Maya live tests WIP

[BloodHo]

I think it looks nice, but maybe shadow is too dark and it doesnt fit to footage. But that is a very good start.
I want to see more :)

Cool! I wish I had maya live to mess around with, tracking is so fun! I love it man, post more when you got it!

[IestynRoberts]

HEy man, that looks pretty awsome. How did you get it to track so good? Im using Ping Pong Balls as markers and it just does'nt want to work, i see that your only using little square paper and it looks pretty meat. What are your secrets dude?

Also, could you tell me how you got the CG and real action plates to blend so nicely? It look really nice man.

Frrking cool.

I really love hand held freestyle stuff - I think its really lacking in the sort of professional work I see around most of the time - with cg incorporated stuff being done with "computery" camera moves. Even worse is when they use super expensive automated camera rigs to make real world cameras follow pre programmed cg camera moves....
anyways, yup more of this natural movement style stuff is needed. It adds tons to the realism and believability of the work - and as i said its frrking cool....

Yep, looks like a pretty solid track. After watching it several times though, it almost looks like the virtual ground plane is slightly below the surface of the desk. Like the shift in perspective of the model and shadow don't match that of the markers. Like I said, only very slight. Could be the fov was a little off?

BLee?? U still about??

[BLee]

Ops. sorry about late reply.
Actually i was testing several shots before. It all turn very badly but for the last test i worked i finally realized that it wasn't the tracking point wrong, it was the Survey (under Solve) that drove me crazy. I was pretty lucky to get that camera match up but i'm still not guarantee to get what I wanted. so for the next few weeks I will do another test and hopefully i can show you guys soon.http://cgtalk.com/images/smilies/smile.gif

Hi,
I've taken few screenshots for my motion tracking work flow.
1. Place motion tracking on each mark. Make sure all is green or yellow. Other wise you need to remove red tracking.

2. Solve > click slove then if below 2.0 is good (solution_RF)

3. Survey > Distance (not sure yet) but I assume this is the distance between each other. Just simply pick 2 point.



4. Plane X is align with your camera angle. you should see a blue grid patch and rotate to match with 2 tracking

5. plane Y same as above but just need to match with Y axis.

6. plane z (ground) http://www.cg-guru.com/temp/temp_upload/motiontutorial/5.jpg

7. Point. Select the center tracking so that when you place your model it will locate at the right place.


8. Go back to Slove hilite solution_rf and click Register. it will simulate your camera angle. It takes some time to correct those survey. I usually create a ground plane and register to test it out.


7.Finally, place your model into this scene. Mine didn’t match up 100% but is a good start at this point.

enjoy it and hopefully my explaination is easy to understand and sorry about my languagehttp://cgtalk.com/images/smilies/smile.gif

Hello BLee. Excellent, thank you very much, that's awsome. There are quite a lot of points i was'nt doing, now it all makes sense where i was going wrong, thanks.
Just one more question if you dont mind. How did u get the CG to blend in so good? What software/effects did u use on the robot?
Thank u very much for the tutorial, i'll go and try it out tonight.

[BLee]

Hello,
I didn't use any effect. Basically just use After effect to composite cg and footage plus just you need to carefull about your shadow casting.
good luck.

[IestynRoberts]

Really? Good god, that's pretty awsome man. I'll give it a whirl.

Thanks again for the tutorial.

Yes, the distance is simply the real-world distance between trackpoints. And I think you may have better results using a single plane constraint with all 4 (or however many) trackpoints that are on a given plane. That way you don't have to worry about the solver misregistering the independant planes. Plus it's a lot easier to work with.

From my experience good survey data is about the most important element of a proper track. Oh, and don't forget to delete the regions where a trackpoint leaves the frame.

[BLee]

Oh, thanks for your tips. :thumbsup:
