Concave Hull earns a spot in the superhive library for turning point clouds into meshes through a single operator, with threshold control over the reconstruction and quick handling of large datasets.
Concave Hull (Points To Surface Mesh) is a Blender add-on from CGMatter that reconstructs the surface of any point cloud, working as a point-to-mesh operator. The developer notes this operation matters in photogrammetry, data interpolation, and general modeling. It also calculates quickly with large datasets.
The add-on exposes a small set of controls. A Threshold float sets the minimum threshold for geometry to be created, while Grid Spacing defines the distance between sample voxels. A Connections integer densifies the point cloud, and a Show Connected toggle displays that densification. The threshold parameter is what controls the surface reconstruction.
Concave Hull installs like any other Blender add-on: drag the .zip into Blender 4.3 or newer and confirm. It is listed as Blender Extension compatible, works with the Cycles and Eevee render engines, and is released under the GPL license. The add-on is also bundled with CGMatter's Genie, and a demo video and documentation are available.
Concave Hull (Points To Surface Mesh) is best for photogrammetry, data interpolation, and general modeling where a point cloud needs to become a surface mesh.
Concave Hull (Points To Surface Mesh) is completely free to download and use.
Concave Hull is installed by dragging its .zip file into Blender 4.3 or newer and confirming, so that version marks the supported baseline. The listing also records a Blender version of 5.1 and notes the add-on is Blender Extension compatible. It works with both the Cycles and Eevee render engines. For the exact version behaviour on your setup, check the developer's page before installing.
Concave Hull installs the same way as any other Blender add-on. Drag the .zip file directly into Blender 4.3 or newer and click confirm, and that completes the setup. The add-on is listed as Blender Extension compatible, and documentation is available if you need a reference while getting started. It is also bundled with CGMatter's Genie, so owners of that tool have access to the same operator.
Concave Hull provides four parameters. Threshold, a float, sets the minimum threshold for geometry to be created and is what controls the surface reconstruction. Grid Spacing, a float, defines the distance between sample voxels. Connections, an integer, densifies the point cloud, and Show Connected, a boolean, displays that densification. Together these let you adjust how the point cloud is reconstructed into a mesh.
Concave Hull is listed as free in this catalog, and it is released under the GPL license. Pricing and bundling can change over time, and the add-on is also offered alongside CGMatter's Genie, so check the developer's page for current licensing and availability details before you download. A demo video and documentation are also available there to help you decide whether it fits your project.
