The components of the application related to analytical displacement mapping:

• tessrenderer.cpp - The main renderer class for tessellation
• procedural.glsl - Procedural generation of displacement coefficients
• displace.vert - Vertex Shader for displacement mapping
• displace.tesc - Tessellation Control Shader for displacement mapping
• displace.tese - Tessellation Evaluation Shader for displacement mapping
• displace.frag - Fragment Shader for displacement mapping

• Bubblewrap
• Pinhead
• Chocolate bar
• Random

• Interpolated normals
• Approximate normals
• True normals

• Phong shading (see examples above)
• Normal shading (Visualization for all types of normals)
• Approximation Error (Error of approximate errors compared to true normals)

• Screen-based edge length level-of-detail
