下面结合Transform,具体说说两种语义在具体问题中的应用。 Transform本身即状态量,表示Child空间的坐标系在Parent空间中的表达,其中包含Rotation分量和Translation分量,所以Transform可以看作是Parent空间中的物体。 本文上一节分别对Transform左乘和右乘同一个旋转矩阵(绕x轴旋转-90度)。 左乘的结果:Child空间的坐标系量系...
图中的Rotation和Translation两步就是相机定位时所发生的变换。可以看到相机相对于小人的运动。而当进行相机变换的时候,小人应该从世界基变换到相机的基里面。这样,他应该进行一个相机定位的逆定位,先逆平移小人和相机,然后再逆旋转小人和相机,最后相机归位,小人随相机变到了相机空间。这是由Inverse Translation和Inverse...

1.Every matrix M is associated with a coordinate system. This coordinate system has origin (t0,t1,t2) and vectors (a00,a110,a20), (a01,a11,a21), and (a02,a12,a22) as axes. Matrix M maps the standard coordinate system to the coordinate system with the origin (0, 0, 0) and axes ...
The final appearance of your scene or object can depend greatly on the order in which the modeling transformations are applied(你渲染物体的最终结果取决于这些变换矩阵的相乘的顺序). This is particularly true of translation and rotation. We can see this as a consequence of the associativity and com...
Specifically, we investigate the relative contributions of the data cache, the translation lookaside buffer, register tiling, and the array layout function to the overall running time of the algorithms. We use various memory models to capture and analyze the effect of various facets of cache memory...
