VkDepthClampModeEXT

Possible values of VkPipelineViewportDepthClampControlCreateInfoEXT::depthClampMode, specifying which range should be used for depth clamping, are:

typedef enum VkDepthClampModeEXT {
    VK_DEPTH_CLAMP_MODE_VIEWPORT_RANGE_EXT = 0,
    VK_DEPTH_CLAMP_MODE_USER_DEFINED_RANGE_EXT = 1,
} VkDepthClampModeEXT;

pub struct DepthClampModeEXT(u32);
impl DepthClampModeEXT {
    pub const VIEWPORT_RANGE: Self = 0;
    pub const USER_DEFINED_RANGE: Self = 1;
}

• VK_DEPTH_CLAMP_MODE_VIEWPORT_RANGE_EXT specifies that the depth clamp range follows the viewport depth range. The depth clamp range of each viewport will implicitly be set to z_min = min(n,f) and z_max = max(n,f), where n and f are the minDepth and maxDepth depth range values of the viewport.
• VK_DEPTH_CLAMP_MODE_USER_DEFINED_RANGE_EXT specifies that a single user-defined depth clamp range will be used for all viewports. The user-defined depth clamp range is defined by the minDepthClamp and maxDepthClamp members of VkDepthClampRangeEXT.
