Please help me how to construct circle in the plane with a point by center and radius; circle with a point by center and point in this circle.
Thanks!

I can't edit radio like you and your test isn't true of me to ask.
I need circle  with center and  the measure given radius.

Thanks!

Oh no! I want locus of graph rotate around Ox axis or Oy axis. You maked the circle trace of graph.
Please see my GSP file.

Point on circle maked locus but when point move on circle then trace of locus and locus don't move with it. Why? Can locus move in InRm3D ?

namtran 发表于 2009-7-23 15:30
从附件中看这里有几个问题:
1、由输入方程构造的曲线不能保留痕迹,因此想构造一条圆上的点的轨迹来替代。但是圆上的点也是动点,这样轨迹线不能跟着该点动;
2、多点驱动轨迹这是目前所有画板中的难题。
要是应该是这样的效果:

“多点驱动轨迹”是什么意思?

“多点驱动轨迹”是什么意思?
inRm 发表于 2009-7-25 12:48
即多个约束点带动一个轨迹点的轨迹,实际上本问题即为一例。包括弹簧的构造。实际上就是轨迹法构造空间曲线。
