Re: Camera Mapping vs Pyramid mapping ?

2006-02-27 Thread Matthias Kappenberg
Hi Gary,

was on topic long time ago with pjotr akkurra, reproducing a LW
scene. the big difference is, that the pyramid can be used, even if the
camera is looking from another point.
Think about the following, you have one photo from a scene, and then
you like to move your camera a little bit, in this case you need the pyramid 
mapping
(projected from your's photo position).
If you use this one shot as camera mapping, no camera movement is visible.

Subject: Camera Mapping vs Pyramid mapping ?


 Hi List :
 
   I've used the RS Camera Mapping tool and found it to be
 really awesome for combining CGI and pre-rendered animations
 or video . Never used the 'Pyramid Mapping' technique and
 am wondering what the Pro's and Con's of the 2 methods are ?
 
Seems the 2 methods are very similiar but there obviously
 must be a slight difference in exactly how and where each
 method should be used .
 
  RS has a cool little mpeg in it's gallery showing the use of
 Pyr-mapping with video but am wondering why 'Camera Mapping'
 wasn't used in this case ?

 Thanks In Advance .

Hi Matthias :

   Yes , of course , but what I was asking (that Vesa replied to in
the forum thankfully) was why , in that animation example on the RS
site , was camera mapping not used , since it was an example of a
Synth-Eyes camera import script and a background video (not a still) .

  That is to say , since the camera is going to be locked to the
script , and not looking around at all , the very quick and easy
camera mapping method could have been used for every frame .

  Vesa replied yes , it could have . I was scratching my head
thinking that maybe I didn't understand something about camera-
mapping with RS , but I think RS was just trying to show another
method in that anim .

  Anyway , it was a good forum thread and I think a new tool will
be added to V6 as a result of it .

  Also , I am almost finished my elaborate tutorial on RS Camera
Mapping/Gi/HDRI and should be done with it tonight , if I'm lucky .

Thanks for your reply . Where have you been lately ? I thought
maybe you fell down the same hole Frank Dodd and all the others
fell down grin .
