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,...
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...
“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...
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...
Rotate means to circle around a center point. Wheels on a car rotate, planets rotate, and if you're an ice skater, you rotate on the blade of a skate when you do your spins.Rotate can also mean that you take turns performing a job. If you, Jim, and Shelia all got the same ...

How do I add my operator's Access Point Name to my phone? Settings and others Edge Sense is sometimes triggered when my phone is in a car kit or selfie stick. What should I do? Can I cut my micro SIM to a nano SIM so it can fit in my HTC device? How do I find the ...
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,...

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 ...
