The AddIndex method is used to add an index to the VertexBuffer. This method is essential when you are working with indexed drawing, where you define the order in which vertices are processed.
The AddIndex method is used to add an index to the VertexBuffer. This method is essential when you are working with indexed drawing, where you define the order in which vertices are processed.
To use the AddIndex method, you need to have an instance of the VertexBuffer class. Call the method with an integer parameter that represents the index you want to add to the buffer.
// Create a new VertexBuffer instance VertexBuffer vertexBuffer = new VertexBuffer(); // Initialize the vertex buffer with indexing enabled vertexBuffer.Init(true); // Add vertices to the buffer vertexBuffer.Add(new Vertex(/* vertex data */)); vertexBuffer.Add(new Vertex(/* vertex data */)); vertexBuffer.Add(new Vertex(/* vertex data */)); // Add indices to define the order of vertices vertexBuffer.AddIndex(0); vertexBuffer.AddIndex(1); vertexBuffer.AddIndex(2); // The indices added will define a triangle using the first three vertices added.
