Point Cloud Viewer and Tools v2.70
“If possible, please buy the package to support the developer”
Main features:
– DX11 Point Cloud Viewer (up to 40 million points using single color *could depend on your hardware stats)
– Single color and RGB point cloud shaders included (for both DX11 & non-dx11 modes)
– Supported import formats: XYZ, XYZRGB, CGO, ASC, CATIA ASC, PLY (ASC)
– Editor plugin#1: Point Cloud To Binary (saves data to custom binary format for faster reading)
– Editor plugin#2: Point Cloud To Unity Meshes (splits point cloud data into 65k meshes)
– Brekel Point Cloud Pro v2 binary file support (view & convert animated point clouds)
* Check pdf below for more details!
Main limitations:
– Main viewer requires DX11 (does not work on Apple Macs)
– Can only display 1 cloud at a time (so you must combine clouds and filter them to have suitable data)
– If you use RGB colors, maximum is ~20million (instead of 40mil) *New: With Unity 5.1 tested loading 75million points (single color) ~10fps in editor..
– Current version loads the points at Start() function, you need to modify the viewer script if you want it to load them some other time
– There is no any “API”, just few normal unity c# scripts & shaders to display the points
– Not much error checking is done on imported files, if they are different from supported file formats, most likely it breaks

PointCloudViewerTools_web13.pdf *old version
Roadmap/future plans:
– Support for float RGB values (currently it expects int values 0-255)
– DX11 point size (if its possible to make it work)
– New import formats
– Add touch screen flying controls for the mobile demo
– Include webplayer compatible reader (instead of using System.IO) : (*In v1.3)
– Support for point normals (*New v1.3 import normals for PLY (ascii), only for cloud2mesh, not in DX11)
– .LAS file format support (import) (*in v1.8)
– .PTS file format support (import) (*in v1.8)
– more.. (feel free to comment/request)
Wishlist / Requests:
– DX11 Point Size
– .E57 file format support
– Support for point normals dx11 (need to somehow pack the normals into position or color values..)
– Support for .abc / .fbx / .obj formats
– Shaders for points + unity lights (pretty much needs normals, unless make it just distance based brightness)
– Clipping boxes / planes
– Taking measures *available as customized work (but starts to get slow with over 5-10mil. points)
– LOD (based on camera distance and/or octree lods)
– Compressed or less precision binary format (smaller files)
– Oculus version of the pc demo scene
Bugs:
– (14.4.2014): Mesh Converter: If point amount is less than “Vertices per mesh” amount, cloud meshes are not generated. This will be fixed in next update (or email me for manual fix) **Fix submitted to asset store 27.4.2014)
Demos:
PC exe 2.5million points (dx11) : mediafire | dropbox
Android (.apk) 2.5 million points (non-dx11) : mediafire | dropbox (*60fps in Samsung Galaxy S4)
iPhone5 : Doesnt seem to work properly, hangs, point sizes are wrong etc.. will test again with unity4.6 or 5..
