EXTProvokingVertex (LWJGL 3.3.1 - Vulkan)

java.lang.Object
- org.lwjgl.vulkan.EXTProvokingVertex

```
public final class EXTProvokingVertex
extends java.lang.Object
```
This extension allows changing the provoking vertex convention between Vulkan’s default convention (first vertex) and OpenGL’s convention (last vertex).
This extension is intended for use by API-translation layers that implement APIs like OpenGL on top of Vulkan, and need to match the source API’s provoking vertex convention. Applications using Vulkan directly should use Vulkan’s default convention.

    Description
    
    PROVOKING_VERTEX_MODE_FIRST_VERTEX_EXT specifies that the provoking vertex is the first non-adjacency vertex in the list of vertices used by a primitive.
    
    PROVOKING_VERTEX_MODE_LAST_VERTEX_EXT specifies that the provoking vertex is the last non-adjacency vertex in the list of vertices used by a primitive.
    
    These modes are described more precisely in Primitive Topologies.
