Vertices are a list of 3D triangles in the 3D space.
Indices are a list of vertices orders about how the triangles are composed together.
First, a mesh must have vertices and indices, it should be an empty mesh in 3D space.
Create a mesh buffer class object, then add vertices and indices to the mesh buffer.
And also, the material can be created and bound the the mesh buffer too.
A mesh can be pushed with many mesh buffers, every mesh buffer is a drawing call.
Many meshes can compose to a composed mesh.
auto * mesh = new my_3d_mesh; mesh->add_mesh_buffer(mesh_buffer); delete mesh_buffer; mesh_buffer = nullptr; auto * comp_mesh = new comp_mesh; comp_mesh->add_mesh(mesh); delete mesh; mesh = nullptr; delete comp_mesh; com_mesh = nullptr;
