以矩阵形状单位实例化预制结构

class Instance:
    def __init__(self, model):
        self.model = model

    def destroy(self):
        # 释放模型资源
        self.model.release()

# 示例代码
instances = []
for i in range(1000):
    instance = Instance(load_model())
    instances.append(instance)

# 销毁实例
for instance in instances:
    instance.destroy()

import numpy as np

# 示例代码
def create_matrix(position, rotation, scale):
    translation_matrix = np.array([
        [1, 0, 0, position[0]],
        [0, 1, 0, position[1]],
        [0, 0, 1, position[2]],
        [0, 0, 0, 1]
    ])
    rotation_matrix = np.array([
        [np.cos(rotation[0]), -np.sin(rotation[0]), 0, 0],
        [np.sin(rotation[0]), np.cos(rotation[0]), 0, 0],
        [0, 0, 1, 0],

        [0, 0, 0, 1]
    ])
    return translation_matrix @ rotation_matrix @ scale_matrix

# 使用示例
matrix = create_matrix([1, 2, 3], [np.pi/4, 0, 0], [2, 2, 2])
