Add README.md for each library module documenting API, platform backends, and usage. Add .gitignore for build artifacts. Remove pre-built binaries from version control. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
libsst-random
Pseudorandom number generation and simplex noise in C.
PRNG algorithms
| Type | Enum | State size |
|---|---|---|
| Mersenne Twister | SST_PRNG_MERSENNE |
624 x 32-bit |
| CMWC | SST_PRNG_CMWC |
4096 x 32-bit |
| SmallPRNG | SST_PRNG_SMALLPRNG |
4 x 32-bit |
Generic API
SST_PRNG rng = SST_Random_CreatePRNGFromSeed(SST_PRNG_MERSENNE, 42);
float f = SST_Random_GetPRNGFloat(rng, 0.0f, 1.0f);
int i = SST_Random_GetPRNGInt(rng, 0, 100);
SST_Random_DestroyPRNG(rng);
Each algorithm also has direct-access functions
(SST_Random_*SmallPRNG*, SST_Random_*CMWC*).
Array-fill variants are provided for batch generation.
Simplex noise
1D through 4D simplex noise, returning values in [-1, 1]:
