How hard would it be to take an image of an object (in this case of a predefined object), and develop an algorithm to cut just that object out of a photo with a background of varying complexity. Further to this, a photo's object (say a house, car, dog - but always of one type) would need to be transformed into a 3d render. I know there ...
What would be the best way to implement, store, and render spherical worlds, such as the ones in spore or infinity but without the in-between stages of spore, and multiple worlds ala infinity universe. Make no assumptions on how the planet itself is generated or its size/scale. ...
I'm starting to learn about 3D rendering and I've been making good progress. I've picked up a lot regarding matrices and the general operations that can be performed on them. One thing I'm still not quite following is OpenGL's use of matrices. I see this (and things like it) quite a lot: x y z n ------- 1 0 0 0 0 1 0 0 0 0 1 0 0 0 0 ...
