Gradiant of sdf field
Web2 days ago · Solutions to the Vanishing Gradient Problem. An easy solution to avoid the vanishing gradient problem is by selecting the activation function wisely, taking into account factors such as the number of layers in the neural network. Prefer using activation functions like ReLU, ELU, etc. Use LSTM models (Long Short-Term Memory). Webthe divergence of the gradient of the field means that any point on the surface being a sink will return negative "curvature" and vice-versa (since the gradient of a SDF should point to the centroid at any point in space). So now, I include the 7-tap version which is a more accurate Laplacian,
