vector quantity

The best scheme was chosen after analysis and comparing and the structure was designed . at same time , the kinematics analysis was conducted , coordinate transformation matrix using d - h method was set up , and the kinematics equation direct solution and inverse solution was deduced , the velocity jacobian matrix was constructed using vector product method , and the values of displacement and velocity of some special point including the wrist point were calculated . secondly , the working space of the robot was analyzed and the axes section of practical working space was drawn 首先,作者針對機器人的設計要求提出了多個方案,對其進行分析比較,選擇其中最優的方案進行了結構設計;同時進行了運動學分析,用d - h方法建立了坐標變換矩陣,推算了運動方程的正、逆解;用矢量積法推導了速度雅可比矩陣,并計算了包括腕點在內的一些點的位移和速度;然后借助坐標變換矩陣進行工作空間分析,作出了實際工作空間的軸剖面。

The implementation in this paper packs 4 cons 4 * 1 consecutive elements from a matrix column into a texel and thus performs a small number of 4 * 4 matrix by 4 * 1 vector products in a shader 每次從矩陣中取出4個元素放入一個到文理單元的一個元素中, 4 4的小規模矩陣乘法就轉變成了4 1的向量乘法。

The vector product node named matrixmult uses a point matrix product operation to multiply those coordinates by the worldinversematrix of the sphere ' s shape node 那是,在球中心的一個點需要去返回一個0 , 0 , 0的數值,不管球在空間的哪個地方。

Instead , a custom facing ratio is computed using a vector product utility node in the shading network 相反地,一個特定的分形比率是在材質網絡里使用一個積向量功能節點來計算的。
