BasicPostProcess

Performs basic post-processing with a built-in set of shaders which operate using one input texture.

Header

#include "PostProcess.h"

Initialization

Construction requires a Direct3D 11 device.

std::unique_ptr<BasicPostProcess> postProcess;
postProcess = std::make_unique<BasicPostProcess>(device);

For exception safety, it is recommended you make use of the C++ RAII pattern and use a std::unique_ptr or std::shared_ptr

Shader selection

BasicPostProcess can be configured to use various pixel shaders by calling SetEffect:

• Copy: Performs a simple read of the input texture, outputting the same color. This is mostly useful for debugging.
• Monochrome: Converts the input texture pixels to a luminance value.
• Sepia: Implements a sepia-tone effect.
• DownScale_2x2: Downscales each 2x2 block of pixels to an average. This is intended to write to a render target that is half the size of the source texture in each dimension.
• DownScale_4x4: Downscales each 4x4 block of pixels to an average. This is intended to write to a render target that is a quarter the size of the source texture in each dimension.
• GaussianBlur_5x5: Performs a Gaussian blur with a 5x5 kernel
• BloomExtract: Performs a bloom extract, which is the first pass in implementing a bloom effect
• BloomBlur: Performs a horizontal or vertical blur which is typically the second and third passes of implementing a bloom effect.

Properties

• SetSourceTexture is used to set the input texture as a Shader Resource View.

• SetGaussianParameter sets the multiplier for the GaussianBlur_5x5 shader.

• SetBloomExtractParameter sets the extract parameter for the BloomExtract shader.

• SetBloomBlurParameters sets the horizontal vs. vertical mode as well as the size and brightness factors for the BloomBlur shader.
