Package org.lwjgl.vulkan
Class IMGFilterCubic
java.lang.Object
org.lwjgl.vulkan.IMGFilterCubic
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 =
{
.sType = VK_STRUCTURE_TYPE_SAMPLER_CREATE_INFO,
// 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);
