http://stackoverflow.com/questions/2259476/rotating-a-point-about-another-point-2d 如果你也是使用Unity做为开发引擎,可以参考如下代码:如下代码是考虑基于Y轴旋转的,所以你可以将点(x,z)看做平面内的一个支点,angle表示要基于(x,z)点旋转的角度,point是要旋转的点,具体代码如下: Vector3RotatePoint(floatx,...
“Rotate” is a verb that means to turn in a circular motion around a center point. rotate是一个动词,意思是绕着一个中心点做圆周运动。 The verb can take a direct object or not. 它可以带直接宾语,也可以不带。 The earth rotates around the sun. (no direct object) 地球绕着太阳转。(没有...
2. to proceed in a fixed routine of succession. v.t. 3. to cause to turn around an axis or center point. 4. to cause to go through a cycle of changes or follow in a fixed routine of succession: to rotate crops. 5. to replace (a person, troops, etc.) by another or other...
Rotate also has another meaning. “Rotate” can mean to take turns or to pass or change something in a series. We should rotate our car’stiresevery 5,000 to 7,000 miles. Now let’s look at “spin.” The verb “spin” also means to turn in a circular motion on a center point,...
Create a quaternion vector specifying two separate rotations, one to rotate the point 45 and another to rotate the point -90 degrees about the z-axis. Use rotatepoint to perform the rotation. Get quat = quaternion([0,0,pi/4; ... 0,0,-pi/2],"euler","XYZ","point"); rotatedPoin...
to cause to turn around an axis or center point; revolve. Synonyms:whirl,wheel to cause to go through a cycle of changes; cause to pass or follow in a fixed routine of succession: to rotate farm crops. to replace (a person, troops, etc.) by another or others, usually according to ...
Now rotate the surface about the y-axis that passes through the point x = 20. Create two translation matrices, one to translate the surface -20 units in x and another to translate 20 units back. Concatenate the two translation matrices with the rotation matrix in the correct order and set...

The orthopedic device includes a foot support element configured to substantially support a user's foot or ankle, the foot support element having a first portion and a second portion that are configured to rotate with respect to one another about a pivot point. The orthopedic device further ...
Let's start with "rotate.""Rotate" is a verb that means to turn in a circular motion around a center point. 我们先看rotate。rotate是一个动词,意思是绕着一个中心点做圆周运动。 The verb can take a direct object or not. 它可以带直接宾语,也可以不带。
