Description

This extension allows an application to specify a negative viewport height. The result is that the viewport transformation will flip along the y-axis.

  • Allow negative height to be specified in the Viewport::height field to perform y-inversion of the clip-space to framebuffer-space transform. This allows apps to avoid having to use gl_Position.y = -gl_Position.y in shaders also targeting other APIs.

Obsoletion by VK_KHR_maintenance1 and Vulkan 1.1

Functionality in this extension is included in VK_KHR_maintenance1 and subsequently Vulkan 1.1. Due to some slight behavioral differences, this extension must not be enabled alongside VK_KHR_maintenance1, or in an instance created with version 1.1 or later requested in ApplicationInfo::apiVersion.
