In the previous article on 3D point cloud for FMX, systematic memory copy when drawing primitives came out as #1 bottleneck in FMX performance when rendering millions of points.
But was it just a false positive ?
I hacked FMXU.Context.DX11 to eliminate the memory copies… in the most hacky way, don’t ask for code it’s not re-useable 🙂 (more…)
With Delphi 12.Community Edition released not too long ago, it was an opportunity to test run what’s possible with FMX on the 3D side.
And while Delphi FireMonkey has 3D support, it’s not really a core feature. For a test run, the simplest of all 3D entities, a point cloud can serve as a decent stress test.
Point Clouds are now ubiquitous with the advent of 3D capture devices, which go from LIDAR to RGB-D cameras and all kinds of AI augmented approaches. So there is a plethora of 3D point cloud datasets out there.
