Hey everyone, yesterday i was toying around to achieve stereoscopic rendering inside Blender (why i posted in “animation” in just a sec). I’ll briefly explain what i did to illustrate the problem i have (pls read carefully its quite hard to explain for me).
- Duplicated camera, moved it a little bit on the side, so to have a left eye camera and a right eye camera.
- Made a second scene inside my Blend file, to wich i linked all objects.
- Assigned the left camera to one scene and the right camera to the identicall second scene.
- Made a simple node setup to make both scene render one on the other, but one only with red channel and the other with both blue and green, this way obtaining the usual red/greenish anaglyph combination.
Now, all of this is nice and works fine, but here comes my problem. Camera’s need to always be one side the other and also point at the same point.
- I made two empties, one to control the movement of both cameras and the other controlling the point to wich the cameras look.
- I made the control empty as a parent, then the 2 cameras as sons, and also the “point to” empty as another son of the first empty. I assigned both cameras to llok at the “point to” emtpy.
Now i could move everything by moving the first empty, and point both “eyes” by moving the second empty. It works fine if you point this litle sistem just ahead of itself, but when you want o point up vertically or rotate the control emtpy, the cameras will stop being alligned horizontally and twist themselves.They still are dependant from the control empty and still look at the “look to” empty, but they cease being one at the exact side of the other (figure a binocular, both lenses are pone side the other at all times, but you twist their relative positions…here the same happens but what is needed is quite the opposite.
Does anyone have a nice tip to solve this issue? I will try to explain better if the way i explained was to complicated. :spin:
