Multi-threaded DirectX12 renderer w/ HDR, PBR & Multi-monitor support

Hi there 👋

I'm Volkan, a software engineer specializing in computer graphics, parallel & high performance computing with some video game industry experience.

I'm into science, technology, music, games and traveling around.

In computing, I'm into real-time and high-performance applications, CPU & GPU performance optimizations, realistic rendering and hardware architecture.

---

🔭 I also enjoy building stuff, currently working on VQEngine, a real-time multi-threaded DirectX12 Renderer with HDR display support

💬 Albeit rarely, I do post about programming and graphics on my technical blog.

Cheers!

vqengine's Issues

EXR file support

TODO:

• integrate: https://github.com/syoyo/tinyexr

https://github.com/vilbeyli/VQE/blob/0f2acb5737f4aa3e4f3f14015a84b6dfd893e565/Source/Renderer/Texture.cpp#L62

https://github.com/vilbeyli/VQUtils/blob/494af9b63350a594f8c8b009baf89df15c1692b5/Source/Image.cpp#L76

D3D12MA integration

• Texture/Resource creation
• Heap management
• constant buffer management

Update Build configuration: Debug/Test/Release

• Debug: usual
• Test: usual release mode with gpu markers/object names
• Release: final release mode, no markers/helpers

Fix Memory Leak from Events

delete not called after handling events...

App Icon

Limit framerate through EngineSettings.ini

depends on #18

Geometry Generator: Triangle & Cube

CPU Timer

Camera aspect ratio not updated on window resize

RendererSettings.ini

Exclusive Fullscreen startup crashes

Report system info: CPU, GPU, Monitors, RAM

• VQUtils system info implementation
• Fix linker issue when the library is used in VQE
• Print out system info

AppIcon missing when app is started borderless fullscreen

Cube Rendering

• Cube geometry
• Depth buffer
• Transformations
• constant buffer functionality
• unlit shader
• Math lib

Mouse movement depends on frame rate

Minimizing window hits assertion

Validation error on fullscreen toggle

Borderless Fullscreen window initial display window rect is not correct

Shader Reflection + Root Signature Management

http://simonstechblog.blogspot.com/2019/06/d3d12-root-signature-management.html

VSync support

Exclusive Fullscreen alt+tab recovery

Fix Startup on Fullscreen mode

Release mode IsKeyDown('W') returns true for some reason

[Bug] Packaged build exclusive fullscreen won't work

Alt+Enter system error sound is annoying and should be muted

https://stackoverflow.com/questions/3662192/disable-messagebeep-on-invalid-syskeypress

Alt+F4 exit hits assertion: SwapChain backbuffer cannot be created

Environment map rendering

• Cubemap generation
• Environment map shader
• Environment map wrapper

[Build] Fix packaging script to exclude *.lib files in package directory

CTRL / SHIFT key presses gets input state stuck

[Build] Remove CMAKE_PLATFORM_GENERATOR from lists to fix Visual Studio CMake integration

HDR SwapChain support

Handle Fullscreen + Window Resizing

Generic Multi-window management

To be done after some shadowing lights are supported.

Until then, Main + Debug window will be the only two windows.

TODO

• Shadow Views on dedicated windows

EngineSettings.ini

App crash when window width or height is 0, warnings/errors when smaller than 8

PostProcess: Tonemap + Color Transfer

• Scene to its own FP16 RT
• Tonemap CS
• Color Transfer header + shader

MSAA

Mouse isn't hidden upon capture during exclusive fullscreen transition

Textures + Loading Screen Rendering

Hello Triangle

Fullscreen swapchain starts with specified lower matching resolution instead of the display rect

AppIcon missing when app is started Exclusive fullscreen

Multiple windows registering for Raw Input breaks Mouse Input events

Mouse isn't captured when debug window is not initialized

Keyboard/Mouse Input

Remove Exclusive fullscreen setting/mode and use borderless as the default fullscreen mode

Reasonsing

• When Exclusive fullscreen changes the resolution, the display mode is changed
• Alt+Tab transitions are slow
• Application exit is slow due to SetFullscreen() call
• There's no added benefit in supporting exclusive fullscreen
• The only time the user will have to do extra work is when the monitor has different refresh rate support for different resolutions.
  • Example
    • 2160p@60FPS
    • 1440p@144FPS
  • The user would have to change the display settings themselves before launching the app

ImGUI integration

• ImGUI integration
• Basic Layout / control windows
• Mouse input
• Engine Game mode vs UI mode capture
• Deferred events from UI dropdowns: scene load, env map load
• Profiler FPS sliding average
• Profiler frame time chart

Setup continuous testing on AppVeyor

• Command line parameter
• setup AppVeyor

Update Readme for v0.1.0 - Hello Triangle

Geometry Generator: Sphere, Cylinder, Cone, Quad, Tessellated Quad

• Math library
