I am working on a live wallpaper with Libgdx . I am wondering if I can give neon glow to my textures , at runtime . Is this possible? If yes can anybody give me any pointers?
Theoretically, sure. Two approaches come to mind:
- Write a shader
- Fake it
For faking it, you could draw four copies of the sprite (offsetting horizontally and vertically by 1px above/below/right/left of the main image) and tinting that to your neon colour.
I haven't tried it, so your mileage may vary.
