Is it possible to draw lines just using a effect I want to draw a line for each axis of a model.

      • Hi everyone. I seem to be having an interesting problem in my test app. It should draw a circle of points (please look at the Sub below). What it does is that in debug mode it draws an ellipse (in fullscreen) and if I run it as an executible it draws a circle. Do you know why :) Private Sub OnBufCreate( ByVal sender As Object , ByVal e As EventArgs) Dim buffer As VertexBuff

Is this possible I've seen information on creating a vertex buffer, storing data in it and then using it for rendering, but not information on creating a vertex buffer and storing it into a ModelMesh or even BETTER, taking a ModelMes

      • Hi, I had a question about controllers that plug into the PC. I understand that only XBox 360 controllers are supported by XNA. I also understand (I think) that wired only controllers work as they need to be plugged into the USB port on the PC. Actually the last point is now not valid since I discovered the wireless controller for Windows and 360. But this isn't available until 2007. Does anyone k

      • Hi! I'm just in the process of writing a proper text rendering component for XNA. It fully integrates into the content pipeline and can import any TrueType font during compile time. Just like any other XNA framework content, an .xnb file is generated from the font which can at runtime be loaded by XNA's ContentManager, eg. BitmapFont myFont = this .content.load< BitmapFont >(   "Conten

      • Hi folks, I've searched for and read several threads on exporting .fbx files from 3dx Max, but I'm afraid my newbiness leaves me with more basic questions than others are asking. I have no trouble exporting an .fbx model from Max and displaying it using GSE/XNA -- in fact, it even works if I add a little basic material within Max, such as a simple solid blue material. My troubles begin when I a

      • Hi, I've been digging around the architecture of the 360 and noticed the PowerPC chips inside have In Order Executiong (IOE). After looking around some more, apparently the Wii and the PS3 also have IOE. Is this coincidence The first XBox had the intel x86 processor which had Out of Order Execution (OOE) and therefore branch prediction. After more investigation the only advantage I could see for
