In this article we will talk about both the WebGL and the Three JS. Their pros and cons, and the use cases each one of them have compared to the other one. Before we start comparing these two, it is important to notice that the Three.js library is based on WebGL and in this respect, there are not many difference in terms of their use cases. However, there must be a reason why Three.js has a lot more fans than WebGL these days and on the other hand, some developers still prefer WebGL to Three JS. This question is mostly asked by the beginners and the newbies, who are looking forward to start with one of these libraries and have still no clue which one is better or which one is easier. There are many answers to this question on various forums, but if you are still confused about the right answer, this article is written for you. So do not forget to follow along with this one and read the article till the end. In this article, we will cover the similarities and the differences of each of these libraries and hopefully you will find the right answer to your question.
Features supported by three jsIf you want to see if the Three.js library is the appropriate one for your design, it is highly recommended that you look at the features supported in Three.js: 1. Effects: Anaglyph, cross-eyed, and parallax barrier. 2. Scenes: add and remove objects at run-time; fog 3. Cameras: perspective and orthographic; 4. controllers: trackball, FPS, path and more 5. Animation: armatures, forward kinematics, inverse kinematics, morph, and keyframe Arashtad.com Design and development solutions arashtad 6. Lights: ambient, direction, point, and spot lights; shadows: cast and receive 7. Materials: Lambert, Phong, smooth shading, textures, and more 8. Shaders: access to full OpenGL Shading Language (GLSL) capabilities 9. Objects: meshes, particles, sprites, lines, ribbons, bones, and more – all with Level of detail 10. Geometry: plane, cube, sphere, torus, 3D text, and more; modifiers: lathe, extrude, and tube 11. Data loaders: binary, image, JSON, and scene 12. Utilities: full set of time and 3D math functions including frustum, matrix, quaternion, UVs, and more 13. Export and import: utilities to create Three.js-compatible JSON files from within: Blender, openCTM, FBX, Max, and OBJ 14. Support: API documentation is under construction. A public forum and wiki is in full operation. 15. Examples: Over 150 files of coding examples plus fonts, models, textures, sounds, and other support files 16. Debugging: Stats.js, WebGL Inspector, Three.js Inspector Virtual and Augmented Reality via WebXR
ConclusionIn this article, we have talked about Webgl and Three.js libraries, their use cases, tools, features, and alternatives. Moreover, we introduced Three.js as a library built on top of WebGL. WebgL on the other hand is a low-level library that gives the developer many capabilities and at the same makes the design process much harder compared to higher-level libraries like Three JS. Furthermore, both Three.js and Webgl use GLSL language to design shaders for a greater variety of effects that are more customized. Hope this article has helped you find the appropriate library of your choice. However, there are not many differences between WebGL and Three.js. Three.js saves a lot of time for you considering that it is a higher level library, on the other hand, WebGL gives you more capabilities and options in spite of being more complex
