## What it is
A C++ demo application implementing the 'Practical Real-Time Hex-Tiling' technique for hiding texture repetition in real-time graphics. It provides shader utility functions (hextiling.h) for seamless hex-tiled texture blending, including a world-space variant for large levels.

## Use cases
- hide texture repetition on large surfaces in real-time rendering
- implement hex-tiling shaders for tiled textures
- apply planar or triplanar hex-tiling projection on large game levels
- evaluate hex-tiling with rotated tiles and normal maps
- learn the hex-tiling technique from the JCGT paper

## When to choose
- you need to reduce visible tiling repetition of textures in a real-time renderer
- you want a reference implementation of practical real-time hex-tiling
- you need world-space hex-tiling with fractional precision far from origin

## When to avoid
- you need histogram-preserving hex-tiling with precomputed transform textures
- you need a production-ready engine feature rather than a demo
- your project does not use programmable shaders or real-time graphics
