glamx 0.4.1

Physics-oriented extensions of glam (Rot2, Pose2, Pose3, SdpMatrix, symmetric eigen): port of Dimforge glamx on the fixed Q32.32 scalar

Readme

glamx

Pure Cairo port of Dimforge's glamx 0.3.1 on the fixed Q32.32 scalar and glam: Rot2, Rot3, Pose2, Pose3, SdpMatrix2, SdpMatrix3 and SymmetricEigen3.

[dependencies]
glamx = "0.4.1"

Compatible with Cairo 2.19.4. It depends on glam_core and fixed (not on the glam facade). glamx values interoperate with glam facade users: glam::vec3::Vec3, glam::quat::Quat, glam::mat4::Mat4 and the other facade types are the glam_core types glamx takes and returns.

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.
