About

Python texture sampling, processing and synthesis library for PyTorch-involved projects.

This library is a hodgepodge of tangentially-related procedures useful for sampling, creating and modifying various kinds of textures. This is primarily intended for batched or unbatched PyTorch image tensors. This library provides:

• image resampling/rescaling, cropping and padding

• tiling

  • split images into tiles
  • merge tiles back into images
  • seamlessly stitch textures with color or vector data for mutual tiling or self-tiling

• texture atlases

  • pack images into texture atlases
  • sample images from texture atlases
  • generate tiling masks from texture atlases

• computing and rendering 2D signed distance fields

• computing and approximating surface geometry

  • normals to height
  • height to normals
  • height/normals to curvature

• approximating ambient occlusion and bent normals

• blending multiple normal maps

• pseudo-random number generation

• generating tiling spatial-domain noise

• generating spectral-domain noise

• warping image coordinates

• transforming 1D and 2D images to and from Haar wavelet coefficients

• (experimental) backend-agnostic 1D/2D/3D textures for Taichi (if installed with Taichi optional dependency)

  • load from and save to the filesystem
  • convert textures to and from PyTorch tensors
  • sample textures with lower or higher-order interpolation/approximation

Getting started

• Recommended: set up a clean Python environment
• Install PyTorch as instructed here
• Run pip install tinytex
• Run ttex-setup
