可见,一个坐标系的根本用途,即让我们在处理不同的问题时,能够以合适的参照系,抛开不相关的因素,从而减小问题的复杂度。 直观地讲,模型顶点中的纹理坐标,就定义于切线空间。普通2维纹理坐标包含U、V两项,其中U坐标增长的方向, 即切线空间中的tangent轴,V坐标增加的方向,为切线空间中的bitangent轴。模型中不同的...

There are many reasons why having a bestie is super awesome and important. Being alive is hard y’all. There’s responsibilities and expectations and requirements. And that’s all a bit overwhelming. Also – even if we travel through this space we call life with people who are close to us...
Most of the time these plasmas can be regarded as microplasmas both from the point of view of space and time, since they are confined to a tiny region of the space and last for just a fraction of a second. An intensive generation of such microplasmas may have important implications for ...

1, o–xyz is the camera coordinate system, π1 is the space plane, and π2 is the image plane. When the circle on π1 is projected to π2, the image is an ellipse. AB is the diameter of the circle, and Aʹ and Bʹ are the images of point A and point B, respectively. ...
TANGENT_SPACE_ROTATION 宏 相当于嵌入如下两行代码: float3 binormal = cross( v.normal, v.tangent.xyz ) * v.tangent.w; float3x3 rotation = float3x3( v.tangent.xyz, binormal, v.normal ); 也就是构造出 tangent space 的坐标系, 定义转换world space的向量到tangent space的rotation 矩阵。
Let X be a metric space equipped with a doubling measure which satisfies the (1, p)-Poincaré inequality. Consider the following metric analogue of the left-hand side of the equality in Theorem 1.1: We will call Q_{r,p} the BBM difference quotient. It corresponds to taking the mollifier...
NASAuses sine, cosine, and tangent. Its physicists and astronauts often use robotic arms to complete assignments in space and use trigonometry to determine where and how to move the arm to complete their task. Thinking about studying marine biology? In this career, sine, cosine, and tangent ar...
