Valid Usage

 * 
 * 
    
 * 
  • {@code offset} must be less than the size of {@code buffer}

 * 
  • {@code offset} must be a multiple of {@link VkPhysicalDeviceLimits}{@code ::minTexelBufferOffsetAlignment}
    • 
 * 
  • If {@code range} is not equal to {@link VK10#VK_WHOLE_SIZE WHOLE_SIZE}, {@code range} must be greater than 0
    • 
 *

    • 
 * 
  • If {@code range} is not equal to {@link VK10#VK_WHOLE_SIZE WHOLE_SIZE}, {@code range} divided by the element size of {@code format} must be less than or equal to {@link VkPhysicalDeviceLimits}{@code ::maxTexelBufferElements}
    • 
 * 
  • If {@code range} is not equal to {@link VK10#VK_WHOLE_SIZE WHOLE_SIZE}, the sum of {@code offset} and {@code range} must be less than or equal to the size of {@code buffer}
    • 
 * 
  • {@code buffer} must have been created with a {@code usage} value containing at least one of {@link VK10#VK_BUFFER_USAGE_UNIFORM_TEXEL_BUFFER_BIT BUFFER_USAGE_UNIFORM_TEXEL_BUFFER_BIT} or {@link VK10#VK_BUFFER_USAGE_STORAGE_TEXEL_BUFFER_BIT BUFFER_USAGE_STORAGE_TEXEL_BUFFER_BIT}
    • 
 * 
  • If {@code buffer} was created with {@code usage} containing {@link VK10#VK_BUFFER_USAGE_UNIFORM_TEXEL_BUFFER_BIT BUFFER_USAGE_UNIFORM_TEXEL_BUFFER_BIT}, {@code format} must be supported for uniform texel buffers, as specified by the {@link VK10#VK_FORMAT_FEATURE_UNIFORM_TEXEL_BUFFER_BIT FORMAT_FEATURE_UNIFORM_TEXEL_BUFFER_BIT} flag in {@link VkFormatProperties}{@code ::bufferFeatures} returned by {@link VK10#vkGetPhysicalDeviceFormatProperties GetPhysicalDeviceFormatProperties}
    • 
 * 
  • If {@code buffer} was created with {@code usage} containing {@link VK10#VK_BUFFER_USAGE_STORAGE_TEXEL_BUFFER_BIT BUFFER_USAGE_STORAGE_TEXEL_BUFFER_BIT}, {@code format} must be supported for storage texel buffers, as specified by the {@link VK10#VK_FORMAT_FEATURE_STORAGE_TEXEL_BUFFER_BIT FORMAT_FEATURE_STORAGE_TEXEL_BUFFER_BIT} flag in {@link VkFormatProperties}{@code ::bufferFeatures} returned by {@link VK10#vkGetPhysicalDeviceFormatProperties GetPhysicalDeviceFormatProperties}

 * 
Valid Usage (Implicit)

Member documentation

 * 
 * 
    
 * 
  • {@code sType} – the type of this structure.
    • 
 * 
  • {@code pNext} – {@code NULL} or a pointer to an extension-specific structure.
    • 
 * 
  • {@code flags} – reserved for future use.
    • 
 * 
  • {@code buffer} – a {@code VkBuffer} on which the view will be created.
    • 
 * 
  • {@code format} – a {@code VkFormat} describing the format of the data elements in the buffer.
    • 
 * 
  • {@code offset} – an offset in bytes from the base address of the buffer. Accesses to the buffer view from shaders use addressing that is relative to this starting offset.
    • 
 * 
  • {@code range} – a size in bytes of the buffer view. If {@code range} is equal to {@link VK10#VK_WHOLE_SIZE WHOLE_SIZE}, the range from {@code offset} to the end of the buffer is used. If {@link VK10#VK_WHOLE_SIZE WHOLE_SIZE} is used and the remaining size of the buffer is not a multiple of the element size of {@code format}, then the nearest smaller multiple is used.
