Splet01. dec. 2024 · A tensor can be represented by a rank- and shape- pair, where the rank indicates the number of dimensions the tensor has, and the shape indicates the number of elements in each dimension. The rank- and shape-pairs are stored in a two-dimensional array. To manipulate Tensors in Python we use the NumPy library. Splet23. jan. 2024 · Inertia tensor is normally defined as a 3x3 Matrix Unity and Physx give something equivalent, an IntertiaTensor, and an InertiaTensorRotation. I think they do it like this because it is cheaper (3+4 = 7 values) against (3x3=9 values). My question is, having an InertiaTensor and an InertiaTensorRotation, how can I calculate the 3x3 Inertia Tensor? gifted lyrics jay critch https://theeowencook.com
