• suhalka 16 channel Real Time signal rendering: Should I go for DirectX?

  I'm refurbrishing an old VB6 application that displays up to 16 signals, at 100 samples per second, along with some icons on the screen. The user decides on the on-screen resolution by means of a zoom function key. Now in the design phase, I need some more information to decide on taking Direct-X or GDI+ path. I've been going through several sample applications, and so far, I've got the feeling that Direct-X is suited to heavily drive the ...Show All

• taumuon Geometry.BoxBoundProbe not working as intended?

  Hi, yesterday I was writing the collision detection code, and I had a really pain, figuring why the code: Geometry.BoxBoundProbe(BoundingMin, BoundingMax, Position, Direction); isn't the same as: if(BoundingMin.X<(Position.X + Direction.X) && (Position.X + Direction.X)<BoundingMax.X)    if(BoundingMin.Y<(Position.Y + Direction.Y) && (Position.Y + Direction.Y)<BoundingMax.Y)      ...Show All

• WirbelCarpe Clipping text in a GUI

  I'm currently designing a graphical user interface for a game, and got a problem when I implemented scrollbars. Rendering only parts of the graphics in the interface (when part of a GUI element is outside the viewable area of the window) was simple, but doing the same when using the DrawText function seems much harder. I ended up rendering the text to textures, and drawing only parts of those, but this can add up in texture memory usage. Is t ...Show All

• Sysmex DirectX 8 SDK Library link problem

• Mindking MDX Sprite Class Issue

  I am trying to create a MDX Sprite object using the constructor that takes an IntPtr to an unmanaged ID3DXSprite object. I have already setup the code to do this and it works for everything else I do (I do this for the Device and Textures and it works just fine). However, if I do this for the sprite my program crashes. I even tried creating a sprite using the constructor that takes a Device reference (my Device was also constructed with an ...Show All

• zs [MDX] Constrain cursor to fullscreen window?

  First of all, I'm not at all sure that this is a DirectX question or a C# question. If it is misplaced please tell me so and I'll repost it elsewhere. But here goes: I have two monitors in dualview, that is: if I move my cursor to the right of my screen it pops up on the other screen. When I'm in windowed mode I would like this behaviour but in fullscreen I would like to constrain the cursor to the primary screen / the fullscreen application. I ...Show All

• Dmitry Shatilov Managed DirectX 2.0 Beta and XInput

  I have a general question regarding the Managed DirectX 2.0 Beta: Using Intellisense, I was able to figure out how to get a Direct3D Device up and running dispite the minor (and sometimes major) differences. I also found that XInput, in contrast to programming with XInput in unmanaged C++, this version is lacking a lot, such as all of the core functions that update and get the state of a controller. Forgive me if I am completely off the ma ...Show All

• Kevin Scheidt XBox - Managed Code

  I’m just wondering if anyone knows if Xbox 360 supports any type of managed code (mc++, c#). We're about to develop an engine and we can’t find any information about this. We wanted to use c# for the scripting of the game so if anyone knows it would really help out. Thanks. There's a ton of wishful thinking with managed code for the Xbox 360, but a close examination of their Xbox360Preparation file says the fol ...Show All

• Venkataraghavan Sheshadri Directx 9.0 with C# 2005 Express

  I saw some great Webcast videos on MSDN Introducing 2D Gaming with C#. I have downloaded and installed, DirectX 9.0. The videos referenced Visual C# 2005 Express. I downloaded some sample code and tried to run it. The error was it couldn't find the Microsoft.DirectX referenced.

• beatriz_da Problem solved

  It appears that when I close the lid on my laptop, my program receives a DeviceLost message, but the program never receives the DeviceReset message after the laptop is re-opened.  The same thing seems to happen when the screen saver runs. Any suggestions Thanks, Jeremy P.S.  The source code is here: http://gosub.com/OpenSource/DirectXControl/DirectXControl.htm (it's a free DirectX control) ...Show All

• Jim Hollcraft Does DirectX have the OpenGL equivalent of Display lists?

  As the subjects asks, is there an equivalent  feature in DirectX Basically I want to just render about 200 spheres most of which will be the exact same copy of each other. Drawing each sphere independently of each each other gave quite poor performance in OpenGL until I used Display lists which enabled me to save a fixed set of drawing commands and just call the display list instead of redrawing the sphere each time. ...Show All

• Andreas Pollak Lighting problem with Dec2005 SDK?

  Hi; I can't get lighting to work with the dec2005 sdk. I created a simple cube mesh in maya, exported it, and loaded it into my project. But it shows up dim and faint - in fact the only light that seems to be showing is the ambient light. Here is my light code: Device.RenderState.Lighting = True Device.Lights(0).Type = LightType.Directional Device.Lights(0).Diffuse = Color.White Device.Lights(0).Direction = New Vector3(0 ...Show All
