存在一个视点(相机),一个投影平面,和需要被投影至面上的点;另外,我们习惯于将视点置于经典笛卡尔坐标系的原点O。 投影几何点 Points in Projective Geometry 与齐次坐标 Homogeneous Coordinates 齐次坐标 三维空间中点的坐标通常用(x,y,z)表示;而齐次坐标便是在当前维度的坐标表示下,为其扩展一个分量w,使其变为...
Homogeneous coordinates and projective geometry bear exactly the same relationship. Homogeneous co-ordinates provide a method for doing calculations and proving theorems in projective geometry, especially when it is used in practical applications. Although projective geometry is a perfectly good area of "...

Transformations is a Python library for calculating 4x4 matrices for translating, rotating, reflecting, scaling, shearing, projecting, orthogonalizing, and superimposing arrays of 3D homogeneous coordinates as well as for converting between rotation matrices, Euler angles, and quaternions. Also includes an...

Heat flow is an inhomogeneous, nonlinear function of particle velocities and coordinates. Thus, Gauss' principle cannot be relied upon for treating inhomogeneous nonlinear nonholonomic constraints. 展开 关键词: Nonequilibrium molecular dynamics conductivity heat flow irreversible thermodynamics steady state ...
It is assumed that in the first step in neutral medium [RuIIRuIII(µ-CO3)4(OH)]4− undergoes one electron oxidation and simultaneously coordinates one OH− to the open axial position of the other RuIII ion to form [RuIIIRuIII(µ-CO3)4(OH)2]4−, (Equation (21)). [RuIIRu...
