# Texture baker

Small texture baker which rasterizes barycentric coordinates to a tensor.
It also implements an interpolation module which can be used to bake attributes to textures then.

## Usage

The baker can quickly bake vertex attributes to the a texture atlas based on the UV coordinates.
It supports baking on the CPU and GPU.

```python

from texture_baker import TextureBaker



mesh = ...

uv = mesh.uv # num_vertex, 2

triangle_idx = mesh.faces # num_faces, 3

vertices = mesh.vertices # num_vertex, 3



tb  = TextureBaker()

# First get the barycentric coordinates

rast = tb.rasterize(

    uv=uv, face_indices=triangle_idx, bake_resolution=1024

)

# Then interpolate vertex attributes

position_bake = tb.interpolate(attr=vertices, rast=rast, face_indices=triangle_idx)

```
