Motion Merging

I thought I'd take the time to post a quick overview of the work I did for my thesis (for my M.S. in Computer Science). My thesis work involved working with two independent animation sequences and merging them together in order to attempt to aid in alleviating production schedules. The idea of “motion merging” comes in to place as an alternative to such time inefficient tasks as key framing and graph editing. Merging two independent motions simply means that two animated sequences are supplied and my algorithm takes those sequences and merges them in to one unique sequence.

Several solutions have been discovered towards this "in-betweening" effort including but not limited to key framing, linear interpolation, motion re-targeting, and even manually animating every frame. However, each of these solutions are costly and time consuming. Using quaternions and a form of linear interpolation, a mathematical approach was used to “blend” two independent animated sequences and aid in streamlining this process.

Using the basic guy rig found at The 11 Second Club, I was able to test my algorithm and verify it's success. Following you'll see the videos demonstrating the "in-betweening". The first video uses the basic guy rig where I 'motion merge' the basic guy from a standing position to a sitting position. The second video uses two completely different objects (a cone and a cylinder) where the first object is animated to merge in to the second object's position.

There you have it! Motion merging was a really fun topic to work on. I'll try and post more details on how the algorithm works at a later date.

Behind the Scenes

I have been playing Gears of War 3 lately and this morning as I was re-watching The Incredibles behind the scenes bonus materials from The Incredibles DVD, I was thinking about video games and a potential market that they're missing.

I started thinking about how far along video game story lines have come in the past 10 years. Gears of War 3 is the first game that I've felt truly immersed in the story. Additionally, the graphics and game development going in to games lately is immense. It got me thinking, I really enjoy watching behind the scenes bonus materials on DVDs and these materials are expected in today's market with today's consumers. I'm sure that a great many video game customers would love to have this type of bonus content delivered with every game purchase. Allowing consumers to have this type of access to "bonus content" adds a personal touch to the development and to a lesser degree advertises the studio (and maybe attracts talent to the studio?). 

The Incredibles bonus DVD material is amazing and I highly recommend it to any animation enthusiasts. Hopefully in the future we'll see this type of content delivered with every video game as it is currently delivered with every movie.

Pen and Ink


So the latest assignment was to complete a "Pen and Ink" drawing of a local building. I definitely found this harder than using charcoal at first because of the seemingly final characteristics of pen. However, it was nice on the rendering side when this seemed to go much quicker than charcoal. All in all I think it came out okay and it was a nice change of pace from charcoal.

Jack



Here is my attempt at Jack Nicholson. I wanted to show the progression in the drawing and the picture I used to complete the drawing. I used the grid process in this drawing by applying a grid to both my paper and the picture itself and then working step by step in the transfer process.

I still think that I need to work on my subtle shading but I'm definitely happy with how it turned out.

Female Head Drawing














Here is the latest homework from my foundations course. I think it turned out okay but after looking at things I think I need to re-work some of the proportions. It looks like some length in the face is needed as well as a little more rounding on the top right portion of the head. Thoughts?
