Non-linear sphere tracing for rendering deformed signed distance fieldscs.dartmouth.edu/~wjarosz/publications/seyb19nonlinear.html 论文里的方法很有意思:瑕疵的根源在于,一个 SDF 经过某个函数进行了形变(比如我上次用 SH 对一个球面进行扭曲)导致我们无法得到正确扭曲后的 distance。我们可以反过来思考,如果...

Similarly, the non-linear σ models we consider here are based harmonic maps from the Riemann sphere to complex projective m space. In seminal work, Segal [35] studied ℛ( m ) k , the space of based rational maps from the Riemann sphere to complex projective m space of a fixed degree...
A non-linear heterogeneous half-space is considered as being defined by one modulus and two exponents to describe the increase of stiffness with depth and the degree of nonlinearity. This 'parabolic' half-space contains the linear elastic models of Boussinesq, Gibson and Booker et al. as subsets...
Topological band theory establishes a standardized framework for classifying different types of topological matters. Recent investigations have shown that hyperbolic lattices in non-Euclidean space can also be characterized by hyperbolic Bloch theorem. T
PHASE-SPACE LINEARIZATION FOR NON-LINEAR OSCILLATORS: DETERMINISTIC AND STOCHASTIC SYSTEMS A new and efficient semi-analytical phase-space linearization (PSL) scheme for a class of non-linear oscillators is developed in this paper. The method is ... D Roy - 《Journal of Sound & Vibration》 被...

Start by creating a linear space: Python >>> import numpy as np >>> x_ = np.linspace(1, 10, 10) >>> x_ array([ 1., 2., 3., 4., 5., 6., 7., 8., 9., 10.]) You can now transform this to be a range of numbers that are linear over x2: Python >>> x_ ...
We relate some classical extremal problems on the Hardy space to norms of truncated Toeplitz operators and complex symmetric operators.
