Learn the division of labor between MeshFilter and MeshRenderer.
The MeshFilter Component
To give a GameObject a 3D shape, the MeshFilter component is used. MeshFilter holds the reference to which Mesh data the object contains, but does not draw anything on screen itself. It provides this data via the sharedMesh or mesh property.
MeshFilter filter = GetComponent<MeshFilter>();
Mesh modelMesh = filter.sharedMesh;The MeshRenderer Component
The component that takes geometry from MeshFilter and renders it into pixels on screen is MeshRenderer. This component manages material (Material) settings and lighting/shadow behavior. For a 3D model to be visible in a scene, MeshFilter and MeshRenderer work together.
MeshRenderer renderer = GetComponent<MeshRenderer>();
renderer.enabled = true;Practice Check Renderer State
If the renderer.enabled property is true, print Debug.Log("Model ciziliyor");.
Starter code
using System;
public class MeshRenderer
{
public bool enabled = true;
}
public static class Debug
{
public static void Log(object message) => Console.WriteLine(message);
}
public class Program
{
public static void Main()
{
MeshRenderer renderer = new MeshRenderer();
// cizici aktifse ekrana cizim mesajini yazdir
}
}Sample solution
using System;
public class MeshRenderer
{
public bool enabled = true;
}
public static class Debug
{
public static void Log(object message) => Console.WriteLine(message);
}
public class Program
{
public static void Main()
{
MeshRenderer renderer = new MeshRenderer();
if (renderer.enabled)
{
Debug.Log("Model ciziliyor");
}
}
}Expected output
Model ciziliyor
Questions and answers
Review the lesson questions together with their answers. To test yourself, solve the lesson interactively.
1 What is the primary role of the MeshFilter component on a GameObject?
- To change the texture of the material
- To hold the 3D geometry data (Mesh) reference Correct answer
- To convert geometry into pixels and render on screen
- To add physical gravity to the object
Explanation: MeshFilter holds the geometry data in memory; rendering it to the screen is performed by MeshRenderer.
2 Get MeshRenderer Component
MeshRenderer cizici = GetComponent<____>();MeshRenderer cizici = GetComponent<MeshRenderer>();Explanation: To control rendering and material operations, the MeshRenderer component is retrieved.
