WebThe following tutorial provides a method to compute the T and B vectors from N: Tangent Space Computing. I think that the essence of the theoretical implementation of the bump mapping is clarified. It is time to go inside the GLSL code for really understanding some-thing there... fig.3 - The normal-map in the tangent space. WebNote that getting an understanding of normal mapping, specifically tangent space, is strongly advised before learning parallax mapping. Parallax mapping is closely related to the family of displacement mapping techniques that displace or offset vertices based on geometrical information stored inside a texture.

WebAs stated, I need to transform fragment-to-camera to tangent space and then pass it to a function. tangent space is computed using Assimp. Well I trusted it. For example tangent vectors look like that (Sponza model): then in vertex I make transformation as in tutorial: http://www.opengl-tutorial.org/intermediate-tutorials/tutorial-13-normal-mapping/ intoxicated interpretation wsj https://mcneilllehman.com
