There are various techniques to integrate projector calibrations into the displaying system. We call this feature hooking. There are different ways to embed the calibrations into the operating system:
- Hardware-based hooking. On this level the warping and blending data is imported directly into graphics processing unit (GPU). This hooking mode requires to use professional series of graphics cards.
- NVIDIA NVAPI: available on NVIDIA Quadro GPU K5200 or better
- AMD D.O.P.P: available on AMD FirePro w600 (other models are unreliable in D.O.P.P. support)
- Desktop hooking (DWM): This embedding mode applies the calibration data onto Windows display configuration. For this mode it is required to have Windows 7 (not 8.1 and 10!) as operation system with Aero Theme activated.
- API Hooking: Contents are altered at runtime when certain 3D APIs are used. Provided by Anyblend on demand. Currenty supported 3D APIs are:
- DirectX 9
- Application hooking: Warp&Blend files are processed by the image generating application. Provided as a plugin or calibration file loader by VIOSO or the vendor of the application. Note that this might involve extra coasts for development time. For a list of supported applications click here.
