Crunch and Pack algorithms + curve algorithms
hi,
I am looking for good tutorials or books with different Crunch and Pack algorithms....
Iam also looking for a tutorial/ book witch explains how to generate a sinus or cosin table with a ML routine..
oh my god.. i am moving forward.... 6 months i already bought the book: Computer Graphics C version from Donald Hearn and Pauline baker... this is a very good documented book. lots of alogorithms. like circels. eclipse, 2d, 3d vector rotations. Bresenham, linedrawing and lots more..
but no Crunch and Pack algorithmes or methodes and also no sinus or cosin algorithms..
every body a happy summer!
bye Testa

You can also generate a series of sines from the first couple of entries with a little bit of arithmetic.
One of those trigonometric laws they made you use in school said something like:sin u sin v = 1/2 ( cos(u - v) - cos(u + v) )Which means that:F(x + 1) = F(x) * k - F(x - 1) Where:F(x) = sin(x * t)
k = 2 cos t Granted you need a multiplication function with decent precision for this to give reasonable results so I suppose you're probably better off mirroring a table on the C64. |
