QTVR - animated object movie of a morphing water sphere- the file size is about 6 mb so it might take some time to load. If you move the cursor inside the movie area, it will become a "hand". You can then click and drag to view the object from any direction.
The object is just a sphere with a water/glasslike shader. I attached a twist deformer and animated the handle to morph the shape - the animation is 6 frames long- it bounces up and down because it is an oscillating forward/backward loop. This movie was created similarly to the QTVR tree (WIP04). A camera was created with a "pan" and "tilt" node which was animated to rotate around the object in 20 degree increments per frame - it then tilts 20 degrees and does another 360 degree pan. Each row and column use 18 frames to "photograph" the 360 view so the total number of frames to create this object would normally be 324 (18x18).
However, since I had 6 frames of animation, I had to photograph it six times - once for each position of the animated object - so the total number of frames required was 1944
(324 x 6). The QTVR object movie has 6 layers - one for each frame or "state". I used an HDR image for relections/image-based lighting - which is an image from a mirror ball that is mapped to a mental ray environment sphere. Initially I had intended on only rendering the object, but since it was already in a virtual environment, I decided to leave it visible to see what it would look like and if it would work with an animated object. I didn't do a shadow pass or tweak any of the perspective attributes of the environment sphere so it's a bit distorted.
The HDR light probe is of The Uffizi Gallery in Florence which I downloaded from Paul Debevec's excellent website http://www.debevec.org/Probes/
The site has several other examples of HDRI images that can be downloaded in different formats and explains everything HDR. |
