• cbegg OpenGL Rendering Context + DisplayDevice (not window) Device Context?

  Is it possible to use a Device Context for a Display Adapter (not a particular window's DC) with OpenGL   The primary reason I am trying to do this is that I want to render OpenGL on multiple monitors, but the monitors are not necessarily members of the Windows desktop monitor group (and thus cannot have windows on them).  Here's some of my test code.  Everything seems to work until I call wglMakeCurrent(). dc = CreateDC( _T(" ...Show All

• Joshna about material

  When no light ,we can't see the texture.have a point light ,we can see the texture .So the material how to set I am assuming you are using C# and Managed DirectX. You can set the Material as follows. First you need to actually setup a material... This example shows a white material. private Material material; material = new Material(); material.Diffuse = Color.White; And then finally setting the material to the device which means that al ...Show All

• HidekiAI1 DX version

  Hi all How do you check what version of DirectX you have installed Thanks The first easy way is to have a look at the directory names in the program files directory of your machine. For managed code you can look at the post on the ZBuffer as it lists the sdk version/release that each of the managed assemblies hook up to.. I was more thinking along the lines of what version of the SDK I hav ...Show All

  Hi, hope someone can help me on my test environments, the installation is successful when installing manageddx files, which are needed for my app. I have to install during my installation these manageddx files from the redistributable sdk (April 2006)   This is installed fine on my test environments (plain vanilla images) but when it comes to finally installing it on my dev box, which already has these files installed, I get err ...Show All

• BryanMiller Mesh Intersect Confusion

  EDIT: Let me make my question simpler: How do I shoot a ray (using the Intersect function) from one mesh to another mesh Original Post: I recently found out that the Mesh.Intersect function requires you to transform the ray by the inverse of the Mesh's matrix.  I can kinda understand how this works with picking, but, I am trying to shoot a ray from one mesh to another with an arbitrary direction.  Now I'm dealing with TWO matrice ...Show All

• Kejpa Single or Double for vector floats?

  as i'm new to this. i was wondering if your only allowed single floats for vectors etc in directx. most of the code i've seen only has single float values. as i wanted to use the following unit scale 1.000 = 1 meter, 0.100 = 10cm, 0.001 = 1mm. with a max value of 99999.999 i think i'll need double floats for using this. so would i get away with this If you need a large range and continuous precision its worth ...Show All

• hackman_3vilGuy download sdk

  where can i download the directX sdk I've looked all over the Microsoft site and all i can find are updates. This is really fusterating thanks. I'm new to game dev. In order to simplify things, you can always visit http://msdn.com/directx/sdk and it will point you to the most-recent SDK.  In the future, you should use the full-qualified URL like Daniel used, as it it guaranteed to be an obsolete URL within ...Show All

• Tarkan G. Should I share one VertexBuffer for multiple objects of the same type?

  Hi, Imagine I'm creating a 2D game that uses sprites represented as billboards in Direct3D. Imagine it's a space shooter that contains multiple objects of the exact same type (some generic enemy ship, for example). Wouldn't it be inefficient to store a separate vertex buffer for each ship It seems as though it'd be better to share one vertex buffer for all the objects. Here are the two general approaches I can envision, using shared versus n ...Show All

• Michael Vainer a simple line

  New to directx, I don't need any textures or anything, but i need to make a simple wireframe model. And would like to know if there is an easy way to draw a 3d line just using 2 points as input(hopefully, as this is what im used to) { {x, y, z}, D3DCOLOR_XRGB(red, green, blue) } f means they are single precisions floats rather than the doubles that most languages default to. DirectX uses single precision for s ...Show All

• Biju S Melayil ID3DXFont and DT_WORDBREAK

  Hi, DrawText() in DX9 does not work the same way as DrawText() in GDI does when used with the DT_WORDBREAK flag. Punctuation marks in DX9 are wrapped incorrectly: This is a small text . The full stop is wrapped onto the new line. Parenthesis are also wrapped although there is no whitespace between the parenthesis and the preceding word: This is another (bla bla ) text. This behaviour can be seen in the Text3D sample of the SDK when the window is ...Show All
