LeoVCG

Leopard/PPC VCGlib baseline

LeoVCG verifies whether unmodified VCGlib can be used on Mac OS X Leopard 10.5.8 / PowerPC.

Current baseline result:

  • VCGlib remains unchanged under vendor/vcglib.
  • GCC10 is used only as a quarantined C/C++ specialist compiler.
  • Probe binaries are linked with -static-libstdc++ -static-libgcc.
  • Runtime dependencies are limited to /usr/lib/libSystem.B.dylib.
  • Eigen vectorization is disabled for the scalar baseline.
  • PLY write/read/roundtrip works.
  • ASCII STL write/read/roundtrip works.
  • Binary STL roundtrip works locally, but binary STL export appears to be big-endian on PowerPC and is not accepted as a portable output path.

See:

  • docs/LEOPARD-VCGLIB-BASELINE.md
  • docs/findings/

About

LeoVCG is a Leopard/PPC-tailored VCGlib platform: unmodified VCGlib core, curated build policy, scalar baseline, tested mesh I/O paths, and Leopard-specific safeguards.
