"Web12 de abr. de 2024 · Let's start with what might at first seem the simplest transformation: normalized device coordinates to pixel space. The transform is. s_x * X_NDC + d_x = X_pixel s_y * Y_NDC + d_y = Y_pixel. A user/programmer does all screen design in NDC. There are three nasty realities of the hardware that NDC hides from us: " - Normalized object coordinate space

[29] proposed Normalized Object Coordinate Space (NOCS) as a category-speciﬁc canonical reference frame for rigid objects. The objects from the same category in NOCS are consistently aligned to a category-level canoni-cal orientation. These objects are further zero-centered and uniformly scaled so that their tight bounding boxes are cen-
