smaa-cpp
An implementation of Enhanced Subpixel Morphological Antialiasing (SMAA) written in C++
Requirements
- CMake (>= 3.1)
- libpng (optional, needed for tests and example)
Building
mkdir build
cd build
cmake path/to/source
make
sudo make install
API Overview
The folloing two classes are provided. See header files and example (bin/smaa_png.cpp) for more details.
PixelShader class
Pixel shaders similar to the original SMAA implementation:
| smaa-cpp | original HLSL |
|---|---|
| SMAA::PixelShader::lumaEdgeDetection() | SMAALumaEdgeDetectionPS() |
| SMAA::PixelShader::colorEdgeDetection() | SMAAColorEdgeDetectionPS() |
| SMAA::PixelShader::depthEdgeDetection() | SMAADepthEdgeDetectionPS() |
| SMAA::PixelShader::blendingWeightCalculation() | SMAABlendingWeightCalculationPS() |
| SMAA::PixelShader::neighborhoodBlending() | SMAANeighborhoodBlendingPS() |
ImageReader class
This is used for defining getPixel() member function as a callback.
Platforms
