This patch adds support for PLY files that contain additional elements beyond the standard vertex data, such as camera intrinsic/extrinsic matrices embedded by tools like Apple's SHARP. Changes: - Parse properties only within vertex elements, ignoring others - Limit DataView to exact vertex data size to prevent bounds errors - Maintain full backward compatibility with standard PLY files Fixes issues with PLY files from SHARP and other tools that embed camera or metadata elements in the PLY format.

This patch adds support for PLY files that contain additional elements beyond the standard vertex data, such as camera intrinsic/extrinsic matrices embedded by tools like Apple's SHARP.
Currently, the viewer fails to load PLY files from SHARP and other tools that embed camera or metadata elements in the PLY format, showing 'offset is outside the bounds of the DataView' errors.
The fix parses properties only within vertex elements while ignoring additional elements, and limits the DataView to the exact vertex data size to prevent bounds errors. This maintains full backward compatibility with standard Gaussian splat PLY files.
Tested with both standard PLY files (which continue to work unchanged) and SHARP-generated PLY files (which now load successfully). No performance impact on existing functionality.
