Using the C++/shader source for setting up ACES tone mapper shader constants as well as the shader sources provided by NVIDIA Developer Technology, it was easy to add support for a range of ACES tone mapping curves to the game (see Figure 1). All that needed to be done was to utilize the available C++ classes to setup constant buffer data that was then fed into the provided ACES tone mapping shader........"
