showing how to do a 3d card system in nuke using card3d. Here are some notes to help you guys:
Recap, Things to Remember
1.) use card 3d instead of card where you can
2.) The uniform scale of the card expression is:
.49152*-translate.z
3.) use an axis node to control the cameras pivot
4.) premult the depth from the card3d by the alpha
5.) set merges to "also merge" the depth channel
6.) us the focal plane setup in the zblur and animate the focus plane,
depth of field and maximum for a shift focus
----------------------------------------------------------------------------------------------------
Uniform Scale of Card or Card3d:
Expression:
(Camera1.haperture/Camera1.focal)*-translate.z
-----------------------------------------------
The Default Settings of a camera in Nuke are always the same,
even when the project settings global format changes.
The cameras h-aperture and focal length are always:
h-aperture: 24.576
focal lenght: 50
--------------------------------------------------------------------
The first part of the equation gets simplified by us since it is
always the default and only changes if we import the camera
or change it ourselves. Therefore the new equation is:
0.49152*-translate.z
