[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
