vkOceanWaves

Description

Vulkan implementation of ocean waves in both DFT and FFT

It is now basically a well organized version of Discrete Fourier Transformation Ocean Wave. The base project (base.lib) from the SaschaWillems examples codebase was used as a framework to provide a wrapper of Vulkan APIs.

You can use mouse and wheel to navigate. For now I do not set any cull mode.

Performance

It is very slowly due to the algorithm - Discrete Fourier Transform (DFT). In the latest version I update it to the Fast Fourier Transform algorithm (FFT).

Mode	FPS	Device
Debug	120+	GPU(RTX 3050Ti Laptop) / CPU(Intel i7-11800H)
Release	300~	GPU(RTX 3050Ti Laptop) / CPU(Intel i7-11800H)
Debug	120+	GPU(RTX 3070 Laptop) / CPU(AMD R7 5800H)
Release	680~950	GPU(RTX 3070 Laptop) / CPU(AMD R7 5800H)

Notice

You can select your GPU in the line 870 in .\base01\vulkanexamplebase.cpp.

869     ...
870     uint32_t selectedDevice  = 0;
871     ...

The variable selectedDevice is 1 for default. You can change it to 0 in case:

• You want to switch to another GPU
• You only have only one GPU and the program crashes at the GPU selection.
