np.asarray(pcd.colors)[idx[1:], :] = [0, 0, 1] 函数search_knn_vector_3d返回锚点的k个最近邻居的索引列表。 这些相邻点涂有蓝色。 请注意,我们将pcd.colors转换为numpy数组以批量访问点颜色,并向所有选定点广播蓝色[0,0,1]。 我们跳过第一个索引,因为它是锚点本身。 使用search_radius_vector_3d ...

我的最终目的是将经过纹理处理的obj模型作为单个TriangleMesh对象加载到三网格中,或者将纹理转换为彩色点云,以便只使用存储在vertex_colors属性中的颜色。当我使用trimesh.load时,它会返回一个具有多重几何学的场景。当我打trimesh.load(force='mesh')电话时,所有的纹理都搞砸了。我还尝试用open3d加载obj文件,然后...
