Project 1 Guidelines

ARTD 471 | Fall 2010

PROJECT 1 GUIDELINES
“Augmenting the Absence”

Title: Augmenting the Absence

Project Overview: Instead of taking the usual tack of manipulating 3D Imaging to show an augmentation of reality (super heroes, special effects, fantasy landscapes, etc), the first project will be about revealing the ABSENCE of something real.  Allow your attentive gaze to fall upon a conceptually intriguing issue and use the 3D visualization toolset to reveal either the underpinnings of the issue or the vulnerability of the said issue when a key element is missing.

It is suggested that you choose one of the following themes to tackle:

·      Power Figures

·      Larger organizations (corporations, universities, political machines)

·      Embodied Energy

·      Food item – (biology, politics, chemistry, anatomy)

Why this approach? The purpose of the first project is get you as creators to use this powerful tool of 3D imaging in new and unexpected ways. Creation instead of emulation is the name of the idea – especially allow the IDEA to supersede the product.  Let metaphor play a role in this project instead of falling back on the easier diagrammatic and literal approach to 3D.

Images/artworks/references will be shown in class.

I know little about keyed particles but there is ample documentation online. Just another arrow in our quivers, or whatever.

Toon Shading

Though we haven't gone over this in class, Blender does have a TOON SHADER which will allow you to get closer to a cell shaded look in your renders. There are many resources on the web, but I wanted to show you a sample image and example .blend file.

The file can be downloaded here: http://uoregon.edu/~park/472/Models/toon.blend

Note: toon shader options are availabe under the Shaders tab in the Shader Panel. Ambient occlusion IS on in this file. Edges are on (black contour lines), an option that can be found under the Edges button i the Scene Panel (where you change render settings).

3D Game Engine Options

Blender has an inline 3D game engine. To get started, check out this link:

Iris Texture Resource

This is a link to the original Blender Nation article, make note of the portion where the owner of these photographs requests an email before use. Please do so, I've used Jon's iris photos before and he only cares to know about the project and to get a link to it's completion. Follow the link on the BN page to the textures, enjoy!

Linked Libraries (better than appending for group projects)

Here is the process of linking libraries/groups/armatures to one another in Blender. In many ways this is superior to APPENDING because it preserves weight painting and armatures. On the flipside, this process is more tedious and requires some setup:

I prefer the following method:
1) In master file, set the PATHS in User Preferences to 'relative'
2) group everything you want in the master file by selecting them in object mode and hitting CTRL+G (select Add to New Group). You can rename the group in the Objects Panel (F7).
3) In the New Blender file that you want to link stuff into, go to File>Append/Link. Toggle the LINK button (as opposed to the APPEND button) and then click into the master .blend file. Go into the 'Groups' directory and choose your group.
4) Though it appears that nothing has happened, something has been added to your scene. In object mode hit the space bar and choose ADD>GROUP>your group name
5) Now you see a linked uneditable replica of the master group.
6) To allow for editability select the group and hit CTRL+ALT+P to make a proxy (similar to an Instance in Flash).

A slightly different method can be read about here:

Audio Analysis - WAV file to IPO Curve

Audio Analysis Script:
This script will read a .wav file and map the amplitude to several types of IPO curves. It’s a great tool for synchronizing certain effects (like thunder and lighting, explosions etc) in your animation with the audio.

Quality Tutorials on Animation and Rigging Setups in Blender

Below is the link to the "ManCandy FAQ" set of videos. Mancandy is a fully (thoroughly) rigged character that has been made available as a learning tool. Though the rig itself may be more advanced that what a beginner animator would normally need, there is MUCH TO LEARN from the setup.

To make things even better, the creator of the rig created an extensive training DVD called the 'ManCandy FAQ'. This is available for purchase, but also available for free via YouTube HD (hurray for the open-source spirit). The video playlist of the 38 exceptional video tutorials is here:
http://www.youtube.com/watch?v=JEiJJ1nMI4k&feature=PlayList&p=5643529BBE9522A1&playnext_from=PL&playnext=1&index=1

The full model (and rig) is available for download here:  http://freefac.org/mancandy/mancandy_2.48.blend

If you are at all interested in character animation I HIGHLY suggest that you download the rig, explore its setup and watch the accompanying tutorial videos. Good luck and have fun!

Siggraph Modeling Video

MatchMoving - Icarus (and optionally Voodoo)

Week 3: Match-Moving
We will be looking at the process of motion tracking (AKA, Match-Moving). The process of match-moving is a way to  process raw video taken with a camcorder, and retrieve information about the position/rotation/zoom/tilt of the camera so we can emulate those EXACT movements in 3D space. The end effect is to be able to seamlessly composite 2D video with 3D models. Here are some useful links, notes and thoughts about the process:
---------------------------------------------------
Icarus Program Download and Support:
http://www.colinlevy.com/tuts/IcarusTutorials/Icarus.php
(please note that this software is a personal edition, not meant for commercial work and is no longer supported by the software engineers because the company was bought by a larger software entity. The commercial version went on to become PFTrack).

There are a number of useful video tutorials on the above site that will get you started.

Notes about using/shooting video:

• Using a camera to pan/tilt/zoom is easier for the program to recognize and calibrate. Use a tripod when possible.
• We will experiment with shooting in HD and down-sampling a copy video to DV quality for the matchMoving calbration. In the final render we will reuse the HD version. I am using HD video, compressed down in Adobe Media Encoder to two files: a 480P version and a 1080P version (.MP4).

Notes about Calibration:

• If there are moving elements in the video that you want Icarus to ignore, you can mask out that element. Go to TRACKING>NEW MATTE and create a new matte by click points to make an N-gon shape. You can go to a new point in time and move those same points and Icarus will auto keyframe between the two times.
• There are two kinds of tracking: User Feature Tracking (manual) and Auto Tracking. Generally speaking, auto-tracking works better for more organic shapes that lack distinct features or hard angles, and it is a lot slower to track. User Feature tracking is faster and is better for angular features in video.
• When Auto Tracking, start with TRACKING>TRACKING PARAMETERS. Setting the 'Num Auto Features' determines accurace (more featuers = more accurate, more wait time). Same goes for 'BackTracking' which tracks the video backwards after it is done tracking forwards.  When you are ready, go to TRACKING>AUTO-TRACK and let the program do its thing (this will take a while...good time to make coffee).
• If there are areas of video that show clearly defined Y or X axes, it is a good idea to Go to the COORDINATE FRAME icon in the left-hand panel and draw two parallel lines for the Absolute X and Y axes. If you do this, then go to CAMERA>ESTIMATE FOCAL LENGTH to improve accuracy.
• If the Auto-Tracking feature doesn't do it already, you need to calibrate the video (after it has found the tracking points). CAMERA>CALIBRATE.
• When it is done, you should see a ground plane and a blue ball in your video...if not go to VIEW>GROUND PLANE. Choose a green tracking point that you want to be the main area in 3D space where you animation will take place, right click on that point and choose 'SET AS ORIGIN'. This will become the 0,0,0 origin in Blender. If the grid that appears look off axis, click on the 'Coordinate Frame' icon in the left hand panel and left mouse drag til the ground plane looks better.

Notes about Getting 3D data into Blender:
There are two steps in getting the Icarus camera data:

1. Export 3D Data by going to PROJECT>EXPORT 3D MOTION from Icarus. For the format type, choose 'Human Readable (.txt)'
   
2. From Blender you need to open the Icarus import Python script (called 'ICARUS_import241.py'). If you are on your own machine, you probably want to copy this file to your Blender python script directory. But if you are on a lab machine, simple go to the TEXT EDITOR window type in blender, and open the python script from there. Then go to TEXT>RUN PYTHON SCRIPT. It should then copy the 3D camera data from Icarus to your camera. You may need to select your camera prior to doing this.

--------------------------------
If you want to look into an alternate program, check out Voodoo.
Here is a pretty good looking tutorial:

If you fall in love with this process and want to take it to the next level, consider purchasing PFTrack 5, higher end, more polished, and roughly $150 for an academic license.
