Texture.to_grayscale

Texture.to_grayscale() → Texture

Convert this texture as a single component (grayscale) texture.

Returns:

pyvista.Texture

Texture converted to grayscale. If already grayscale, the original texture itself is returned.

Notes

The transparency channel (if available) will be dropped.

Follows the CCIR 601 luma calculation equation of Y = 0.299*R + 0.587*G + 0.114*B.
