/********************************************************************************************** * * rlgl v5.0 - A multi-OpenGL abstraction layer with an immediate-mode style API * * DESCRIPTION: * An abstraction layer for multiple OpenGL versions (1.1, 2.1, 3.3 Core, 4.3 Core, ES 2.0) * that provides a pseudo-OpenGL 1.1 immediate-mode style API (rlVertex, rlTranslate, rlRotate...) * * ADDITIONAL NOTES: * When choosing an OpenGL backend different than OpenGL 1.1, some internal buffer are * initialized on rlglInit() to accumulate vertex data * * When an internal state change is required all the stored vertex data is renderer in batch, * additionally, rlDrawRenderBatchActive() could be called to force flushing of the batch * * Some resources are also loaded for convenience, here the complete list: * - Default batch (RLGL.defaultBatch): RenderBatch system to accumulate vertex data * - Default texture (RLGL.defaultTextureId): 1x1 white pixel R8G8B8A8 * - Default shader (RLGL.State.defaultShaderId, RLGL.State.defaultShaderLocs) * * Internal buffer (and resources) must be manually unloaded calling rlglClose() * * CONFIGURATION: * #define GRAPHICS_API_OPENGL_11 * #define GRAPHICS_API_OPENGL_21 * #define GRAPHICS_API_OPENGL_33 * #define GRAPHICS_API_OPENGL_43 * #define GRAPHICS_API_OPENGL_ES2 * #define GRAPHICS_API_OPENGL_ES3 * Use selected OpenGL graphics backend, should be supported by platform * Those preprocessor defines are only used on rlgl module, if OpenGL version is * required by any other module, use rlGetVersion() to check it * * #define RLGL_IMPLEMENTATION * Generates the implementation of the library into the included file * If not defined, the library is in header only mode and can be included in other headers * or source files without problems. But only ONE file should hold the implementation * * #define RLGL_RENDER_TEXTURES_HINT * Enable framebuffer objects (fbo) support (enabled by default) * Some GPUs could not support them despite the OpenGL version * * #define RLGL_SHOW_GL_DETAILS_INFO * Show OpenGL extensions and capabilities detailed logs on init * * #define RLGL_ENABLE_OPENGL_DEBUG_CONTEXT * Enable debug context (only available on OpenGL 4.3) * * rlgl capabilities could be customized just defining some internal * values before library inclusion (default values listed): * * #define RL_DEFAULT_BATCH_BUFFER_ELEMENTS 8192 // Default internal render batch elements limits * #define RL_DEFAULT_BATCH_BUFFERS 1 // Default number of batch buffers (multi-buffering) * #define RL_DEFAULT_BATCH_DRAWCALLS 256 // Default number of batch draw calls (by state changes: mode, texture) * #define RL_DEFAULT_BATCH_MAX_TEXTURE_UNITS 4 // Maximum number of textures units that can be activated on batch drawing (SetShaderValueTexture()) * * #define RL_MAX_MATRIX_STACK_SIZE 32 // Maximum size of internal Matrix stack * #define RL_MAX_SHADER_LOCATIONS 32 // Maximum number of shader locations supported * #define RL_CULL_DISTANCE_NEAR 0.01 // Default projection matrix near cull distance * #define RL_CULL_DISTANCE_FAR 1000.0 // Default projection matrix far cull distance * * When loading a shader, the following vertex attributes and uniform * location names are tried to be set automatically: * * #define RL_DEFAULT_SHADER_ATTRIB_NAME_POSITION "vertexPosition" // Bound by default to shader location: RL_DEFAULT_SHADER_ATTRIB_LOCATION_POSITION * #define RL_DEFAULT_SHADER_ATTRIB_NAME_TEXCOORD "vertexTexCoord" // Bound by default to shader location: RL_DEFAULT_SHADER_ATTRIB_LOCATION_TEXCOORD * #define RL_DEFAULT_SHADER_ATTRIB_NAME_NORMAL "vertexNormal" // Bound by default to shader location: RL_DEFAULT_SHADER_ATTRIB_LOCATION_NORMAL * #define RL_DEFAULT_SHADER_ATTRIB_NAME_COLOR "vertexColor" // Bound by default to shader location: RL_DEFAULT_SHADER_ATTRIB_LOCATION_COLOR * #define RL_DEFAULT_SHADER_ATTRIB_NAME_TANGENT "vertexTangent" // Bound by default to shader location: RL_DEFAULT_SHADER_ATTRIB_LOCATION_TANGENT * #define RL_DEFAULT_SHADER_ATTRIB_NAME_TEXCOORD2 "vertexTexCoord2" // Bound by default to shader location: RL_DEFAULT_SHADER_ATTRIB_LOCATION_TEXCOORD2 * #define RL_DEFAULT_SHADER_ATTRIB_NAME_BONEIDS "vertexBoneIds" // Bound by default to shader location: RL_DEFAULT_SHADER_ATTRIB_LOCATION_BONEIDS * #define RL_DEFAULT_SHADER_ATTRIB_NAME_BONEWEIGHTS "vertexBoneWeights" // Bound by default to shader location: RL_DEFAULT_SHADER_ATTRIB_LOCATION_BONEWEIGHTS * #define RL_DEFAULT_SHADER_UNIFORM_NAME_MVP "mvp" // model-view-projection matrix * #define RL_DEFAULT_SHADER_UNIFORM_NAME_VIEW "matView" // view matrix * #define RL_DEFAULT_SHADER_UNIFORM_NAME_PROJECTION "matProjection" // projection matrix * #define RL_DEFAULT_SHADER_UNIFORM_NAME_MODEL "matModel" // model matrix * #define RL_DEFAULT_SHADER_UNIFORM_NAME_NORMAL "matNormal" // normal matrix (transpose(inverse(matModelView))) * #define RL_DEFAULT_SHADER_UNIFORM_NAME_COLOR "colDiffuse" // color diffuse (base tint color, multiplied by texture color) * #define RL_DEFAULT_SHADER_UNIFORM_NAME_BONE_MATRICES "boneMatrices" // bone matrices * #define RL_DEFAULT_SHADER_SAMPLER2D_NAME_TEXTURE0 "texture0" // texture0 (texture slot active 0) * #define RL_DEFAULT_SHADER_SAMPLER2D_NAME_TEXTURE1 "texture1" // texture1 (texture slot active 1) * #define RL_DEFAULT_SHADER_SAMPLER2D_NAME_TEXTURE2 "texture2" // texture2 (texture slot active 2) * * DEPENDENCIES: * - OpenGL libraries (depending on platform and OpenGL version selected) * - GLAD OpenGL extensions loading library (only for OpenGL 3.3 Core, 4.3 Core) * * * LICENSE: zlib/libpng * * Copyright (c) 2014-2024 Ramon Santamaria (@raysan5) * * This software is provided "as-is", without any express or implied warranty.
