Overview DXTn is a type of image compression whose decompression is hardware-accelerated, which means you can send the same amount of texture information over the bus to the graphics card for a much smaller bandwidth fee since it does not need to be decompressed before the transfer. This makes DDS files using the DXTn compression [...]

L. Spiro Image (.LSI) Format
Overview On low-end devices such as iPhone and Android, small files are essential. On high-end devices with large disc capacity, small files at first seem not to particularly matter, but since the target of L. Spiro Engine is next-generation machines, it is worth assuming that developers will have a substantial amount of resources to put [...]

3D Model Format (Compression)
Overview My goal with all proprietary formats associated with L. Spiro Engine is to be as small as possible as long as the loading times are reasonable. To this end I developed a compression algorithm based on LZW—with modifications for improved security—which decompresses very quickly. However that alone is not enough to achieve the best [...]
