Three.js stands out as a powerful WebGL-based 3D rendering engine, essentially functioning as a sophisticated library within the realm of web development.
What sets Three.js apart is its utilization of pure WebGL, eliminating the need for any form of conversion. The code is intelligently abstracted, making tasks like creating buffers, enabling vertex arrays, and crafting shaders a seamless process. With Three.js, loading models, selecting materials, and issuing draw calls become simple tasks.
While the foundation of Three.js lies in WebGL, the code is refined to enhance user-friendliness.
Comparing WebGL to OpenGL, it becomes evident that WebGL resembles an earlier iteration of OpenGL, particularly OpenGL 2.0 (ES). While new versions of OpenGL introduce numerous features, WebGL aligns closely with the OGL 2.0 specification. This similarity allows for easy conversion between OGL 2.0 and WebGL, despite some differences in features.
WebGL functions as a JavaScript API, requiring developers to write WebGL-specific functions in JavaScript to communicate with the GPU. Therefore, JavaScript serves as the primary language for developing browser-compatible 3D applications, with WebGL acting as the intermediary between JavaScript and the GPU.
For those looking to convert Three.js into WebGL code and subsequently into OpenGL, the process should be relatively straightforward, particularly when dealing with drawing API functions. Nevertheless, translating data structures could present challenges.
When considering the conversion from OpenGL to DirectX, the complexity increases significantly due to the contrasting nature of the APIs. While OpenGL functions as a state machine, DirectX adopts object-oriented principles, resulting in disparities in function names and data structures.
