romualdo97 / Vulkan02_CreatingCommandBufferAndPresenting.cpp
Created July 19, 2024 14:01
Snippet from Vulkan and Unreal VulkanRHI studies outlining a command buffer that clears an image and is submitted into GPU for processing then the result is presented, this will become more abstract as we advance in the RHI API studies, here we see the plain Vulkan API
void FVulkanDynamicRHI::DoExperimentsSetup()
{
// Create a swap chain and its surface
std::vector<VkImage> Images;
const FVulkanSwapChain SwapChain{Instance, *Device, GetWindowHandle(), 300, 300, Images};
// Create a command memory pool
const VkCommandPoolCreateInfo CommandPoolCreateInfo

The volkano project core

This class is basically a rudimentary state machine, the states are set by calling rightVolcanRotate(), rightVolcanStop(), leftVolcanRotate(), and leftVolcanStop(). Those methods are invoked by the leap motion unity SDK (4.5.0)

https://developer.leapmotion.com/unity#5436356

The leap motion SDK exposes some unity events for some gestures, eg: left hand opened, right hand opened, the Animation's methods are invoked when those events happens. For more details I recommend to play around with the leap sdk.
