Vertex shader which is used to verify the proper allocation of normals in the uv wrapped texture of a 3d model.
Contains geometry shaders along with normals to check for the correct disposition of the normals in a texture wrapped object. Contains 3 shaders: 1.vertex shader -initialized the variables ,interface block and passes the necessary arguments after NDC normalization 2.geometry shader- spawns adjacent normal lines in line_strip form alon each of the 3 vertices of a raster triangle.Passes the attributes to pixel shader for coloring.If an object does not have the normals then it throws error and rendering stops 3. fragment shader-Colorizes the pixels of the normals The shader code is written in GLSL and uses #version 330 core.

The folder contains the vertex,geometry and fragment shaders written in GLSL code to determine whether the normals are present in a texture wrapped object and also has attributes for scaling the length of the normals drawn during rendering.
If normals are not present in the wrapped texture then code throws exception and rendering stops.
This can also be used to generate fur-like shader which can be used over the normal uv wrapped objects for better effects.
