VkTessellationDomainOrigin

The possible tessellation domain origins are specified by the VkTessellationDomainOrigin enumeration:

typedef enum VkTessellationDomainOrigin {
    VK_TESSELLATION_DOMAIN_ORIGIN_UPPER_LEFT = 0,
    VK_TESSELLATION_DOMAIN_ORIGIN_LOWER_LEFT = 1,
} VkTessellationDomainOrigin;

or the equivalent

#define VkTessellationDomainOriginKHR VkTessellationDomainOrigin

• VK_TESSELLATION_DOMAIN_ORIGIN_UPPER_LEFT specifies that the origin of the domain space is in the upper left corner, as shown in figure xref::name::img-tessellation-topology-ul.
• VK_TESSELLATION_DOMAIN_ORIGIN_LOWER_LEFT specifies that the origin of the domain space is in the lower left corner, as shown in figure xref::name::img-tessellation-topology-ll.

This enum affects how the VertexOrderCw and VertexOrderCcw tessellation execution modes are interpreted, since the winding is defined relative to the orientation of the domain.
