Creating Meshes

Meshes are flat 3D planes which give them a 2 dimensional look. The meshes can be seen from the front and back, but the sides are too narrow to show anything. This gives the meshes the appearance of a flat 2D plane while still having 3 dimensions. This third dimension, along with the ability to be affected by a camera is what separates meshes from GUI elements. Meshes are components which are attached to actors. When creating a large amount of the same mesh instanced meshes can be used which greatly help with performance.

Creating a Mesh Quad

TestScene.java

@Override
public void OnBegin() {
   Actor myActor = new Actor("myActor"); // Creates new actor called my actor on this scene, takes in identifier string
   
  MeshQuad myQuad = new MeshQuad(
             "testMesh", // Unique Identifier
             new Transform(), // Transform
             ShaderLib.Shader_2DQuad, // Shader
             "Image/blankTexture.png", // Texture
             new Vector4f(1f), // Color
             cam.GetCamera()); // Camera
   myActor.AddComponent(myQuad );
}

Creating an Instanced Mesh Quad

TestScene.java

@Override
public void OnBegin() {
   Actor myActor = new Actor("myActor"); // Creates new actor called my actor on this scene, takes in identifier string
  
  MeshInstancedQuad myInstancedQuad = new MeshInstancedQuad("meshInstanced", // Unique identifier
		new Transform(), // Transform
		ShaderLib.Shader_2DQuadInstanced, // Shader
		"Images/blankTexture.png", // Texture
		new Vector4f(1f), // Color
		20, // Amount to render
		new Vector3f(0,0,0), // Offset of each item rendered
		cam.GetCamera());// Camera
   myActor.AddComponent(myInstancedQuad);
