You can't do that with JavaScript! - Espen Sande-Larsen - NDC Porto 2023

Javascript

Discover how JavaScript can be used to create stunning 3D graphics and games, even for high-performance tasks, through a fascinating project on raytracing and experimentation.

Key takeaways

JavaScript is not suitable for high-performance tasks, but it’s great for creating graphics and games.
The speaker’s project was to create a raytracer in JavaScript, and he succeeded after many iterations.
The raytracer uses a algorithm called RayMarching, which involves casting a ray from the camera through the scene and checking for intersections with objects.
The speaker learned a lot of math and physics concepts while working on the project, including vectors, matrices, and complex numbers.
JavaScript has limitations in terms of performance and precision, but it’s still possible to achieve good results with careful optimization.
The speaker also learned about the demos scene, a community of creators who work on demo-competitions, and how it fueled his passion for coding.
Inspiration can come from unexpected places, like a 3D raytracer in JavaScript, and can lead to new adventures and projects.
The speaker also showed some examples of other projects, such as a robot he built and a library of vectors and matrices.
The raytracer’s rendering process involves several steps, including clipping, lighting, and shadowing.
The speaker’s project was a journey of learning and experimentation, and he’s proud of what he accomplished.
JavaScript’s limitations can be overcome with creative thinking and problem-solving.
The speaker encouraged others to explore new ideas and technologies, even if they seem challenging or intimidating.
The raytracer’s results are impressive, with smooth rendering and realistic lighting.
The speaker’s passion for coding and creation is inspiring, and he hopes to continue learning and sharing his experiences.
