Computer Graphics: Modeling

CPSC 524

Fall 2014

Papers - Software and Models



Three-dimensional geometric models are the base data for applications in computer graphics, computer aided design, visualization, multimedia, and other related fields. This course will focus on computerized modeling of discrete (digital) geometry, and in particular polygonal meshes. We will study data structures and algorithms for creating, manipulating, editing and analyzing digital geometry models.


This year's offering will particularly focus on geometry processing for fabrication and specifically emerging non-standard manufacturing processes such as 3D printing, inflatable structures, sketch-based interfaces, and paper or sheet material modeling.


Students are expected to have successfully completed an introductory computer graphics course (e.g. UBC CS 314) or have an equivalent background. An existing knowledge of OpenGL is assumed, although knowledge of a comparable system (such as DirectX) should be sufficient.


More details are provided in the syllabus.

The grade will be based on a combination of: paper presentation, assignments, final project and class participation (no exam). The final grade will be calculated in the following way and will include a large peer feedback component.

      20% - Class participation

      Includes: lecture notes, weekly summaries, classroom participation, and peer feedback

      10% - Assignment 1: Mesh Subdivision due  Sep 26

      15% - Assignment 2: Mesh Simplification , due Oct 24

      15% - Assignment 3: Mesh Deformation , due Nov 14

      15% - Paper presentation

      Sources for papers include proceedings of SIGGRAPH/SIGGRAPH Asia, Symposium on Geometry Processing (SGP) ,Eurographics, and Shape Modelling International (SMI) from recent years (links) .

      All students are expected to read the paper in advance and be ready to ask at least one question

      25% - Final project due Dec 12

·      Includes proposal, due Nov 24 (5%), report + results (15%), presentation Dec 15 2PM (5%).

Software & Models



Software for Mesh Display & Manipulation:

We recommend you use Cartel as the base data-structure/UI support in your assignments and project. It is newly developed local library which comes with no bug-free guarantees but luckily its co-autor Russ is our TA so you can bug him with any problems you encounter.

Other options include Meshlab ( ) and Graphite (

To download models to test your code on check aim@shape. You always want to do intial testing on simple surfaces such as sphere, cube or plane which you can create/export using Graphite.
