Research on reducing the sense of repetition through tiling

Abstract

In previous game development, when applying textures to such vast terrain, A technique called tiling has been used to lay out a single seamless texture like a tile. However, the wider the area on which tiling is applied, the more the repeating pattern becomes noticeable. Therefore, the goal of this research was to improve the repeating feel of patterns and the lines that are visible at a distance. We focused on a method called texture blending, which combines two textures to create a natural look. Then, blend the tiled surfaces using Perlin noise as a mask image to create the pattern of the two textures. By making it appear sparsely, the repetitive feel of the pattern was reduced. In addition, for distant views, the textures pasted on tiles are randomly rotated for each tile, eliminating texture boundaries that are noticeable in distant views. Made it difficult to see. These processes made it possible to improve the sense of repetition that had been a problem with the tiling method.
