b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	3 * raymath v2.0 - Math functions to work with Vector2, Vector3, Matrix and Quaternions
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	4 *
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	5 * CONVENTIONS:
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	6 * - Matrix structure is defined as row-major (memory layout) but parameters naming AND all
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	7 * math operations performed by the library consider the structure as it was column-major
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	8 * It is like transposed versions of the matrices are used for all the maths
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	9 * It benefits some functions making them cache-friendly and also avoids matrix
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	10 * transpositions sometimes required by OpenGL
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	11 * Example: In memory order, row0 is [m0 m4 m8 m12] but in semantic math row0 is [m0 m1 m2 m3]
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	12 * - Functions are always self-contained, no function use another raymath function inside,
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	13 * required code is directly re-implemented inside
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	14 * - Functions input parameters are always received by value (2 unavoidable exceptions)
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	15 * - Functions use always a "result" variable for return (except C++ operators)
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	16 * - Functions are always defined inline
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	17 * - Angles are always in radians (DEG2RAD/RAD2DEG macros provided for convenience)
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	18 * - No compound literals used to make sure the library is compatible with C++
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	19 *
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	20 * CONFIGURATION:
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	21 * #define RAYMATH_IMPLEMENTATION
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	22 * Generates the implementation of the library into the included file
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	23 * If not defined, the library is in header only mode and can be included in other headers
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	24 * or source files without problems. But only ONE file should hold the implementation
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	25 *
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	26 * #define RAYMATH_STATIC_INLINE
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	27 * Define static inline functions code, so #include header suffices for use
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	28 * This may use up lots of memory
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	29 *
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	30 * #define RAYMATH_DISABLE_CPP_OPERATORS
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	31 * Disables C++ operator overloads for raymath types.
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	32 *
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	33 * #define RAYMATH_USE_SIMD_INTRINSICS 1
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	34 * Try to enable SIMD intrinsics for MatrixMultiply()
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	35 * Note that users enabling it must be aware of the target platform where application will
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	36 * run to support the selected SIMD intrinsic, for now, only SSE is supported
