The block contains four applications. Two are identical, . Another . The last

So how about:

TriMeshSample and VboMeshSample - demonstrate all supported primitives and one custom mesh using TriMesh and VboMesh shapes

InstancedSample - demonstrates VBO instancing, a technique which allows you to make a single call to OpenGL with one VBO and draw many instances in GLSL

VtfSample - shows off vertex texture fetching (VTF), a technique which uses texture data to modify geometry.
