  1. Not sure if this is true where you are, but in the US the difference is can be viewed as applied science versus pure science. Comp sci leans toward the theoretical aspects of computers and computer software. Electrical and electronics engineering, on the other hand, are almost entirely practical, involved in the design and manufacture of hardware and software. You have to decide which one you are more comfortable with and what your future goals are. Multiple degrees are good if you are going to teach or work in administration/management. If you are looking to do hands-on work, then you need to focus on a particular discipline. Experience becomes much more important than advanced or multiple degrees in that case, other than maybe a masters specific to a particular field.
  2. Where to go to learn 3D modeling...complete beginner

      For the past year or so, both Autodesk Maya and Maxon CINEMA 4D have been offering "student" versions for free. I don't have a link, but I see this mentioned all the time in my son's minecraft forums, where there are a number kids making YouTube videos with Maya or C4D.   As someone who is proficient in both of those programs, I will state flatly that there are no good books for learning CINEMA 4D. For years, I have been buying books in English and German in an effort to learn the program, and none of them are particularly good. (If anyone wants to recommend one, I will buy it and read it.)   On the other hand, I was able to learn Maya within a month or two using a combination of YouTube videos and the two most popular books on Autodesk Maya on Amazon. (I forget the names...) It's not that Maya is so much easier than C4D, it's just that the teaching is done by professional educators, not 3D artists who fancy themselves teachers. It seems that Autodesk is involved directly in their training...   I would also add that you can buy a lot of 3D models for cheap on the web nowadays. That way, you only have to know how to make modifications to existing models, which is much easier than doing the modeling yourself.
  3. How do I take a white bitmap font texture and modulate it with another color at render time? I was able to do this in D3D9, but I am unfamiliar with DirectX 11. Can someone point me in the right direction?
  4. Any programming tutorials?

    I have a series of free iPhone game programming tutorials that I am working on: http://www.johncmurphy.com/product.aspx?pid=368 I have several more planned...I just need to get the time to record them.
  5. Pong AI?

    Here's an interesting paper on Pong AI from CIG: http://cswww.essex.ac.uk/cig/2005/papers/p1038.pdf
  6. Collision detection for billiards simulation

    Based on that link, it seems like a sweep and prune method would work well. It would get rid of the whole problem created by used a grid overlay (quadtree, k-d tree, etc.) when a ball overlaps a couple of grid spaces. Instead, using bounding spheres and a sweep and prune method, I could quickly scan for any potential collisions before going ahead with more in-depth collision detection. Thanks, I'll give it a try.
  7. What is the "best" collision detection method for a billiards simulation? Assume 16 spheres of identical size in a rectangular field with infrequent collisions. I am thinking that one of the tree methods would be best, but I am not sure. Thank you.
