Iris-WebP is a WebP encoder tuned for the human visual system. At equal encode time it produces files 27% smaller than libwebp by CVVDP, at equal quality.

WGSL fragment_depth extension, texture compression unaligned, srgb-linear and display-p3-linear color spaces, snorm10-10-10-2 vertex format, and more.

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.

Real-time GPU texture codecs optimized for mobile and web.

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!
