To plot millions of 3D points efficiently, MATLAB’s built-in graphics can work quite well.
The below code snippet generates 1 million random 3D points and uses "scatter" to plot them:
% Generate 1 million random 3D points
N = 1e6;
x = rand(1, N) * 100;
y = rand(1, N) * 100;
z = rand(1, N) * 100;
% Use scatter3 with performance optimizations
figure
scatter3(x, y, z, 1, '.', 'MarkerEdgeAlpha', 0.1);
xlabel('X');
ylabel('Y');
zlabel('Z');
title('Large 3D Point Cloud');
view(3);
axis equal;
The output of the code snippet:
I hope this helps!
