问题描述

是否可以从Vulkan渲染到OpenGL?

Is it possible to render to OpenGL from Vulkan?

nVidia似乎有一些东西: https://lunarg.com/faqs/mix-opengl-vulkan-rendering/

It seems nVidia has something: https://lunarg.com/faqs/mix-opengl-vulkan-rendering/

可以为其他GPU做到吗?

Can it be done for other GPU's?

推荐答案

NVIDIA创建了OpenGL扩展NV_draw_vulkan_image，可以在OpenGL中渲染VkImage.它甚至具有一些与Vulkan信号灯等进行交互的机制.

NVIDIA has created an OpenGL extension, NV_draw_vulkan_image, which can render a VkImage in OpenGL. It even has some mechanisms for interacting with Vulkan semaphores and the like.

但是，根据文档，您必须绕过所有Vulkan图层，因为这些图层可以修改不可调度的句柄，并且OpenGL扩展不知道所述修改.他们推荐的方法是对所有Vulkan函数使用glGetVkProcAddrNV.

这也意味着您无法访问任何依赖Vulkan层的调试.

Which also means that you can't get access to any debugging that relies on Vulkan layers.
