Implementation of a Visibility Buffer renderer using the AMD GCN extensions. Developed as part of my honours project.

Prerequisites

• Git LFS
• Vulkan SDK and Vulkan drivers
• CMake
• Models: https://goo.gl/ajpMH0

Basic structure

Two binaries are produced:

• vksagres-deferred
• vksagres-visbuffer

One library is produced which is linked against the executables to provide common functionalities.

Cloning and building

Debug

• Clone the repository
• Download the models and unpack them in the folder assets\models\ so that the path to the model files looks like this: assets\models\model_a\modelfile.dae
• Make sure you meet the prerequisites as above
• Create a separate build folder
• Inside the build folder create a folder called debug
• Use CMake to configure and then generate the project in the debug folder
  • If using CMake GUI:
    • Change the entry CMAKE_BUILD_TYPE to Debug
    • Set the build folder to the debug folder aforementioned
  • If using CMake CLI
    • Pass -DCMAKE_BUILD_TYPE=Debug when launching CMake
    • Launch Cmake from the debug build folder
• Compile

Release

• Repeat steps for Debug but change the build type to Release and create a separate folder called release into build

Drivers

Usage

Activation and usage of performance counters

The performance counters are activated by uncommenting the lines 1201 and 1080 in visbuff/renderer.cpp and lines 1057 and 1103 in deferred/deferred_renderer.cpp. Then recompile.

Capture of a sample can be done in two ways:

1. Move the camera to the desired location, then press C
2. Press N anywhere and the application will automatically take 10 samples at predefined locations.

The captured data is located in your build folder in \perf_data.
