@ -152,15 +152,6 @@ DMA needs to be initialized, which will be done in the `setup()` function:
#endif
~~~~
When using DMA, memory buffer mapping is done through the DMA interface (instead of the VKDevice).
Therefore, change the lines at the end of `updateUniformBuffer()` to use the common allocator interface.
~~~~ C++
void* data = m_alloc.map(m_cameraMat);
memcpy(data, &ubo, sizeof(ubo));
m_alloc.unmap(m_cameraMat);
~~~~
The RaytracerBuilder was made to allow various allocators, therefore nothing to change in the call to `m_rtBuilder.setup()`
