I need to create a 3D voxel grid to store, analyze and display point cloud values. For example, I need to know which voxel cubes each point in the point cloud falls into and I need to be able to access the original coordinates of the points. I need the voxel spacing to be of variable size to increase or reduce detail. Unlike other programming languages Matlab does not seem to have any built in voxel functions.

Any help would be appreciated.

I dont know what kind of pictures you mean. I need something like the attached heatmap but in 3D instead of 2D and with voxels instead of pixels.

Hi there!

I need to embed the data in 3D image. As i selected the image of point cloud but I'm stuck in accessing point from point cloud.

please help me!

You plot each voxel manually
