一、绘制一个三维的爱心
关于这一步,我采用的是大佬博客中的最后一种绘制方法。当然,根据我的代码习惯,我还是稍做了一点点修改的。- class Guess:
- def __init__(self, bbox=(-1.5, 1.5), resolution=50, lines=20) -> None:
- """
- bbox: 控制画格的大小
- resolution: 控制爱心的分辨率
- lines: 控制等高线的数量
- """
- self.xmin, self.xmax, self.ymin, self.ymax, self.zmin, self.zmax = bbox*3
- A = np.linspace(self.xmin, self.xmax, resolution)
- self.B = np.linspace(self.xmin, self.xmax, lines)
- self.A1, self.A2 = np.meshgrid(A, A)
-
- def coordinate(self, x, y, z):
- """
- 生成坐标
- """
- return (x**2+(9/4)*y**2+z**2-1)**3-x**2*z**3-(9/80)*y**2*z**3
- def draw(self, ax):
- """
- 绘制坐标
- """
- for z in self.B:
- X, Y = self.A1, self.A2
- Z = self.coordinate(X, Y, z)+z
- cset = ax.contour(X, Y, Z, [z], zdir='z', colors=('pink',))
- for y in self.B:
- X, Z = self.A1, self.A2
- Y = self.coordinate(X, y, Z)+y
- cset = ax.contour(X, Y, Z, [y], zdir='y', colors=('pink',))
- for x in self.B:
- Y, Z = self.A1, self.A2
- X = self.coordinate(x, Y, Z) + x
- cset = ax.contour(X, Y, Z, [x], zdir='x', colors=('pink',))
- def run(self):
- fig = plt.figure()
- ax = fig.add_subplot(projection='3d')
- ax.set_zlim3d(self.zmin, self.zmax)
- ax.set_xlim3d(self.xmin, self.xmax)
- ax.set_ylim3d(self.ymin, self.ymax)
- plt.show()
复制代码 但是这可以达到我们想要的效果吗?
显然不能!于是我们开始加入亿点点细节!
二、细节点
1.加入时间序列
想要心脏跳起来,我们就需要有时间维度的变化。那怎么做最合理呢?这里仅展示修改的代码位置。
代码如下(示例):- class Guess:
- def __init__(self, bbox=(-1.5, 1.5), resolution=50, lines=20) -> None:
- plt.ion() # 开启画布的动态图模式
- self.xmin, self.xmax, self.ymin, self.ymax, self.zmin, self.zmax = bbox*3
- self.time = time.time() # 这里有一个衡量的时间坐标,很合理吧
- A = np.linspace(self.xmin, self.xmax, resolution)
- self.B = np.linspace(self.xmin, self.xmax, lines)
- self.A1, self.A2 = np.meshgrid(A, A)
- def run(self, count):
- """
- 加入count是我们想循环的次数
- """
- fig = plt.figure()
- for i in range(count):
- plt.clf() # 每次清除画布
- ax = fig.add_subplot(projection='3d')
- ax.set_zlim3d(self.zmin, self.zmax)
- ax.set_xlim3d(self.xmin, self.xmax)
- ax.set_ylim3d(self.ymin, self.ymax)
- times = time.time()-self.t/ime # 计算画布的当前时间状态
- self.draw(ax, coef)
- plt.show()
复制代码
2.加入心脏的跳动
心脏的跳动当然不会是线性的了,我们需要心脏的跳动是有层次感的,并且还是可以做往返运动的。
emmmmm… 这么说来,cos是不是就是做这个用的?
于是…
代码如下(示例):- def __init__(self, bbox=(-1.5, 1.5), resolution=50, lines=20, scale=1.2) ->
- None:
- """
- scale: 心脏缩放的系数
- """
- self.xmin, self.xmax, self.ymin, self.ymax, self.zmin, self.zmax = bbox*3
- plt.ion()
- self.scale = scale # scale: 心脏缩放的系数 设置为全局变量
- self.time = time.time()
- A = np.linspace(self.xmin, self.xmax, resolution)
- self.B = np.linspace(self.xmin, self.xmax, lines)
- self.A1, self.A2 = np.meshgrid(A, A)
- def draw(self, ax, coef):
- """
- coef: 使得心脏可以按照时间跳动
- """
- for z in self.B:
- X, Y = self.A1, self.A2
- Z = self.coordinate(X, Y, z)+z
- cset = ax.contour(X * coef, Y * coef, Z * coef, [z * coef], zdir='z', colors=('pink',))
- for y in self.B:
- X, Z = self.A1, self.A2
- Y = self.coordinate(X, y, Z)+y
- cset = ax.contour(X * coef, Y * coef, Z * coef, [y * coef], zdir='y', colors=('pink',))
- for x in self.B:
- Y, Z = self.A1, self.A2
- X = self.coordinate(x, Y, Z) + x
- cset = ax.contour(X * coef, Y * coef, Z * coef, [x * coef], zdir='x', colors=('pink',))
- def run(self, count):
- """
- 加入count是我们想循环的次数
- """
- fig = plt.figure()
- for i in range(count):
- plt.clf() # 每次清除画布
- ax = fig.add_subplot(projection='3d')
- ax.set_zlim3d(self.zmin, self.zmax)
- ax.set_xlim3d(self.xmin, self.xmax)
- ax.set_ylim3d(self.ymin, self.ymax)
- times = time.time()-self.time
- coef = np.cos(times) * (self.scale-1) + 1
- # coef 是用来放缩心脏的大小的,加入cos来使它有节奏的跳动
- self.draw(ax, coef)
- plt.pause(0.01)
- plt.show()
复制代码 很好,这样我们就有了一个可以跳动的心脏,那么到这结束了嘛?
一个好的展示
当然没有!我们希望对象看到的时候他稍微有点东西,所以让它跳动却不能改变方向,岂不是看的不够全面?所以我们在加最后亿点点细节:
- def run(self, count):
- fig = plt.figure()
- for i in range(count):
- plt.clf()
- ax = fig.add_subplot(projection='3d')
- ax.set_title("你对象的名字?") # 加上你对象的小name
- ax.set_zlim3d(self.zmin, self.zmax)
- ax.set_xlim3d(self.xmin, self.xmax)
- ax.set_ylim3d(self.ymin, self.ymax)
- times = time.time()-self.time
- ax.view_init(10, 100+np.cos(times) * 10) # 让三维坐标图可以变换坐标展示
- coef = np.cos(times) * (self.scale-1) + 1
- self.draw(ax, coef)
- plt.pause(0.01) # 让绘制出来的心脏可以显示
- plt.show()
