Display, edit, filter, render, convert, generate and export colored point cloud PLY files.
Works with any Binary or ASCII PLY file with ‘x, y, z, nx, ny, nz, red, green, blue’ vertex values. Vertex normals and colors are optional.

Shader type and its options (if any). Also display extras - point
Bounding Box, extras options are shown with icon on side.
Here are options for ply loading, loaded data post-processing and safety checks.
To use partial load, first enable clicking checkbox
Partial Load and set method. For extra large clouds with ordered data, you can choose
Slice method which will load only a continuous part of points. To extract points from whole file you can use
Spaced first load all points to system memory and then evenly spaced points from all are chosen and the rest is discarded to free system memory. This can be used when you are able to fit all points into system memory, but you don’t need to draw them all and it is still quite fast.
Random method is slow, but much less system memory is needed to load subset of points. Points are read from file randomly and only single point is read each time until requested percentage is met.
Data post-processing lets you choose default color if points does not have any, convert 16bit colors, apply gamma correction, shuffle points (to be used with
Shader > Display), you can disable storing of raw loaded data to save memory or disable automatic drawing after load to check number of loaded points first before drawing to prevent crashes from low gpu memory.
Safety lets you set maximum number of points to display regardless how many points are loaded to prevent crashes from low gpu memory.
To use, switch shader type to
Clip. This shader is drawn with 6 clipping planes. Planes can be enabled/disabled independently with eye icon, first 3 values are plane normal (x, y, z), last value is plane distance from origin. These can be set from different object bounding box, choose object from scene in
Object and hit
Set Clip Planes From Object Bounding Box, object can then be hidden/deleted, set values will stay until operator is executed again.
X reset all the settings to their defaults.
Quasi point cloud Edit Mode. Hit
Enable Edit Mode and all points will be converted to helper mesh with vertices and entered to mesh edit mode. You can transform, delete and duplicate vertices using regular Blender’s tools.
Filter current point cloud, all changes are only temporary, original data are still intact. To keep changes, you have to export cloud as ply file.
Simplify point cloud to exact number of evenly distributed samples or voxel-like structure.
Project points on mesh (or object convertible to mesh) surface. Projects point along their normals until it hit surface or
Search Distance is reached. You can choose between
Positive (along normal direction),
Negative (vice versa) or both. Optionally you can
Discard Unprojectable points that was not possible to project and after projection
Shift points a fixed distance along normal (positive value) or the other way around (negative value). Projected points can be optionally colorized by vertex colors, uv texture and vertex group from target mesh.
Transfer colors from point to
Target mesh object vertex colors or UV texture. By default, color is taken from closest point, optionally you average point colors in set radius. Transfer colors to UV texture requires non-overlapping UV layout fully contained in unit square on target mesh and material with active
Image Texture node with loaded image to operate on. Extending margins on UV texture uses blender baking system and requires
Cycles to be set as render engine.
Intersect or Exclude points with mesh object.
To use, switch shader type to
Color Adjustment. Adjust exposure, gamma, brightness, contrast, hue, saturation, value or invert colors.
Remove points with exact/similar color as chosen in color picker (Eyedropper works too).
Load another ply and merge with currently displayed.
Join current active point cloud with another on different object.
Only single point cloud per render/frame is supported. Output image is RGBA 8bit PNG - transparent background with colored point cloud, which can be composed over something else later.
Convert point cloud to mesh (each point to
Ico Sphere), instancer (with
Ico Sphere) or particle system (with
Ico Sphere). Point colors will be converted to vertex colors.
Generate point cloud from mesh (or object convertible to mesh) surface or volume.
Export current point cloud as binary ply file.
Load sequence of ply files to play in viewport.
You can choose tab name for PCV to keep things organized.
You can use PCV to display point cloud data from other addons/custom scripts. See documentation.
- viewport menu to batch control PCV instances
- Height Colors, Depth Effects and Alpha shaders
- load alpha, export alpha
- render with manual depth sorting
- fixed sequence animation render
- transfer colors from point cloud to mesh vertex colors or uv texture
- voxel simplification method
- generate points in mesh volume
- core completely rewritten
- takes less system memory
- better undo / redo handling
- partial ply loading - slice, evenly spaced or random strategies
- out of video memory crash prevention with maximum display points user setting
- more shader types and shader options (Phong, Billboard, Billboard Phong, Fresnel, Bounding Box, Position with scale and offset)
- render to image with any shader
- optional faster triangulated conversion to mesh
- many small fixes and optimizations
