易语言源码OPENGL应用中纹理贴图的方法.rar
首先要导入Open3d包:
```python
import open3d as o3d
```
接着,读入网格和纹理图片:
```python
mesh = o3d.io.read_triangle_mesh("mesh.obj")
texture = o3d.io.read_image("texture.jpg")
```
然后,将纹理图片映射到网格上:
```python
mesh.compute_vertex_normals()
mesh.compute_triangle_normals()
mesh.paint_uniform_color([0.7, 0.7, 0.7])
mesh.compute_vertex_normals()
mesh.compute_triangle_normals()
mesh.texcoords = o3d.utility.Vector2dVector([[0, 0], [1, 0], [1, 1], [0, 1]])
mesh.triangle_uvs = o3d.utility.Vector2iVector([[0, 1, 2], [0, 2, 3]])
mesh.textures = [texture]
o3d.visualization.draw_geometries([mesh])
```
最后,展示贴上纹理的网格:
```python
o3d.visualization.draw_geometries([mesh])
```
