glamx 0.1.0
Physics-oriented extensions of glam (Rot2, Pose2, Pose3, SdpMatrix, symmetric eigen): port of Dimforge glamx on the fixed Q32.32 scalar
Readme
glamx
Port of Dimforge glamx 0.3.1 to Cairo on top of
glam and the fixed Q32.32 scalar: Rot2, Rot3, Pose2, Pose3,
symmetric positive-definite matrices and the symmetric 3x3 eigen-decomposition, i.e. the math
layer parry and rapier are written against.
Scope: docs/research/06-glamx-scope.md.
Progress: docs/PORTING_STATUS.md. Compatible with Cairo 2.19.4.
Gas
Sierra gas (l2 gas, what a transaction pays) and prover cost (steps, range checks) of one call, net of the test overhead (X__op - X__base, see scripts/bench.py), measured with scarb 2.19.4, starknet-foundry 0.61.0 (.tool-versions). Source of truth: gas/*.snap; this region is generated by scripts/gas_tables.py, do not edit it.
