[15:09] <AkhIL> and I hope lumiera will use some resolution independend
 measuring for all parameters
[15:09] <cehteh> one can rotate where the node actually sits
[15:09] <AkhIL> like NDC
[15:09] <cehteh> or pass transistions through the renderpipe, make all effects
 transisition aware and apply them at the end
[15:10] <cehteh> the later is better but needs more efforts and some rethinking
[15:10] <cehteh> we will prolly support both in lumiera :)
[15:11] <AkhIL> in renderman's NDC for horizontal image with 4:3 aspect ration
 (-1.33,-1) is lower-left corner and (1.33,1) upper-right
[15:11] <cehteh> ah
[15:11] <AkhIL> so moving to different resolutions and different aspect ratios
 in renderman makes no problems
[15:11] <cehteh> well good point, we will measure in pixel but need to convert
 between them . using a float would be good to address pixels
[15:12] <cehteh> yes
[15:12] <cehteh> what stands NDC for?
[15:13] <AkhIL> Normalized Device Coordinates
[15:14] <cehteh> ok
[15:14] <AkhIL> so from -1 to 1 is a range by smallest image size
[15:15] <cehteh> yes sounds reasonable
[15:15] * cehteh adds a note to the lumiera design docs
[15:15] <cehteh> so far we dont do anything where it matters .. but that will
 come
[15:16] <AkhIL> when you move some logo to (0.8,-0.8) it will stay on screen
 even when you chenge resolution and image aspect ratio
[15:17] <AkhIL> all input images should be scaled to this range (-1,1) by
 smalles side
