    Comparing Shadow Mapping Techniques with Shadow Explorer

    I've done a small specialization at my university about aliasing on shadow mapping, Its not top quality, but perhaps could be useful to someone else: http://www.bondarev.nl/files/specialization_shadow_mapping_algorithms.pdf

    Debugging Memory Leaks in Visual Studio 2010 (c++)

    I use this type of implementation for this: http://www.flipcode.com/archives/How_To_Find_Memory_Leaks.shtml Doesn't work on malloc etc.   It will make your code really slow, but the awesome thing is.. you can add some extra functionality: -Record when the memory block was allocated. -Reset you memory-track-table -Output the table when you like to a file -etc.

    Are static member functions ever used?

    If you declare global static object in c/cpp file "static type gObjectName;" you cannot link the object from the header file by calling "extern type gObjectName;".

    How do I handle lots of textures

    You could combine textures into one large texture, recalculate UVs based on your new texture... should do the trick.

    Occlusion Query for Logic - not Graphics?

    First of all i like the idea, but it has some potential problems. -Possible problem is to drawing 360 fov view in single pass. If im not mistaking, projection matrix does not allow fov of 360. -Occlusion query stalls your GPU. Perhaps not important for you, but its good to keep it in mind. -The resolution will determain the precision of your approximation. -If to split 360 pass into 2x 180 fov, you will still face precision problems: low approximation precision on the edges. -also possible to split into 6x 90 fov passe, same way cubemaps are generated. i would defenatly go for this one. Modern engines use a very simple software rasterizer to solve occlusion problems (has still same problems for your solution) to stay away from gpu. Basic unoptimized approach would be something like: -draw all objects that are potential occluders in on cubemap (6x 90 fov). Except the one that will be tested. -do occlusion query test on object of interest on each of 6 rendertargets. -sum the result. In my opinion it will be a heavy process and not consistent. Have you considered to do any other tests then occlusion query? I would recommend to try something in direction of simplified object-models and raytracing heuristics. Like: Sphere1 - occluder Sphere2 - object of visibility interest. -is sphere1 aligned with sphere2 and how much? Can be tested with simple dot-product. -how does does my current fov effect the corelation of delta distance and sphere sizes. Good luck!
