virtual forest • Virtual Forest initiated as our group project for the course CmpE 460: Introduction to Computer Graphics (Ali Vahit Şahiner) in Boğaziçi University CMPE Department.

our purpose was • To create a plant modelling tool, which is easy and fun to use. • Better interface allows more user creativity to be reflected as an interaction.

related areas • Design and art – Sense of aesthetics

• Science – Botany – Physical structure of plants

• Technology – Programming language: C++ – Graphics Lib: OpenGL and GLUT

possible applications • Used for creating virtual worlds – Computer games – 3D interfaces – Artificial life

examples: half life 2

examples: half life 2

specifications • A modelling tool • An animation engine • Three different species of imaginary plants

first steps

modelling tool • Our modelling tool uses its own file formats: Plant Description (PD) and Scene Description (SD) • This makes the program a closed system, like an experiment • This is because it is a course project

modelling tool • A Plant Description is composed of – Primitive elements like branch, leaf, flower etc.

– These elements are organized in a tree structure – Every element keeps its position, rotation and scale.

All relative to its parent

animation engine • Rotating camera around the plant while modelling • Putting your plants in the scenery • Walking through your scenery • Two scenery modes: Morning View and Dawn View

possible future work • Exporting/importing filetypes like 3DS, WRL etc.

• Real time animations like swaying in the wind • Shading • Raytracing

current project: Face Edit

Face Edit • Face Edit is our project for CMPE 535: Computer Graphics • Part of a general study on facial animation • Has a similar, easy-to-use interface just like Virtual Forest

Face Edit: specifications • A generic tool for editing 3D faces • Focused on the geometric model: vertices, edges and surfaces • Reads and writes in the portable, standard VRML format

future aim • Gradually collect all the ideas and experiences that we gain, and use them in larger projects, like a game • Be involved in other enjoyable and yet serious CG projects, on any level
