufferStorageMultisample: OK

GL_ARB_framebuffer_sRGB: MISSING
------------------------

GL_ARB_geometry_shader4: OK [MISSING]
------------------------
glFramebufferTextureARB: OK
glFramebufferTextureFaceARB: OK
glFramebufferTextureLayerARB: OK
glProgramParameteriARB: OK

在下不懂 GL_ARB_framebuffer_object: OK [MISSING]
是什么意思，为什么它的子项都是 OK，但它是 OK[MISSING] , 望解答.

Thanks.

上面总结的还有点问题，今天要用cuda，但185.85驱动只支持cuda2.2，为了使用cuda3.0，我有尝试刷到了197.16，结果发现opengl扩展还是支持的，我推断，opengl扩展的支持在驱动升级中没有被复写，也就是说197.16版本中可能根本就没有关于opengl部分的。但最好在驱动升级中不要卸载原驱动。

补充说了上面的，希望对有心人有用。

原因找到了，不是opengl32.dll 的问题，是驱动的问题，最新的197.16驱动有bug，我rollback到了185.85版后没有问题了，现在也支持很多扩展。

你的开发环境中的opengl和windows的opengl是一个版本吗，会不会开发环境的opengl32.dll版本旧，你测试程序可能使用了开发环境的opengl而不是系统的opengl。

我查了下 opengl 的版本，是 5.1.2600.5512 应该是比较新的但情况还是那样

和我之前问题可能一样，系统文件夹opengl32.dll文件版本太旧。
