tilt shift esque

[dmn]

would be nice.
I don't know if it is essential in indigo that the vanishing point be in the center of the rendering, but say I want to render an image that is 80% sky and 20% ground, just catching the top of the line of trees in front of me, but without any distortion of vertical lines.
In real photography you would use a tilt shift to do this ($2000, yeah ok there are lomo methods). Right now I have to render 1600 Wx 1600 H and then crop it to 1600:900. Kind of a waste right, like buying a field camera($10000) and cropping the(also expensive) negative?

I think this could be controlled in the xml either by specifying dx and dy for the vanishing point from a corner of the rendering, or by specifying a large image and then also specifying a top-left and bottom-right corner to crop to. I like the latter method because you could also use it to preview a region of your image.

Example of method 1:

Code: Select all

<renderer_settings>
		<width>1600</width>
		<height>900</height>
		<vpx>600</vpx>
		<vpy>180</vpy>
		...

or method 2:

Code: Select all

<renderer_settings>
		<width>1600</width>
		<height>900</height>
		<tlx>0</tlx>
		<tly>0</tly>
		<brx>1400</brx>
		<bry>720</bry>
		...

and possibly with method 2 you only need to input one corner, maybe just x or y, and the other values will default to the usual value.
It would be nice if this could reduce render time.
Ok, enough imaginary coding for one night.

I think the most elegant and robust realization for this in indigo would be region rendering. That would exactly do what a shift lens does.

Also Ono has mentioned that he will code region rendering in the near future since it is not that much work.

what would be the difference, from what I described?

[CTZn]

I don't see any difference, you find another application of the region rendering, originally requested by me© ook ook

[dmn]

Thanks CTZn, I had been wondering if someone had put this up as a request, but you can't search this forum by title only.
I think CTZn region render© would be very useful.

ook ook !
