*
|
||||
* Summary:
|
||||
* Demonstrates the use of dynamic uniform buffers.
|
||||
*
|
||||
* Instead of using one uniform buffer per-object, this example allocates one big uniform buffer
|
||||
* with respect to the alignment reported by the device via minUniformBufferOffsetAlignment that
|
||||
* contains all matrices for the objects in the scene.
|
||||
*
|
||||
* The used descriptor type VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER_DYNAMIC then allows to set a dynamic
|
||||
* offset used to pass data from the single uniform buffer to the connected shader binding point.
