Matlab plot 3d matrix.

I am hoping to create a 3D plot for a data set (a 3D matrix) where each voxel has four pieces of data: an x position, y position, z position, and intensity. I would like to create a scatter plot (or other type of intensity map) where each point is appropriately located, and its colour relates its value.

Vote. 0. I already made a figure with. mesh (x,y,Z) where as Z has the size of length (x) by length (y). Now i want exactly the same, but only with discrete points. already tried scatter3 but it needs 3 vectors, all of the same length. Basically I need something like stem3 (x,y,Z) but without the stems. Is there really no solution?Link. Commented: Amit Kumar on 14 Oct 2020. given a 2D matrix of size ( x * y ) where each element contains a numeric value Z , how to plot the Z value in a 3D graph as a function of both x and y such that Z = matrix (x,y) ? I have tried using meshgrid to create a 2D array of size (x,y) and defined a new function F = matrix (x,y) and finally ...Artists can render a 3D design from a 2D one with a 3D modeling program. After producing a 2D design, an artist will use the 3D modeling program's tools to project the design into ... R = sqrt(X.^2 + Y.^2) + eps; The matrix R contains the distance from the center of the matrix, which is the origin. Adding eps prevents the divide by zero (in the next step) that produces Inf values in the data. Forming the sinc function and plotting Z with mesh results in the 3-D surface. Z = sin(R)./R;
