This is a heightmap visualization project. Using the modern OpenGL pipeline (GLSL 4.4)

I'ts an experimental project for glsl 4.x practice.

What it does: -loads a grayscale image using freeimage -from the image, triangulate a mesh and calculate normals for each vertex -uses VBO/VAO to sent the geometry to the GPU -uses shaders for --Geometry shader: calculates the intersection plane --Fragment shader: highlights the level curve and implements a phong lighting
