| === Description |
| |
| This extension enables tighter array and struct packing to be used with |
| uniform buffers. |
| |
| It modifies the alignment rules for uniform buffers, allowing for tighter |
| packing of arrays and structures. |
| This allows, for example, the std430 layout, as defined in |
| https://www.khronos.org/registry/OpenGL/specs/gl/GLSLangSpec.4.60.pdf[GLSL] |
| to be supported in uniform buffers. |
| |
| === Promotion to Vulkan 1.2 |
| |
| All functionality in this extension is included in core Vulkan 1.2, with the |
| KHR suffix omitted. |
| The original type, enum and command names are still available as aliases of |
| the core functionality. |
