Class EXTVertexAttributeDivisor

  • public final class EXTVertexAttributeDivisor
extends java.lang.Object
    This extension allows instance-rate vertex attributes to be repeated for certain number of instances instead of advancing for every instance when instanced rendering is enabled.
    Examples

    To create a vertex binding such that the first binding uses instanced rendering and the same attribute is used for every 4 draw instances, an application could use the following set of structures:

    
     const VkVertexInputBindingDivisorDescriptionEXT divisorDesc =
     {
         0,
         4
     };
 
     const VkPipelineVertexInputDivisorStateCreateInfoEXT divisorInfo =
     {
         VK_STRUCTURE_TYPE_PIPELINE_VERTEX_INPUT_DIVISOR_STATE_CREATE_INFO_EXT, // sType
         NULL,                                                             // pNext
         1,                                                                // vertexBindingDivisorCount
         &divisorDesc                                                      // pVertexBindingDivisors
     }
 
     const VkVertexInputBindingDescription binding =
     {
         0,                                                                // binding
         sizeof(Vertex),                                                   // stride
         VK_VERTEX_INPUT_RATE_INSTANCE                                     // inputRate
     };
 
     const VkPipelineVertexInputStateCreateInfo viInfo =
     {
         VK_STRUCTURE_TYPE_PIPELINE_VERTEX_INPUT_CREATE_INFO,              // sType
         &divisorInfo,                                                     // pNext
         ...
     };
     //...
