      • I've been working on a modelprocessor that grabs animation data using the default importer. I've managed to get my own fbx files and tiny.x to animate correctly but I noticed the default importer actually gives me animation keyframes for the body node. They're keyframes at time 0 and time 1.0333333s and they have the same transform. If I use the inverse of the body node's keyframe transfor

      • A game I have been developing works perfectly fine on windows, however, causes my xbox to hard freeze (all controls stop responding and the device can only be shut off from the power button on the xbox itself), which in turn detaches the debugger. This seems to happen after an arbitrary amount of time, and thus leads me to perhaps memory issues. I haven't been able to find anyone else with a simil

      • I have an object that I am trying to rotate with the xbox game pad. The rotation works as expected except for when the object is rotated upside down (on its x axis). When the object is rotated upside down the rotation along the y axis is reversed, but if the object is rotated back to its upright position the rotation is fine. I don't believe this is a gimble lock problem. I have also tried many ot

      • Can someone please recommend a few good resources for creating some basic ray tracing engine code for someone familiar with DX9 raster graphics. Specifically something with coding examples and how/where/when to use shaders in conjunction with ray tracing. Also, something that has been created/written within the past 2 years, not things from pre-DX8.1 days. Thanks.

      • I'm wanting to port my XNA Beta 2 games across to the 360 but before I start I have a couple of questions about the screen resolution. I'm wanting to be able to support standard def 4:3 and 16:9 as well as high def 4:3 and 16:9. Now, for the aspect ratio, I'm assuming I can just create a project matrix with the correct ratio, like: Matrix.CreatePerspectiveFieldOfView(MathHelper.ToRadians(45.0f), 1

      • Is there a way using the sprite batch object that you can render several rectangles, but when alpha blended, it looks like the entire object was rendered first as a single opaque image, and then that image was alpha blended, such that you would never have known it was several smaller pieces assembling the final object Instead of normally seeing each rectangle blended as it overlays another rectan

      • I am trying to create some methods to manipulate various parts of the XNA vertex structs. I want to be able to pass all the different vertex types as arguments to these methods. Because they are structs they don't derive from a base class other than ValueType. If I use ValueType as the parameter I don't have access to the propertys of the vertex. Is this a case where refelection would be usefull C

What is the difference between those two flags Isn't a back buffer not a render target ... I can't think of anything that makes a back buffer so special to give it its own flag :-) Enlighten me please, - Wolf
