drawLines() bool GiGraphics::drawLines ( const GiContext *  ctx, int  count, const Point2d *  points, bool  modelUnit = true  ) 绘制折线，模型坐标或世界坐标 参数 ctx 绘图参数，忽略填充参数，为NULL时取为上一个绘图参数 count 点的个数，至少为2 points 顶点数组，点数为count modelUnit 指定的坐标尺寸是模型坐标(true)还是世界坐标(false) 返回 是否显示成功。失败原因为参数错误或超出剪裁区域 函数调用图: 这是这个函数的调用关系图:
