Class KHRSamplerMirrorClampToEdge

java.lang.Object

org.lwjgl.vulkan.KHRSamplerMirrorClampToEdge

public final class KHRSamplerMirrorClampToEdge
extends java.lang.Object

VK_KHR_sampler_mirror_clamp_to_edge extends the set of sampler address modes to include an additional mode (SAMPLER_ADDRESS_MODE_MIRROR_CLAMP_TO_EDGE) that effectively uses a texture map twice as large as the original image in which the additional half of the new image is a mirror image of the original image.

This new mode relaxes the need to generate images whose opposite edges match by using the original image to generate a matching "mirror image". This mode allows the texture to be mirrored only once in the negative s, t, and r directions.

Example

Creating a sampler with the new address mode in each dimension

     VkSamplerCreateInfo createInfo =
     {
         VK_STRUCTURE_TYPE_SAMPLER_CREATE_INFO // sType
         // Other members set to application-desired values
     };
 
     createInfo.addressModeU = VK_SAMPLER_ADDRESS_MODE_MIRROR_CLAMP_TO_EDGE;
     createInfo.addressModeV = VK_SAMPLER_ADDRESS_MODE_MIRROR_CLAMP_TO_EDGE;
     createInfo.addressModeW = VK_SAMPLER_ADDRESS_MODE_MIRROR_CLAMP_TO_EDGE;
 
     VkSampler sampler;
     VkResult result = vkCreateSampler(
         device,
         &createInfo,
         &sampler);
