You are welcome to contribute to this work. 4 | 5 | There are no hard rules for contributions, except that code should be easily readable and commit messages sensible. Other than that, we prefer to let contributors express themselves. 6 | 7 | #### Lottie JSON schema 8 | 9 | A visual map of the JSON schema for lottie animations can be found in [lottie_json_map.pdf](doc/lottie_json_map.pdf). This schema has been created based on the JSON schema found at https://github.com/airbnb/lottie-web/tree/master/docs/json. 10 | 11 | Naming conventions used in Glottie, that conform to this schema, are [detailed here](doc/naming_convention.md). 12 | 13 | #### Glottie innards 14 | 15 | The following are some basic documentation on the inner workings of Glottie. 16 | 17 | The first of these explains the [execution sequence](doc/executionsequence.md), by presenting the call sequence to the main functions, starting with the entry point *main()*. 18 | 19 | The next important primer explains how [Glottie's state machine](doc/statemachine.md) works. 20 | 21 | Once Glottie's state-machine builds a scene graph, the shape data is used to [compute geometries and transformations](doc/geometry.md). 22 | 23 | Next, the [transformations are sequenced](doc/animation.md). 24 | 25 | Finally, the [geometries are rendered](doc/render.md) as per the transformation sequences. 26 | 27 | -------------------------------------------------------------------------------- /debugtools.cpp: -------------------------------------------------------------------------------- 1 | ///////////////////////////////////////////////////////// 2 | ///////// ///////// 3 | ///////// ****** ***************** ///////// 4 | ///////// **** *************** ///////// 5 | ///////// *** *** ** ///////// 6 | ///////// *** *** ///////// 7 | ///////// *** *** ** ///////// 8 | ///////// *** ********** ///////// 9 | ///////// *** ********** ///////// 10 | ///////// *** *** ** ///////// 11 | ///////// *** *** ///////// 12 | ///////// *** ** *** ///////// 13 | ///////// ************** ***** ///////// 14 | ///////// **************** ******* ///////// 15 | ///////// ///////// 16 | ///////////////////////////////////////////////////////// 17 | /////// Created by: https://github.com/shaafiee /////// 18 | /////// Copyright 2020, lottiefiles.com /////// 19 | ///////////////////////////////////////////////////////// 20 | 21 | void debugNestedArray(struct ValuesVector* passedArray, int nestLevel) { 22 | bool exhausted = false;

Next this eased transformation data is converted into matrices. These matrices are then added to the respective frames of the animation ([transform.cpp](../animate/transform.cpp)). 10 | 11 | #### Transformations for layers 12 | 13 | Layers transformations are done after all the [geometry](geometry.md) data has been built. The function called to compose the layer transformations is *prepTransformShapes()* ([prep_transform.cpp](../animate/prep_transform.cpp)), which finds all the layers with transformations. 14 | 15 | In any are found, then *composeTransformLayers()* ([transform.cpp](../animate/transform.cpp)) is called. This function goes through the almost the exact same process as *fillTransformShapes()* ([transform.cpp](../animate/transform.cpp) to compose layer transformations. 16 | 17 | At the end of this stage, all the transformation matrices will have been added to the global linked list *animationSequence*, with each transformation matrix slotted into its relevant frame. -------------------------------------------------------------------------------- /doc/bezier.md: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/LottieFiles/glottie/a3cd0d8e4e03d169cb2fc642ebd1f292e9ad7cab/doc/bezier.md -------------------------------------------------------------------------------- /doc/borders.md: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/LottieFiles/glottie/a3cd0d8e4e03d169cb2fc642ebd1f292e9ad7cab/doc/borders.md -------------------------------------------------------------------------------- /doc/drawsequence.md: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/LottieFiles/glottie/a3cd0d8e4e03d169cb2fc642ebd1f292e9ad7cab/doc/drawsequence.md -------------------------------------------------------------------------------- /doc/earcutting.md: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/LottieFiles/glottie/a3cd0d8e4e03d169cb2fc642ebd1f292e9ad7cab/doc/earcutting.md -------------------------------------------------------------------------------- /doc/executionsequence.md: -------------------------------------------------------------------------------- 1 | # Execution sequence 2 | 3 | Glottie's execution sequence is listed in the following table: 4 | 5 | File|Purpose 6 | ----|------- 7 | [main.cpp](../main.cpp)|Program entry point: main()→readFromStdin()→loadJson() 8 | [deserializer/deserializer.cpp](../deserializer/deserializer.cpp)|State machine that deserializes the JSON file into a scene graph: deserializeChar()→checkCharacter()→... 9 | [gl/gl.init](../gl/gl.init)|Initialize OpenGL system: glInit(), glInitShaders() 10 | [gl/parentage.cpp](../gl/parentage.cpp)|Resolve parenting and order scene graph accordingly: parentShapes()→... 11 | [gl/prep.cpp](../gl/prep.cpp)|Discover geometric elements, generate their vertex buffers and compute transformations: prepShapes()→prepAssets()→prepLayers()→(findLayersTransform()→[animate/transform.cpp](../animate/transform.cpp):fillTransformLayers())→prepShapesItem()→(findShapesTransform()→[animate/transform.cpp](../animate/transform.cpp):fillTransformShapes())→prepPropertiesShape()→prepPropertiesShapeProp()→prepTriangulate()→prepVAO() 12 | [animate/prep_transform.cpp](../animate/prep_transform.cpp)|Presequence all transformations and add them to the scene graph: prepTransformShapes()→→prepTransformLayers()→[animate/transform.cpp](../animate/transform.cpp):composeTransformLayers()→[animate/transform.cpp](../animate/transform.cpp):fillCompositeAnimation() 13 | [main.cpp](../main.cpp)|Setup animation looping: either mainloop() or standaloneLoop() 14 | [gl/gl.cpp](../gl/gl.cpp)|Draw loop: glDraw() 15 | -------------------------------------------------------------------------------- /doc/geometry.md: -------------------------------------------------------------------------------- 1 | ## Geometry 2 | 3 | Building geometries begins with the function *fillPropertiesShapeProp()* ([properties.cpp](../deserializer/properties.cpp)), which is the function that fills the geometry data into a given shape object in the scene graph. Once the function fills this data for a shape, then from within the same function a call is made to *bezierSegment()* ([misc.cpp](../misc.cpp)), which is an easing function for bezier curves. 4 | 5 | The next part of the geometry begins after all data is extracted from the source JSON. Once this is done, the function *prepShapes()* ([prep.cpp](../gl/prep.cpp)) is called. This function finds the relevant data in the scene graph needed to build the geometries in the lottie animation. 6 | 7 | All geometry data found is passed to the function *prepTriangulate()* ([triangulate.cpp](../gl/triangulate.cpp)). This function accomplishes two things. Firstly, it cuts away a geometry's ears, yielding a set of simple shapes that together constitute the full geometry. Secondly, each one of these shapes is triangulated. The triangulated shapes are then passed to *prepVAO()* ([prep.cpp](../gl/prep.cpp)), which creates a vertex buffer object (VBO) from the triangulated shapes. 8 | -------------------------------------------------------------------------------- /doc/lottie_json_map.pdf: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/LottieFiles/glottie/a3cd0d8e4e03d169cb2fc642ebd1f292e9ad7cab/doc/lottie_json_map.pdf -------------------------------------------------------------------------------- /doc/naming_convention.md: -------------------------------------------------------------------------------- 1 | ## Naming conventions in Glottie 2 | 3 | The naming conventions in the [lottie_json_map.pdf](../doc/lottie_json_map.pdf) has been followed throughout the source code. For instance, the *properties/offsetKeyframe.json* leaf object in the top-right corner of the schema map is named `PropertiesOffsetKeyframe` in Glottie code. This is shown in the following snippet from [properties.h](../deserializer/properties.h) [line 60]): 4 | 5 | ```c++ 6 | #ifdef EMT 7 | struct alignas(ALIGNSIZE) PropertiesOffsetKeyframe { 8 | #else 9 | struct PropertiesOffsetKeyframe { 10 | #endif 11 | struct PropertiesOffsetKeyframe* start = NULL; 12 | struct PropertiesOffsetKeyframe* next = NULL; 13 | struct PropertiesOffsetKeyframe* prev = NULL; 14 | 15 | struct BezierCurve* i = NULL; 16 | struct BezierCurve* o = NULL; 17 | float* s; // start value 18 | int s_count; 19 | float t = 0; // start time 20 | float* ti; 21 | int ti_count; 22 | float* to; 23 | int to_count; 24 | } *currentPropertiesOffsetKeyframe; 25 | ``` 26 | 27 | The corresponding functions for *properties/offsetKeyframe.json* uses the naming convention <purpose>PropertiesOffsetKeyframe (with the function name beginning with a lowercase letter). A function is illustrated in the following snippet ([properties.cpp](../deserializer/properties.cpp) [line 80]): 28 | 29 | ```c++ 30 | struct PropertiesOffsetKeyframe* newPropertiesOffsetKeyframe() { 31 | if (currentPropertiesOffsetKeyframe == NULL) { 32 | currentPropertiesOffsetKeyframe = new PropertiesOffsetKeyframe; 33 | currentPropertiesOffsetKeyframe->start = currentPropertiesOffsetKeyframe; 34 | } 35 | else { 36 | currentPropertiesOffsetKeyframe->next = new PropertiesOffsetKeyframe; 37 | currentPropertiesOffsetKeyframe->next->start = currentPropertiesOffsetKeyframe->start; 38 | currentPropertiesOffsetKeyframe->next->prev = currentPropertiesOffsetKeyframe; 39 | currentPropertiesOffsetKeyframe = currentPropertiesOffsetKeyframe->next; 40 | } 41 | return currentPropertiesOffsetKeyframe; 42 | } 43 | ``` -------------------------------------------------------------------------------- /doc/render.md: -------------------------------------------------------------------------------- 1 | ## Rendering the Animation 2 | 3 | Glottie uses shaders to render its OpenGL animations. Its fragment shader is at [gl.cpp](../gl/gl.cpp#L25), while its vertex shader is imported at [gl.cpp](../gl/gl.cpp#L23) from [vertexShader.cpp](../gl/vertexShader.cpp), which is a file generated by [generate_glsl.pl](../gl/generate_glsl.pl). 4 | 5 | Animation rendering begins with the function [mainloop()](../main.cpp) when Glottie is compiled for Web Assembly. For all other cases rendering begins with the function [standaloneLoop()](../main.cpp). 6 | 7 | The function *mainloop()* is used as the callback function for emscripten_set_main_loop(). 8 | 9 | Both *mainloop()* and *standaloneLoop()* calls [glDraw()](../gl/gl.cpp) perform the rendering. 10 | -------------------------------------------------------------------------------- /doc/shapes.md: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/LottieFiles/glottie/a3cd0d8e4e03d169cb2fc642ebd1f292e9ad7cab/doc/shapes.md -------------------------------------------------------------------------------- /doc/statemachine.md: -------------------------------------------------------------------------------- 1 | ## Glottie State-Machine 2 | 3 | Glottie implements a dual-stage state-machine to extract animation data from a JSON string into a scene graph. The entry point for the state machine is in the function [deserializer.cpp](../deserializer/deserializer.cpp):deserializeChar(). 4 | 5 | In the first stage of the state-machine, the state-machine's states are dictated by JSON syntax. For instance, **{** changes the machine's state to *object opened*. When **"** follows immediately after that, then the state changes to *key opened*, and the very next **"** indicates *key closed* - meaning, all the characters that came in-between these two states constitute the key name. 6 | 7 | The next **:** changes the state to *reading a value* and, making the state-machine interpret the string enclosed by the next double-quotes as the value corresponding to the last key found. Once a key-value pair is discovered, the state-machine adds it to the linked list *theScope->currentKeyValueTrail->keyValue* ([deserializer.cpp](..deserializer/deserializer.cpp)). 8 | 9 | #### Filling the scene graph 10 | 11 | As mentioned before, the Glottie state-machine has dual stages, the first for extracting the data in the source JSON and the second for filling the scene graph. This second stage is triggered on two conditions: when either **{** or **}** are encountered. 12 | 13 | When **{** is encountered, the state-machine calls *prepareContainer()* ([associate.cpp](../deserializer/associate.cpp)) to create a new container in the scene graph for storing all the key-values in the current object. What type of container to create, and therefore, which parent node to attach this newly created container, is determined by the global linked list *theScope*. 14 | 15 | When the corresponding **}** is encountered, the state-machine calls *associateKeyValues()* ([associate.cpp](../deserializer/associate.cpp)) to finally store all the key-values in the newly created container. Once again, the global linked list *theScope* is used to determine what key-value storage function to call. For instance, if the enums stored in the last 3 elements of *theScope* linked list were **_p**, **_ks** and **_layers**, then the storage function called is *fillPropertiesMultiDimensional()* ([properties.cpp](../deserializer/properties.cpp)). -------------------------------------------------------------------------------- /doc/triangulate.md: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/LottieFiles/glottie/a3cd0d8e4e03d169cb2fc642ebd1f292e9ad7cab/doc/triangulate.md -------------------------------------------------------------------------------- /examples/.DS_Store: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/LottieFiles/glottie/a3cd0d8e4e03d169cb2fc642ebd1f292e9ad7cab/examples/.DS_Store -------------------------------------------------------------------------------- /examples/wasm/player.wasm: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/LottieFiles/glottie/a3cd0d8e4e03d169cb2fc642ebd1f292e9ad7cab/examples/wasm/player.wasm -------------------------------------------------------------------------------- /examples/wasm/serve_this: -------------------------------------------------------------------------------- 1 | #!/bin/bash 2 | 3 | if [ "$1" == "1" ]; then 4 | cp ../player.js ./ 5 | cp ../player.wasm ./ 6 | fi 7 | 8 | if [ "$(uname)" == "Linux" ]; then 9 | python3 -m http.server 8082 10 | else 11 | python3 -m http.server 8082 12 | fi 13 | -------------------------------------------------------------------------------- /glm/detail/_fixes.hpp: -------------------------------------------------------------------------------- 1 | /// @ref core 2 | /// @file glm/detail/_fixes.hpp 3 | 4 | #include 5 | 6 | //!
