The AddTriangleIndex method is used to add a triangle to the vertex buffer by specifying three vertex indices. This method is essential for defining the geometry of a 3D model by connecting vertices to form a triangle, which is a fundamental building block in 3D graphics.
To use the AddTriangleIndex method, you need to have an instance of the VertexBuffer class. Call this method with three integer parameters, each representing the index of a vertex in the vertex buffer. These indices should correspond to the vertices that form the triangle.
// Create a new VertexBuffer instance VertexBuffer vertexBuffer = new VertexBuffer(); // Initialize the vertex buffer with indexing enabled vertexBuffer.Init(true); // Add vertices to the buffer (not shown here) // vertexBuffer.Add(new Vertex(...)); // Add a triangle using vertex indices vertexBuffer.AddTriangleIndex(0, 1, 2); // This will create a triangle using the vertices at indices 0, 1, and 2.
