好的,我会尝试回答你的问题。首先需要说明的是,作为一个AI模型,我并不具备直接绘制图形的能力。不过,我可以告诉你如何使用Python中的Matplotlib库读取并绘制图形,希望能对你有所帮助。
以下是具体的步骤:
1. 导入所需的库
```python
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
from matplotlib.collections import LineCollection
```
2. 读取恐龙图形的点坐标文件
```python
data = pd.read_csv('dinosaur.csv', header=None)
```
3. 绘制原恐龙
```python
fig, ax = plt.subplots()
ax.set_aspect('equal')
ax.autoscale_view()
segments = np.split(data.values, np.where(np.isnan(data.values[:, 0]))[0][1:-1]+1)
lc = LineCollection(segments, colors='black', linewidths=0.5)
ax.add_collection(lc)
plt.show()
```
4. 旋转30度角,再绘制新恐龙
```python
fig, ax = plt.subplots()
ax.set_aspect('equal')
ax.autoscale_view()
theta = np.radians(30)
c, s = np.cos(theta), np.sin(theta)
rotation_matrix = np.array(((c, -s), (s, c)))
rotated_data = []
for segment in segments:
rotated_segment = np.dot(segment[:,:2], rotation_matrix)
rotated_segment = np.hstack((rotated_segment, np.nan*np.ones((len(rotated_segment),1))))
rotated_data.append(rotated_segment)
lc = LineCollection(rotated_data, colors='black', linewidths=0.5)
ax.add_collection(lc)
plt.show()
```
5. 旋转60度角,再绘制新恐龙
```python
fig, ax = plt.subplots()
ax.set_aspect('equal')
ax.autoscale_view()
theta = np.radians(60)
c, s = np.cos(theta), np.sin(theta)
rotation_matrix = np.array(((c, -s), (s, c)))
rotated_data = []
for segment in segments:
rotated_segment = np.dot(segment[:,:2], rotation_matrix)
rotated_segment = np.hstack((rotated_segment, np.nan*np.ones((len(rotated_segment),1))))
rotated_data.append(rotated_segment)
lc = LineCollection(rotated_data, colors='black', linewidths=0.5)
ax.add_collection(lc)
plt.show()
```
希望这些代码能帮助你完成绘制恐龙图形的任务。如果你有任何问题或需要更多帮助,请随时告诉我。
