| 3 | * raylib v5.5 - A simple and easy-to-use library to enjoy videogames programming (www.raylib.com) | ||
| 4 | * | ||
| 5 | * FEATURES: | ||
| 6 | * - NO external dependencies, all required libraries included with raylib | ||
| 7 | * - Multiplatform: Windows, Linux, FreeBSD, OpenBSD, NetBSD, DragonFly, | ||
| 8 | * MacOS, Haiku, Android, Raspberry Pi, DRM native, HTML5. | ||
| 9 | * - Written in plain C code (C99) in PascalCase/camelCase notation | ||
| 10 | * - Hardware accelerated with OpenGL (1.1, 2.1, 3.3, 4.3, ES2, ES3 - choose at compile) | ||
| 11 | * - Unique OpenGL abstraction layer (usable as standalone module): [rlgl] | ||
| 12 | * - Multiple Fonts formats supported (TTF, OTF, FNT, BDF, Sprite fonts) | ||
| 13 | * - Outstanding texture formats support, including compressed formats (DXT, ETC, ASTC) | ||
| 14 | * - Full 3d support for 3d Shapes, Models, Billboards, Heightmaps and more! | ||
| 15 | * - Flexible Materials system, supporting classic maps and PBR maps | ||
| 16 | * - Animated 3D models supported (skeletal bones animation) (IQM, M3D, GLTF) | ||
| 17 | * - Shaders support, including Model shaders and Postprocessing shaders | ||
| 18 | * - Powerful math module for Vector, Matrix and Quaternion operations: [raymath] | ||
| 19 | * - Audio loading and playing with streaming support (WAV, OGG, MP3, FLAC, QOA, XM, MOD) | ||
| 20 | * - VR stereo rendering with configurable HMD device parameters | ||
| 21 | * - Bindings to multiple programming languages available! | ||
| 22 | * | ||

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

| 3 | * rlgl v5.0 - A multi-OpenGL abstraction layer with an immediate-mode style API | ||
| 4 | * | ||
| 5 | * DESCRIPTION: | ||
| 6 | * An abstraction layer for multiple OpenGL versions (1.1, 2.1, 3.3 Core, 4.3 Core, ES 2.0) | ||
| 7 | * that provides a pseudo-OpenGL 1.1 immediate-mode style API (rlVertex, rlTranslate, rlRotate...) | ||
| 8 | * | ||
| 9 | * ADDITIONAL NOTES: | ||
| 10 | * When choosing an OpenGL backend different than OpenGL 1.1, some internal buffer are | ||
| 11 | * initialized on rlglInit() to accumulate vertex data | ||
| 12 | * | ||
| 13 | * When an internal state change is required all the stored vertex data is renderer in batch, | ||
| 14 | * additionally, rlDrawRenderBatchActive() could be called to force flushing of the batch | ||
| 15 | * | ||
| 16 | * Some resources are also loaded for convenience, here the complete list: | ||
| 17 | * - Default batch (RLGL.defaultBatch): RenderBatch system to accumulate vertex data | ||
| 18 | * - Default texture (RLGL.defaultTextureId): 1x1 white pixel R8G8B8A8 | ||
| 19 | * - Default shader (RLGL.State.defaultShaderId, RLGL.State.defaultShaderLocs) | ||
| 20 | * | ||
| 21 | * Internal buffer (and resources) must be manually unloaded calling rlglClose() | ||
| 22 | * | ||
| 23 | * CONFIGURATION: | ||
| 24 | * #define GRAPHICS_API_OPENGL_11 | ||
| 25 | * #define GRAPHICS_API_OPENGL_21 | ||
| 26 | * #define GRAPHICS_API_OPENGL_33 | ||
| 27 | * #define GRAPHICS_API_OPENGL_43 | ||
| 28 | * #define GRAPHICS_API_OPENGL_ES2 | ||
| 29 | * #define GRAPHICS_API_OPENGL_ES3 | ||
| 30 | * Use selected OpenGL graphics backend, should be supported by platform | ||
| 31 | * Those preprocessor defines are only used on rlgl module, if OpenGL version is | ||
| 32 | * required by any other module, use rlGetVersion() to check it | ||
| 33 | * | ||
| 34 | * #define RLGL_IMPLEMENTATION | ||
| 35 | * Generates the implementation of the library into the included file | ||
| 36 | * If not defined, the library is in header only mode and can be included in other headers | ||
| 37 | * or source files without problems. But only ONE file should hold the implementation | ||
| 38 | * | ||
| 39 | * #define RLGL_RENDER_TEXTURES_HINT | ||
| 40 | * Enable framebuffer objects (fbo) support (enabled by default) | ||
| 41 | * Some GPUs could not support them despite the OpenGL version | ||
| 42 | * | ||
| 43 | * #define RLGL_SHOW_GL_DETAILS_INFO | ||
| 44 | * Show OpenGL extensions and capabilities detailed logs on init | ||
| 45 | * | ||
| 46 | * #define RLGL_ENABLE_OPENGL_DEBUG_CONTEXT | ||
| 47 | * Enable debug context (only available on OpenGL 4.3) | ||
| 48 | * | ||
| 49 | * rlgl capabilities could be customized just defining some internal | ||
| 50 | * values before library inclusion (default values listed): | ||
| 51 | * | ||
| 52 | * #define RL_DEFAULT_BATCH_BUFFER_ELEMENTS 8192 // Default internal render batch elements limits | ||
| 53 | * #define RL_DEFAULT_BATCH_BUFFERS 1 // Default number of batch buffers (multi-buffering) | ||
| 54 | * #define RL_DEFAULT_BATCH_DRAWCALLS 256 // Default number of batch draw calls (by state changes: mode, texture) | ||
| 55 | * #define RL_DEFAULT_BATCH_MAX_TEXTURE_UNITS 4 // Maximum number of textures units that can be activated on batch drawing (SetShaderValueTexture()) | ||
| 56 | * | ||
| 57 | * #define RL_MAX_MATRIX_STACK_SIZE 32 // Maximum size of internal Matrix stack | ||
| 58 | * #define RL_MAX_SHADER_LOCATIONS 32 // Maximum number of shader locations supported | ||
| 59 | * #define RL_CULL_DISTANCE_NEAR 0.01 // Default projection matrix near cull distance | ||
| 60 | * #define RL_CULL_DISTANCE_FAR 1000.0 // Default projection matrix far cull distance | ||
| 61 | * | ||
| 62 | * When loading a shader, the following vertex attributes and uniform | ||
| 63 | * location names are tried to be set automatically: | ||
| 64 | * | ||
| 65 | * #define RL_DEFAULT_SHADER_ATTRIB_NAME_POSITION "vertexPosition" // Bound by default to shader location: RL_DEFAULT_SHADER_ATTRIB_LOCATION_POSITION | ||

| 72 | * #define RL_DEFAULT_SHADER_ATTRIB_NAME_BONEWEIGHTS "vertexBoneWeights" // Bound by default to shader location: RL_DEFAULT_SHADER_ATTRIB_LOCATION_BONEWEIGHTS | ||
| 73 | * #define RL_DEFAULT_SHADER_UNIFORM_NAME_MVP "mvp" // model-view-projection matrix | ||
| 74 | * #define RL_DEFAULT_SHADER_UNIFORM_NAME_VIEW "matView" // view matrix | ||
| 75 | * #define RL_DEFAULT_SHADER_UNIFORM_NAME_PROJECTION "matProjection" // projection matrix | ||
