Animator Help Session November 20 th, 2002,

Agenda Introduction Curve implementation - What are all those vectors? - Where should I put things? Particle System - What is it? - What should I implement? Animation - What should I do? - How to use Adobe Primere?

Introduction How to integrate with my model? Modeler View vs. Curves View Graph Widget Interface

Curve Implementation What are all those vectors? In any specific curveEvaluator class ptvCtrlPts: a collection of control points that you specify in the curve editor ptvEvaluatedCurvePts: a collection of evaluated curve points that you return from the function calculated using the curve type’s formulas fAniLength: maximum time that a curve is defined bWrap: a flag indicating whether or not the curve should be wrapped

Curve Implementation Where should I put things? Create - Bezier - B-spline - Catmull-Rom In GraphWidget class

Curve Implementation Some more stuff Wrapping Curve Going Back to time Mutable?!

Particle System What is it? Particle Objects Forces An engine for simulating the effect of the forces

Particle System What should I implement? Constructor Destructor Simulation functions - drawParticles() - startSimulation() - computeForcesAndUpdateParticles() - stopSimulation() Particle and force class… maybe?

Particle System Some more stuff World coordinate of particles?? Euler Method Hooking up your particle System

Animation What should I do? Editing Curves

Working with Adobe Premiere (A sub-help-session by das Steve)

What is Premiere, and where do I get it? Industry standard digital video editing application. Can use it in the Graphics Lab (v5.1 full version on all machines) Or can download a time-bombed, fully functional demo from Adobe (v6.5):

Why do I care about Premiere? You’ll probably want to take the raw frames spewed out by your animator program and turn it into a movie... Adding effects! –Editing your movies (transitions) –Adding sound effects or music... And if nothing else, pretend to care and make me feel good?

What I’ll show you Premiere interface Making a movie from pictures Saving your movie –Compressed vs. uncompressed Adding sound effects! Making edits/transitions... All in 10 minutes or less!

Important Notes DO NOT FORGET to go to File->Preferences->General / Still Image and set the Still Image Duration to 1 frame. –Otherwise, your movie will be veeery boring. To speed things up, right click on a clip and choose speed. Change to x (>100) %. You may need to do this to fit the time limit. To add a title page or credits, make the picture in Photoshop first and import it in. (Text is a pain in Premiere) To export your final copy, make sure to change your settings to: –Video Compression: MPEG V2 (small, easily playable files) –Audio Compression: your choice, but uncompressed is fine (and will work with MPEG)
