      • Hi all I¡¯m trying to calculate the inclination of a bounding box over a primitive. The objective is to make a vehicle¡¯s displacement more realistic. I take the normals of the primitives in terrain, and I calculate the average of these. When I have the average normal, I need to use it to replace the up vector of the current model rotation. I have tried it

      • Hiya, I've got two sprites being drawn, and I want to use the layer depth paramter of the draw method to specify which one is on top. One has a layerDepth specified as .51 and the other's is .50. My current understanding is that the .50 one should be drawn on top of the .51, but what I'm seeing is whatever one is drawn first is the one that shows up on top - it's almost like that parameter

      • It could just be that I am a complete and total idiot but I have been looking for an easy way to draw a 3d model with shader effects (.fx file). I had orignally guessed it would be easy becuase of the Tutorial 1: Displaying a 3D model on the screen, but that uses basic effects, not an effects file. Can someone please show me a simple way of doing this because I am evidently too dumb to figure it o

I've created a simple GameComponent that initializes a VertexBuffer and an IndexBuffer in the LoadGraphicsContent method. The Draw method uses a BasicEffect (with default lightning enabled) to draw the vertices using the TriangleList primitive. I

I know I must be smoking crack, but somewhere a long the line I got the impression that XNA would enable a 3D environment in Internet Explorer. If we can put Ink on the Web, http://www.code-magazine.com/Article.aspx quickid=0512062 , then I think we should be able to put a 3D environment on the web as well

      • Does anybody know what PresentParameters.DeviceWindow is used for if anything I've got D3D running in a child window and it works just fine whether I set this parameter or not. Besides that, the parameter does seem a wee bit redundant since the device constructor takes the window as an argument anyway. So is this just a bit of legacy code that is totally unnecessary or are there situations where

After looking at the contents of the file, it appears to be very similar to the p1_wedge.fbx file that is supplied with the Spacewar project; same version and everything. I
