A graphic library and an application for simple curve manipolation

Principles of computer graphics Final project assignment – Michele Segata

The project Develop an application to • Draw and manage different type of curves (control points dragging, use of composite curves, etc…) • Put an image as background to see which curve is best suited • Use a file as a source of points and display the curves using those points

Tools used " Only OpenGL and the graphic library developed for first assignment " Why? For fun and better understanding

First assignment – Brief description " gl_2d_geometry.h " gl_3d_geometry.h " gl_curve.h " gl_material.h " gl_mempool.h " gl_mesh.h

First assignment – Brief description (2) " gl_mouse.h " gl_physic.h " gl_physic_law.h " gl_printf.h " gl_rendering.h " gl_scenegraph.h

First assignment – Brief description (3) " gl_selection.h " gl_tga.h " gl_transformation.h " gl_util.h

First assignment – Few screenshots Convex hull example

First assignment – Few screenshots (a) Face normals (b) Vertex normals (c) Mixed approach Solid pyramid with 3 different normals algorithms

First assignment – Few screenshots Spheres at different resolutions

First assignment – Few screenshots Automatic texture application on sphere
