C Specification
The VkConditionalRenderingBeginInfoEXT structure is defined as:
// Provided by VK_EXT_conditional_rendering
typedef struct VkConditionalRenderingBeginInfoEXT {
VkStructureType sType;
const void* pNext;
VkBuffer buffer;
VkDeviceSize offset;
VkConditionalRenderingFlagsEXT flags;
} VkConditionalRenderingBeginInfoEXT;
Members
-
sTypeis a VkStructureType value identifying this structure. -
pNextisNULLor a pointer to a structure extending this structure. -
bufferis a buffer containing the predicate for conditional rendering. -
offsetis the byte offset intobufferwhere the predicate is located. -
flagsis a bitmask of VkConditionalRenderingFlagsEXT specifying the behavior of conditional rendering.
Description
If the 32-bit value at offset in buffer memory is zero, then the
rendering commands are discarded, otherwise they are executed as normal.
If the value of the predicate in buffer memory changes while conditional
rendering is active, the rendering commands may be discarded in an
implementation-dependent way.
Some implementations may latch the value of the predicate upon beginning
conditional rendering while others may read it before every rendering
command.
