Making a Hemi-cubic 3D Camera in Maya
Page 1 | Page 2 | Page 3 | Page 4 | Page 5Step 5
Go to HotBox>Recent Commands>performCameraOnly0 (you get to the HotBox by holding down the space bar.) This will create another camera. You can also do this by hitting the "g" key (repeat last command).
Name this camera Rcam for RIGHT camera and set the Rotate Y to -90 in the channel box as shown. Notice that the Rcam sits on the left of the rig but it FACES RIGHT.
Step 6
Repeat step 5 two more times making Lcam (LEFT camera) with rotate Y set to 90 and Bcam (BACK camera) with rotate Y set to 180.
You will now have 4 cameras, FRONT, LEFT, RIGHT, and BACK, sitting at the very center of the scene, with their viewpoints (mentioned in step 3) exactly on the same spot.
It is very important not to move or rotate any parts of the rig (other than the correct rotations for the different cameras.) Check to make sure the translate x,y,z and rotate x,z are all zero, and that the rotate y are as instructed above.
Step 7
Repeat the camera command one more time, making the Tcam (TOP). This one needs to be rotated 90 degrees on the X (rather than Y as all the others).
Very Important... the top camera must be positioned with the bottom of the camera pointed to the front. When you look through the cameras, the view will be upright in all four F,L,R B, and the view in the Top camera will be bottom of image touching top of front image. The stitcher will not perform properly if any camera is turned any other way. (see step 21 on page 5.)
If you have correctly followed the steps so far your top camera will be correctly positioned.
Step 8
If you now open
Window>hypergraph
you will see 5 separate camera nodes.
Step9
Drag select all 5 nodes in the hypergraph window and hit ctrl-g to group them. Name this group node camRig in the channel box.
