问题描述
我是Vulkan的新手，最近开始学习.
I am new to Vulkan, and recently started learning .
我正面临一个问题，当启用
VkPhysicalDeviceFeatures 时，在 vkCreateDevice()中运行失败
I am facing issue, at runtime in vkCreateDevice() fails, when VkPhysicalDeviceFeatures is enables with
当features.wideLines = VK_FALSE时；vkCreateDevice()创建成功，但是我无法使用-vkCmdSetLineWidth(command_buffer，line_width)修改LineWidth.这给了我
And when features.wideLines = VK_FALSE; vkCreateDevice() creations is successful, but I am not able to modify the LineWidth using - vkCmdSetLineWidth (command_buffer, line_width); this gives me
这是一些细节-
VkPhysicalDeviceFeatures:
VkPhysicalDeviceFeatures:
geometryShader = false
wideLines = false
lineWidthRange: count = 2
1
1
lineWidthGranularity = 1
strictLines = false
我在Vulkan文档中/在Google上进行了一些搜索，但找不到任何报告类似问题的人.任何帮助将不胜感激.
I did some searches in Vulkan Documentation/on google, but couldn’t find anyone reporting a similar issue. Any help would be appreciated.
推荐答案
当您告诉其他地方，Metal不支持宽线，因此MoltenVK(金属上的Vulkan)也不能支持宽线.您将必须使用多边形手动绘制宽线.
As you were told elsewhere, Metal does not support wide-lines, so MoltenVK (Vulkan over Metal) cannot support wide lines either. You will have to render wide lines manually with polygons.
这篇关于MacOS-运行时Vulkan在vkPhysicalDeviceFeatures wideLines = VK_TURE时vkCreateDevice()失败，并且也不支持vkCmdSetLineWidth API的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
