WebPipeline. Our key idea in HumanGen is to organically leverage a 2D human generator and a 3D human reconstructor as explicit priors into a 3D GAN-like framework. HumanGen consists of three modules. The hybrid feature module includes anchor image and tri-plane feature generation. The geometry module includes reconstruction prior and SDF adaptation.

WebDiscretizing \(\frac{\partial ^2 u}{\partial x^2}\) ¶. The second-order derivative can be represented geometrically as the line tangent to the curve given by the first derivative. We will discretize the second-order derivative with a Central Difference scheme: a combination of Forward Difference and Backward Difference of the first derivative. WebImplicit schemes are unconditionally stable (though in practice you still need a reasonable time step for accurary) Typically problems where inertial effects are important (e.g., wave propagation) are solved by explicit schemes where as quasi-static problems usually use an implicit scheme. However there are exceptions.
