C Specification
The VkIndirectCommandsLayoutCreateInfoNVX structure is defined as:
typedef struct VkIndirectCommandsLayoutCreateInfoNVX {
VkStructureType sType;
const void* pNext;
VkPipelineBindPoint pipelineBindPoint;
VkIndirectCommandsLayoutUsageFlagsNVX flags;
uint32_t tokenCount;
const VkIndirectCommandsLayoutTokenNVX* pTokens;
} VkIndirectCommandsLayoutCreateInfoNVX;
Members
-
sTypeis the type of this structure. -
pNextisNULLor a pointer to an extension-specific structure. -
pipelineBindPointis the VkPipelineBindPoint that this layout targets. -
flagsis a bitmask of VkIndirectCommandsLayoutUsageFlagBitsNVX specifying usage hints of this layout. -
tokenCountis the length of the individual command sequnce. -
pTokensis an array describing each command token in detail. See VkIndirectCommandsTokenTypeNVX and VkIndirectCommandsLayoutTokenNVX below for details.
Description
The following code illustrates some of the key flags:
void cmdProcessAllSequences(cmd, objectTable, indirectCommandsLayout, pIndirectCommandsTokens, sequencesCount, indexbuffer, indexbufferoffset)
{
for (s = 0; s < sequencesCount; s++)
{
sequence = s;
if (indirectCommandsLayout.flags & VK_INDIRECT_COMMANDS_LAYOUT_USAGE_UNORDERED_SEQUENCES_BIT_NVX) {
sequence = incoherent_implementation_dependent_permutation[ sequence ];
}
if (indirectCommandsLayout.flags & VK_INDIRECT_COMMANDS_LAYOUT_USAGE_INDEXED_SEQUENCES_BIT_NVX) {
sequence = indexbuffer.load_uint32( sequence * sizeof(uint32_t) + indexbufferoffset);
}
cmdProcessSequence( cmd, objectTable, indirectCommandsLayout, pIndirectCommandsTokens, sequence );
}
}
