tinyrenderers

Single header implemenations of Vulkan and D3D12 renderers

Features

• Single header for Vulkan renderer
• Single header for D3D12 renderer
• Texture upload + mipmap generation (better quality resizer coming soon)
• Simplified API shared between both renderers
• C style structs
• Support for Vulkan layers
• Configurable swapchain multi-sample
• Configurable swapchain imagecount
• Configurable swapchain depth/stencil attachment
• Samples use GLFW
  • GLFW
    • Works for both Vulkan and D3D12 - renderer takes over after window handle is obtained
    • Image loading done via stb_image
• Includes basic compute samples
• Uses CMake
• ...more to come soon

Notes

• Linux and Windows only for the moment
  • Tested on open source intel driver on Linux
  • Tested on AMD and NVIDIA drivers on Windows
  • For best results, use latest drivers
• Vulkan renderer will work with C/C++
  • For best results, use latest version of Vulkan SDK
• D3D12 render requires C++
• Microsoft's C compiler doesn't support certain C11/C99 features, such as VLAs (so alot of awkward array handling)
• tinyvk/tinydx is written for experimentation and fun-having - not performance
• For simplicity, only one descriptor set can be bound at once
  • In D3D12, this means two descriptor heaps (CBVSRVUAVs and samplers)
  • For Vulkan shaders the 'set' parameter for 'layout' should always be 0
  • For D3D12 shaders the 'space' parameter for resource bindings should always be 0
• Vulkan like idioms are used primarily with some D3D12 wherever it makes sense
• For Vulkan, host visible means both HOST VISIBLE and HOST COHERENT
• Bring your own math libraary
• Development was done on Cinder but renderers are not limited to it

Compiling and Linking

In one C/C++ file that #includes the renderer's header file, do this:

#define TINY_RENDERER_IMPLEMENTATION
#include "tinyvk.h"

or

#define TINY_RENDERER_IMPLEMENTATION
#include "tinydx.h"

Change Log

[2017/11/12] - Added simple tessellation shader sample. Fixed misc issues with pipeline setup for tessellation. [2017/11/10] - Added ChessSet demo. Added geometry shader sample. Fixes to depth stencil handling. [2017/11/10] - Added TexturedCube sample. Updated depth attachment handling on swapchain render pass. Switched out lc_image for stb_image. Added DXC shader build script. [2017/05/27] - Fixed some annoying buffer state transitions. Added build script for shaders. Updated shader naming convention to be more exact. Added OpaqueArgs and PassingArrays for investigation.
[2017/05/20] - Updated Append/Consume sample for Vulkan. Requires latest glslang. ConstantBuffer also works for both platforms.
[2017/05/13] - Added Linux support. Moved to project files to cmake. Moved glsl shaders to glsl sub directory - forcing HLSL for now.
[2017/04/30] - Clarified shader usage in some sample programs to point out which source they're coming from.
[2017/04/27] - Added ConstantBuffer sample (D3D12 only for now). Updated Vulkan samples to use negative viewport height.
[2017/04/25] - Updated SimpleCompute and StructuredBuffer to work on Vulkan.
[2017/04/24] - Added compute samples (D3D12 only for now). One for simple compute and another for structured buffers.
