Hello :wink:
I am thinking about implementing perspective control on a Houdini camera
(to control the appearance of perspective in the image).

en.wikipedia.org ]
What is the best starting point for this? Should I dive straight into the Houdini HDK?
Any suggestions are welcome.
Thanx!

Hi, For “shifting” you don't need to implement anything - you can simply use the “View -> Screen Window X/Y” controls on the camera. This effectively equals what a “shift lens” does. However to get also “tilt” capabilities one would need a more complex camera model. o.

if you need more control, you can implement it as a Lens Shader, should be pretty straightforward
