Encoding textures with tile shaders: on most iPhones, as fast as not encoding at all.

Spark 1.4 adds real-time BC6H and ASTC HDR texture compression, BC1 Ultra, BC7 NRM, ASTC 5×5, and broader GPU compatibility.

No pages of installation guides. No Gigabytes to download and install. Just unzip, run and focus on performance issues. It Just Works™.

You would think that loading images in the browser is a solved problem. After all, websites are basically composed of text and images. Turns out that loading images from JavaScript to use in WebGL/...

The Apple Lossy compression format was introduced in the A15 and M2 chipsets (which share the same GPU generation) and it enables sampling and rendering to textures with a 1:2 compression ratio. The f...

In my previous post Writing to Compressed Textures in Metal, I showed how Metal heaps can be used to alias buffers and textures to inspect their actual memory layout. Something that caught my attentio...

Writing to Compressed Textures in Metal using heap aliasing.

One of the things I've always lamented about hardware image formats is the slow pace of innovation. Developers were usually unwilling to ship textures in a new format unless that format was widely ava...

I'm excited to announce spark.js 0.1, now with WebGL support!

One of the advantages of runtime texture compression is that mipmaps can also be computed at runtime and do not need to be transmitted. In contrast, offline codecs must precompute mipmaps so they can ...

In recent years, neural networks have started to find their way into many areas of rendering. While antialiasing and upscaling are probably the most well‑known uses, they’re far from the only ones—…

A GLTF viewer that ships textures as compact WebP or AVIF, then transcodes them to GPU-compressed formats in the browser. Small downloads, efficient VRAM. Spark.js handles the conversion so you get th...
