    - Microsoft's future policy for redistributing Xbox 360 games? I don't know if running on xbox 360 is essential to your idea, if not, you can always work on the Windows version. Although that has some hardware requirements which your students/lab may not have. I also wish MS would clarify the distribution strategy. Sure, you can zip up the source and pass it out like candies. But no one can run it unless they plop down $100 for Creator Club membership.

    - Trying to pass a cubemap.dds to a fx shader Darkside, Thanks for taking the time to have a look and respond. If I replace Environment with a texture parameter then I get a compile error as the lerp function needs it to be a float4. If I don't load the parameter and hard code the texture location this does not work either, pluss this would be *** as I would want to change the environment of my reflected model as it moved from scene to scene. Surly this should just work as the shader is part of a MSDN tutoral and I would have thought that the XNA development team would not leave out cube maps :) I just cant for the life of me see why it is not working... If you have any other ideas I am all ears :) Thanks in advance :) Tag: XNA Framework Bounding Box of a Model after rotating (and scaling) it. Game Technologies: DirectX, XNA, XACT, etc.

    - XNA Graphics Performance Issues with GraphicDevice We have a ground, buildings, roofs and some meshes. The "map" is 64*64 pixels. We have between 4 or 5 meshes that have about a thousand polygons. We also have one or two static object with a thousand polygons. Nothing really that heavy I would say. Another point that might help you help me would be that on GP that runs shaders 3.0 it runs way smoothly than on mine. regards, Chryso Tag: XNA Framework Bounding Box of a Model after rotating (and scaling) it.

    - Models To me, it looks like your code should work. Although if you simply want to create dupicates of an object it would make more sense to store an array of positions rather than an array of models. You can then simply draw the same Model ten times per frame with each of the unique stored positions. Besides, when you create an array of 10 Models from the same asset name, I believe you end up with 10 references to the same object instead of 10 unique copies. Even if this is not the case, storing an array of redundant models would be a waste of memory. I'm not seeing anything at the moment in your code that looks like a problem.

    - How to load a WaveFront model? Ok, but i'm using the Mobile Direct3D Managed. As I know, this "version" does not support the .X format. So, instead of using the md3dm format that came with the samples, I'm thinking to write my own loader. Could you give me some tips For example, probably my WaveFront model will have a lot of vertices... what kind of structure should I use to keep this data in memory What class should I take a look Can you give me a simple example Of course man, i'm studying a lot :-) Thanks ;) Tag: XNA Framework Bounding Box of a Model after rotating (and scaling) it.

    - Is XNA the tool for serious game developers. Reviewing the majority of the posts here (XNA vs. C++/DirectX) It is a very powerful and fast development environment, however at the moment its range is limited to the Windows and Xbox 360, meaning that (at the moment ) you cannot develop as easily as you can with C++/DirectX for alternative next-gen platforms (Macintosh (hah, as if), Wii or PS3). I, however, haven't seen many remarks on the possibility to opening this to other platforms. Tag: XNA Framework Bounding Box of a Model after rotating (and scaling) it.

    - Here's How to use XNA GSE with the F# programming language F# is a research programming language written by Microsoft Reserch. It's still in its experimental phase, but I like to play with it. Here are my notes on how to use XNA GSE from F#. (Note: F# is an exotic programming language, and is harder to learn and use than C#. If you don't care about exotic programming languages, you're much better off using C#, since it's much easier and faster to use C# with XNA GSE.

    - What does creators club include right now? Yes but lets be honest here. During the first year I doubt there is going to be very much content released by developers on the 360 as they will still be getting used to XNA. Also, the content promised should have been available from day one. By the time there is stuff available its likely to be well towards the end of the year. So whilst I don't totally object to Microsoft charging for the creators club - I don't think its worth it right now unless you are desperate to try code on the 360. In fact there is no point joinging the creators club unless as a developer you manage to complete a working game on the PC, *then* by all means join the club and try it on the 360. To be honest though regardless of whether the creators club is worth it or not - I think the reason people keep questioning the price is that considering that Visual c# express and xna game studio express are free - why charge people just so that they can share their code on the xbox It does smack of being a bit of a rip off.

    - How I get the skin weights? I am not sure if I undestand completly, but I promise I will take a look on what you suggest. My big problem is just I don't have direct access to the vertex information of the models through the vertex buffer. So I modified the content processor to retrieve the vertex buffer and the index buffer in the Tag property in a raw data where there are only a streem of bytes that are difficult to interpretate. And it depends on how the model has been exported making things even harder. Nevertheless I dont care about the vertex buffer or the index buffer, what I really want is to have the vertex array, index array and the skin information, so I can manipulate the model in a convenient way. But I have seen that the processor doesn't get the vertex colors, so I decided to make my own .X loader and I am working with it for now.

    - Declaring alternative input devices Hi Many thanx for the immediate reply. Actually, I am doing a project which, among others, involves the feasibility of this operation, which is kind of crusial for the project. A guy from my university told me that maybe this could be done, without being really sure about it. Since you mentioned the need for the existence of physical devices, do you think that I could trick in some way the local machine to believe that my input (events) comes from the local physical devices Can I relate my input to that of the physical devices in a top level or should I go down to "interrupt level" (and really mess up everything :-)) Theofilos Tag: XNA Framework Bounding Box of a Model after rotating (and scaling) it.

    - Native Direct3D or MDX or XNA? Thanks Canuck1 for your reply. But I saw that MDX 1.1 is in sustained mode, 2.0 beta is dead. Consideringthe application can last for several years. It's better choose the right tool in the beginning rather than doing migration later, right The reason I put these 3 togather is to choose something easy to begin with and last longer. Native Direct3D seems the safest, but hard to use. XNA is in the first release. Will it be the same as MDX Also, I am not sure whether XNA can do all the jobs, like printing. The original application uses OpenGL. It treats a printer DC and Screen DC the same way. So there is no problem for printing.

Hello :)

I was wondering how I would go about getting the (axis aligned) bounding box of a model after rotating and scaling it

Re: XNA Framework Bounding Box of a Model after rotating (and scaling) it.

CodePfo

You can transform the box corners by the model's matrix, although since it's axis aligned it won't be useful for testing.

Re: XNA Framework Bounding Box of a Model after rotating (and scaling) it.

inthefields

Thanks for the answer CodePfo,

yet I fear simply rotating the AABB is not quite what I am looking for.

Rotating a model can change a model's AABB considerably. Think of a model shaped like a long tube for instance. When it is positionened along the z-axis it's bounding box is simply an unrounded version of the tube. Position the tube diagonally in the scene and the its bounding box will look completely different.

Re: XNA Framework Bounding Box of a Model after rotating (and scaling) it.

ClydeCoulter

Rotating the AABB can work (depending on what you're after) if you then reconstruct it into an AABB. using the mins and maxs.
