Subject : doing something different with Custom FX Operators
Hey guys,

I'm trying to do something a little different here so bear with me... I'm
doing a plug-in that will analyze 2 image sequences and the scene camera's
transform to output 1 image. So 2 image sequences + 1 animated Camera = 1
single output image.

First, I need to figure out how to pass scene information to the custom FX
operator. In my case, the FX operator needs to know the camera's
transformation matrix and I also want to use XSI classes like CTransform to
do some calculation inside my custom FX operator. How do I do that? How can
I make the link?

Second, I need to analyze the whole sequence before I can create my final
output image. So instead of outputting to an image format, can I output to a
custom data structure like a userDataBlob or something similar that would
then be used to create the final image?

Any pointers or suggestions you guys can give me could end up being very
useful. So please let me know how you would approach the issue. Thanks.
