2 Homogeneous coordinates Recall that an affine function is of the form f^x) Mx + t for a matrix M and vector t. Homogeneous coordinates are frequently used to represent affine functions in robotics and 3D graphics. We define the function H by and if f-x) Mxtt where then C0 a. Some vectors are valid homogeneous representations of vectors, and some are not. Explain how to tell if some vector y-0 is the homogeneous representation of some other vector -y...
#3 Only In the following 4, let V be a vector space, and assume B- [bi,..., bn^ is a basis for V. These 4 problems, taken together, give a complete argument that the coordinate mapping Фв : V → Rn defined by sending a vector v E V to its coordinate vector [v]в є Rn is an isomorphism between V and Rn. In other words, Фв : V-> Rn is a well- defined linear transformation that is one-to-one and onto....
