virtual forest

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

f u t u r e a i m • 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
