                            int row)

Adding new VertexBufferObject (VBO) to the VAO

Parameters:

values - Values to fill into the buffer

dimension - Dimension of the values

row - Row to store the buffer in the vao

addVertexBuffer

public void addVertexBuffer(int[] values,
                            int dimension,
                            int row)

Adding new VertexBufferObject (VBO) to the VAO

Parameters:

values - Values to fill into the buffer

dimension - Dimension of the values

row - Row to store the buffer in the vao

addIndexBuffer

public IndexBuffer addIndexBuffer(int[] indices)

Creates new IndexBuffer and adding it to the vao

Parameters:

indices - Indices for the new index buffer

Returns:

IndexBuffer that was created

addInstancedVertexBuffer

public int addInstancedVertexBuffer(int maxInstances,
                                    int dimension,
