The unprecedented advancements in Large Language Models (LLMs) have created a profound impact on natural language processing but are yet to fully embrace the realm of 3D understanding. This paper introduces PointLLM, a preliminary effort to fill this gap, thereby enabling LLMs to understand point...

Point clouds are most often created by 3D scanners These devices measure in an automatic way a large number of points on the surface of an object, and often output a point cloud as a data file The point cloud represents the set of points that the device 3、has measured.As the result ...

Point cloud: A point cloud is essentially a large collection of tiny points drawn in 3D space, as shown inFig. 1(a), which consists of a large collection of points captured using a 3D laser scanner. These points can express the spatial distribution and surface characteristics of the target...
In point cloud compression, sufficient contexts are significant for modeling the point cloud distribution. However, the contexts gathered by the previous voxel-based methods decrease when handling sparse point clouds. To address this problem, we propose a multiple-contexts deep learning framework called...
A voxel 3D model, the result of the current open-source python tutorial. It is automatically extracted from a large point cloud accessible in the article. © F. Poux What if we had a quick way to transform point clouds captured from reality into 3D meshes? And what if these 3D ...
Efficient Hierarchical Entropy Model(EHEM) 整体Pipeline EHEM将上下文窗口内的子序列分为两组,第一组只依赖于祖先节点,第二组同时依赖于祖先节点和第一组节点(兄弟节点),以此减少计算复杂度。 编码时所有节点已知,可以直接用来估计概率,解码时祖先节点已知,可以用来计算第一组节点,并将第一组节点(图中的1,3)连...
