webgl-framework VS three.js

After the terrain we draw a sky hemisphere object with the basic DiffuseShader, and then draw 11 cloud sprites. Then we draw a sun sprite. These transparent objects are rendered without writing to the depth buffer. Clouds and sun have trimmed geometries for less overdraw. You can read about this optimized sprites technique here. We decided not to use soft particles for clouds because scene size allowed us to place them so that they don’t intersect with other geometries while still partially occluding some peaks. Not using soft particles is beneficial for performance because they require additional render pass to render scene depth.

Historically, the web demo was created first — it was used as a prototyping playground to compose a scene and to fine-tune shaders. Also, this really helps in sharing work between a team of two people without necessity to learn Android Studio for both. And when everything was polished and looked good enough, an Android app was created quite fast based on the web demo code. Porting code to Android is a quite straightforward and easy process because our WebGL framework has the same method signatures as the framework used in Android apps.

Regarding the optimization of the effect, I found an issue on the three.js GitHub repository: https://github.com/mrdoob/three.js/issues/14104 The alpha channel issue seems to be a difficult problem, which has been present since 2018. At the end of the discussion, a solution proposed by a contributor is not to modify the UnrealBloomPass but to blend the source texture and target texture in the shader.

Here's how we used Three.js to place and find affirmations in the sky.

Three.js is dedicated to generating 3D visuals, offering a powerful suite of features and tools. It is built atop WebGL and optimizes GPU usage for rapid rendering, ensuring smooth performance across devices, including those with limited resources. Three.js's versatility allows for the creation of a vast spectrum of 3D graphics and animations, ranging from simple shapes to intricate models.

Most of frontend libraries are made with Vanilla JS. An example of library that you might frequently use is "Chart.js". But React is not compatible with Chart.js so here it comes "React-chartjs-2" A wrapper library to work with Chart.js in React ecosystem. Oh you want to use "three.js" for some cool 3D? you will need "React-three/fiber". In my case, I need to implement "telegram-web-app", not so fast, I have to create my own wrapper to be able to use it.

For one of my 100-Day Challenges, I chose to dive into Three.js, a JavaScript 3D library. It's easy to start learning, and it becomes difficult to master with the inclusion of shaders.

Nonetheless, it offers nearly infinite possibilities. You can code and create anything, from a mobile app with React Native to a desktop application with Electron.js. Furthermore, JavaScript provides excellent frameworks and libraries that can be applied in various approaches, such as React, Three, Vue, Meteor, and Astro.
