How to create point cloud with colour
显示 更早的评论
Hello,
I am trying to export a pointcloud as a .ply or .wrl to view in another program such as Meshlab. I have two arrays of equal size (vertices and colors(RGB)) . I can create a mesh using the vertices array, but when viewing the pointcloud it is monochrome. So, my question is how do I add the colour values to the vertices, to end up with a color appropriate pointcloud? I've looked into texture mapping, but I have not been successful with the surf and mesh functions. Any help is appreciated.

Try
1. " pointCloud": This makes a point cloud from 3D points and texture
ptCloud = pointCloud(xyzPoints, 'Color', alignedColorImage); % 3D colored point cloud
Then use
2. " pcwrite": This exports the point cloud as a PLY file with color informatoion
pcwrite(ptCloud,'Ply_file_name','PLYFormat','binary'); % Convert to .PLY format
Hope this helps

patch() allows you to assign vertex color.
Or, more directly, scatter3(x, y, z, pointsize, color)
