How to use the LinearFilter function from three

Find comprehensive JavaScript three.LinearFilter code examples handpicked from public code repositorys.

three.LinearFilter is a type of texture filtering used in Three.js that takes the four nearest texels and linearly interpolates between them to determine the pixel color.

How does three.LinearFilter work?

three.LinearFilter is a type of texture filtering method used in three.js, where texels (texture pixels) are interpolated using linear interpolation to determine the color of the pixel at the sampling point, producing a smooth texture image. This filtering method is optimized for textures that are displayed smaller or larger than their actual size.

// create a texture object and load an image
const texture = new THREE.TextureLoader().load("texture.jpg");

// set the magnification filter to linear interpolation
texture.magFilter = THREE.LinearFilter;

In this example, THREE.LinearFilter is assigned to the magFilter property of the texture object to specify that linear interpolation should be used when magnifying the texture.
