This is a Computer Graphics Question on Linear Transformation. Please show all steps of the derivation. Derive |4x4| rotation matrix for a 3D point rotation across the Y-axis and the center of rotation is (a, b, c).
This problem is on Computer Graphics and is based on the topic 'Perspective Projection'. Please provide a step-by-step solution to the problem and explain the steps. The solution must include the General purpose perspective projection matrix. Question: Let a 3D point (423, -423, 423) be projected on a projection plane. Given that the center of the projection plane is (0.0, 0.0, -423.0) and the coordinate of the COP is (4, 2, 3). Determine the coordinate of that 3D point on the projection plane using a general purpose perspective projection matrix.

The main reason why matrix multiplication is defined in a somewhat tricky way is to make matrices represent linear transformations in a natural way. Let's give an example of a simple linear transformation. Suppose my linear transformation is T(x, y) = (x + y, 2y – x). Imagine (x, y) as a coordinate in 2D space, as usual. This transformation T transforms the point (x, y) to the point (x + y, 2y – a). So, for example. T(-2,1) = (-1,4), T(5, 3) = (8, 1), etc. Now suppose I want a matrix that represents my transformation T. Let's do this by writing the coefficients of x and y as the entries of this matrix. Like this: 1 T = 1 (; )- Now comes the big step: I want to be able to write T(x, y) = (x+y, 2y – x) like this: 7(;) -(,"") x + y 2y – x 1 Since we chose T to be -1 ,we have: GOO-) 1 x + y -a + 2y The left hand side looks suspiciously like the product of two matrices, which should equal the right hand side. For this product to make sense, I need: (* ')()-(**)- x + y and (1 )()-(--»). -x +…
