Filtering mode for textures. Corresponds to the settings in a texture inspector.

//This script changes the filter mode of your Texture you attach when you press the space key in Play Mode. It switches between Point, Bilinear and Trilinear filter modes.
//Attach this script to a GameObject
//Click on the GameObject and attach a Texture to the My Texture field in the Inspector.
//Apply the Texture to GameObjects (click and drag the Texture onto a GameObject in Editor mode) in your Scene to see it change modes in-game.

using UnityEngine;

public class Example : MonoBehaviour { //Remember to assign a Texture in the Inspector window to ensure this works public Texture m_MyTexture;

void Update() { //Press the space key to switch between Filter Modes if (Input.GetKeyDown(KeyCode.Space)) { //Switch the Texture's Filter Mode m_MyTexture.filterMode = SwitchFilterModes(); //Output the current Filter Mode to the console Debug.Log("Filter mode : " + m_MyTexture.filterMode); } }

//Switch between Filter Modes when the user clicks the Button FilterMode SwitchFilterModes() { //Switch the Filter Mode of the Texture when user clicks the Button switch (m_MyTexture.filterMode) { //If the FilterMode is currently Bilinear, switch it to Point on the Button click case FilterMode.Bilinear: m_MyTexture.filterMode = FilterMode.Point; break;

//If the FilterMode is currently Point, switch it to Trilinear on the Button click case FilterMode.Point: m_MyTexture.filterMode = FilterMode.Trilinear; break;

//If the FilterMode is currently Trilinear, switch it to Bilinear on the Button click case FilterMode.Trilinear: m_MyTexture.filterMode = FilterMode.Bilinear; break; } //Return the new Texture FilterMode return m_MyTexture.filterMode; } }


PointPoint filtering - texture pixels become blocky up close.
BilinearBilinear filtering - texture samples are averaged.
TrilinearTrilinear filtering - texture samples are averaged and also blended between mipmap levels.
