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.
