      long optimalBufferCopyOffsetAlignment()

      long optimalBufferCopyRowPitchAlignment()
      Returns:
      the optimal buffer row pitch alignment in bytes for vkCmdCopyBufferToImage and vkCmdCopyImageToBuffer.

    • pointSizeGranularity

      float pointSizeGranularity()

      VulkanPointSizeRange pointSizeRange()
      Returns:
      the range [minimum,maximum] of supported sizes for points. Values written to variables decorated with the PointSize built-in decoration are clamped to this range.

      Returns:
      a bitmask1 of VkSampleCountFlagBits indicating the sample counts supported for all 2D images created with VK_IMAGE_TILING_OPTIMAL, usage containing VK_IMAGE_USAGE_SAMPLED_BIT, and a non-integer color format.

    • sampledImageDepthSampleCounts

      int sampledImageDepthSampleCounts()
      Returns:

    • sampledImageStencilSampleCounts

      int sampledImageStencilSampleCounts()
      Returns:
      a bitmask1 of VkSampleCountFlagBits indicating the sample supported for all 2D images created with VK_IMAGE_TILING_OPTIMAL, usage containing VK_IMAGE_USAGE_SAMPLED_BIT, and a stencil format.

    • sparseAddressSpaceSize

      long sparseAddressSpaceSize()
      Returns:
      the total amount of address space available, in bytes, for sparse memory resources. This is an upper bound on the sum of the size of all sparse resources, regardless of whether any memory is bound to them.

    • standardSampleLocations

      boolean standardSampleLocations()
      Returns:
      specifies whether rasterization uses the standard sample locations as documented in Multisampling. If set to VK_TRUE, the implementation uses the documented sample locations. If set to VK_FALSE, the implementation may use different sample locations.

    • storageImageSampleCounts

      int storageImageSampleCounts()
      Returns:
      a bitmask1 of VkSampleCountFlagBits indicating the sample counts supported for all 2D images created with VK_IMAGE_TILING_OPTIMAL, and usage containing VK_IMAGE_USAGE_STORAGE_BIT.

    • strictLines

      boolean strictLines()
      Returns:
      specifies whether lines are rasterized according to the preferred method of rasterization. If set to VK_FALSE, lines may be rasterized under a relaxed set of rules. If set to VK_TRUE, lines are rasterized as per the strict definition.

    • subPixelInterpolationOffsetBits

      int subPixelInterpolationOffsetBits()
      Returns:
      the number of subpixel fractional bits that the x and y offsets to the InterpolateAtOffset extended instruction may be rounded to as fixed-point values.

    • subPixelPrecisionBits

      int subPixelPrecisionBits()
      Returns:
      the number of bits of subpixel precision in framebuffer coordinates xf and yf.

    • subTexelPrecisionBits

      int subTexelPrecisionBits()
      Returns:
      the number of bits of precision in the division along an axis of an image used for minification and magnification filters. 2subTexelPrecisionBits is the actual number of divisions along each axis of the image represented. Sub-texel values calculated during image sampling will snap to these locations when generating the filtered results.

    • timestampComputeAndGraphics

      boolean timestampComputeAndGraphics()
      Returns:
      specifies support for timestamps on all graphics and compute queues. If this limit is set to VK_TRUE, all queues that advertise the VK_QUEUE_GRAPHICS_BIT or VK_QUEUE_COMPUTE_BIT in the VkQueueFamilyProperties::queueFlags support VkQueueFamilyProperties::timestampValidBits of at least 36.

    • timestampPeriod

      float timestampPeriod()
      Returns:
      the number of nanoseconds required for a timestamp query to be incremented by 1.

    • viewportBoundsRange

      VulkanViewportBoundsRange viewportBoundsRange()
      Returns:
      the [minimum, maximum] range that the corners of a viewport must be contained in. This range must be at least [-2 × size, 2 × size - 1], where size = max(maxViewportDimensions[0], maxViewportDimensions[1]). The intent of the viewportBoundsRange limit is to allow a maximum sized viewport to be arbitrarily shifted relative to the output target as long as at least some portion intersects. This would give a bounds limit of [-size + 1, 2 × size - 1] which would allow all possible non-empty-set intersections of the output target and the viewport. Since these numbers are typically powers of two, picking the signed number range using the smallest possible number of bits ends up with the specified range.

    • viewportSubPixelBits

      int viewportSubPixelBits()
      Returns:
      the number of bits of subpixel precision for viewport bounds. The subpixel precision that floating-point viewport bounds are interpreted at is given by this limit.
