Alpha Map
Explore how to use alpha maps in Three.js to manage transparency in 3D textures. Understand how black and white values on an alpha map control opacity, set material properties like transparency and side rendering, and apply texture properties such as wrapping and repeating to enhance 3D models.

Alpha map to create transparent models
With the alpha map, we can use a texture to change the transparency of parts of the model. An alpha map is a way to control the opacity of the surface. If the value of the map is black, that part of the model will be fully transparent, and if it is white, it will be fully opaque. The following screenshot shows the result of the alpha map:
