In this study,we propose a novel method to reconstruct the 3D shapes of transparent objects using images captured by handheld cameras under natural lighting conditions.It combines the advantages of an explicit mesh an...
Climate change is a global issue faced by humanity.With the drastic increase in carbon dioxide(CO_(2))emissions worldwide,greenhouse gases are accumulating at a horrendous rate,exposing the ecosystem to serious threat...

Gradient-domain rendering methods can render higher-quality images at the same time cost compared with traditional ray tracing rendering methods, and, combined with the neural network, achieve better rendering quality...
Three-dimensional surfaces are typically modeled as implicit surfaces.However,direct rendering of implicit surfaces is not simple,especially when such surfaces contain finely detailed shapes.One approach is ray-castin...
