Document Summary
I"ll ask (cid:455)ou (cid:449)hat the (cid:862)fu(cid:374)da(cid:373)e(cid:374)tal pro(cid:271)le(cid:373) of seei(cid:374)g depth(cid:863) is. Shape from shading: two pictures are the same, light sources are shining down onto the scene; makes look like there are bumps or troughs. Linear perspective: lines are parallel in a 3d world, and will appear to converge in a two dimensional image. Relative height: objects at different distances from the viewer will form images at different heights, objects further away will be seen as higher. Relative size: comparison in size of two items without knowing the absolute size of either one. Occlusion: cue to depth order, one object obstructs (is in front of another object) Aerial perspective: more light is scattered when we look through more atmosphere, thus more distant objects appear fainter, bluer and less distinct. Texture gradients: items of the same size form smaller images when they are farther away. I"ll ask (cid:455)ou (cid:449)hat the depth (cid:272)ue (cid:862)a(cid:272)(cid:272)o(cid:373)(cid:373)odatio(cid:374)(cid:863) is (cid:271)ased o(cid:374).
