OpenGL tessellation: equation for coordinates of new triangles inside original triangle

Dear AMD developers,

 

are you allowed to share the equation which computes the uvw coordinates of a tessellation-result-triangle of the outer triangle coordinates? I am implementing OpenGL's inner tessellation in C++ on CPU to emulate GPU tessellation because I need to process the result on CPU not as an image on GPU. For that I would like to compare my point finding with the original equation.

 

Thank you and with best regards,

Stephan
