Class IMGFilterCubic

java.lang.Object

org.lwjgl.vulkan.IMGFilterCubic

public final class IMGFilterCubic
extends java.lang.Object

VK_IMG_filter_cubic adds an additional, high quality cubic filtering mode to Vulkan, using a Catmull-Rom bicubic filter. Performing this kind of filtering can be done in a shader by using 16 samples and a number of instructions, but this can be inefficient. The cubic filter mode exposes an optimized high quality texture sampling using fixed texture sampling functionality.

Example

Creating a sampler with the new filter for both magnification and minification

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