About

What is spark?

spark is an advanced 3D Gaussian Splatting renderer specifically designed for integration with THREE.js, allowing developers to create sophisticated 3D renderings within web applications. It boasts features like integration with the THREE.js rendering pipeline to fuse splat and mesh-based objects, ensuring portability across most devices with WebGL2 support. The renderer is optimized for speed, performing well even on low-powered mobile devices. It supports rendering multiple splat objects with correct sorting and handles various major splat file formats including .PLY, .SPZ, .SPLAT, .KSPLAT, and .SOG. Developers can also render multiple viewpoints simultaneously, transform and edit splats for animation, and perform real-time color editing, displacement, and skeletal animation. A shader graph system allows for dynamic creation and editing of splats on the GPU.

Best used for

Ideal for ux designers and developers who need to integrate advanced 3D Gaussian Splatting into THREE.js web applications, create dynamic 3D animations, and render complex scenes efficiently. Especially valuable for projects requiring high performance and portability across various devices.

FAQs

What are the primary 3D splat file formats supported by spark?

spark supports a variety of major 3D splat file formats, including .PLY (with compressed options), .SPZ, .SPLAT, .KSPLAT, and .SOG. This broad compatibility allows for flexibility in importing and rendering different types of 3D Gaussian Splatting data within your THREE.js projects.

Can spark be used for real-time animation and editing of 3D splats?

Yes, spark is designed for fully dynamic use, allowing each splat to be transformed and edited for animation purposes. It supports real-time splat color editing, displacement, and skeletal animation, providing powerful capabilities for interactive 3D experiences within web applications.

What are the system requirements for running spark, particularly regarding WebGL2?

spark is highly portable and targets 98%+ WebGL2 support, meaning it should work across almost all modern devices that support WebGL2. This broad compatibility ensures that applications built with spark can reach a wide audience without significant hardware limitations.
