allocateDescriptorSet()

bool PoolManager::allocateDescriptorSet	(	VkDescriptorSetLayout	layout,
		VkDescriptorSet &	descSet
	)

Allocates a descriptor set from the pool

Parameters

layout	Layout to be used
descSet	Descriptor set to be allocated

Returns

createPool()

VkDescriptorPool PoolManager::createPool	(	VkDevice	device,
		VkDescriptorPoolCreateFlags	flags,
		uint32_t	maxSets,
		const std::vector< VkDescriptorPoolSize > &	poolSizes
	)

Allocates a descriptor pool and adds it to the free pools.

Parameters

device	logical device
flags	flags
maxSets	maximum number of sets to be allocated from this pool
