• Frank Babz Creating a new texture fails with "first chance exception"

  I have an application in which I create a texture to later write directly into. It works fine on my development machine, but on the target machine it fails with A first chance exception of type "microsoft.directx.diretct3d.invalidcallexception" occured. The code looks like this texture = new Texture (renderer.Device, 720, 576, 0, Usage .None, Format .A8R8G8B8, Pool .Managed); The pixelformat is the same as the device. ...Show All

• Cici D3DXLoadMeshHierarchyFromX issues

  I'm working on a project with skinned meshes and as part of that I use the function D3DXLoadMeshHierarchyFromX. Where I work there are 2 computers. They both exactly the same hardware, they run on the same os (winXP) and use the same directx version (april 2006). Ok, so on one computer this runs all fine, and as it loads the skinned mesh it has a memory jump of about 20-30MB, but it quickly goes back down again. The other computer jumps by ...Show All

• jonalder Enumerating Video Cards

  How Thanks, and were i look to see Video Memory There is a GetAvailableTextureMem function in the IDirect3DDevice9 interface that you can use.  However you're not gonna get a value like 64/128/256 (i.e. the actual memory size installed).  You don't really need to know the installed amount of video memory anyway. The IDirect3D9 inte ...Show All

• Vinny Pasceri MDX: Assigns a new mesh causes auto Dispose()

  I'm going through the Software skinning method as a learning exercise & I'm at the GenerateSkinnedMesh step, when I had to do this: meshContainer.MeshData.Mesh = newMesh What I'm finding out is that MDX calls Dispose() for the Mesh that's there before assigning the newMesh to it. 1) This is a problem because that Mesh is being kept around in the OriginalMesh property for later use & SHOULD NOT be Dispose'd of, and 2) Is there a way ...Show All

• James Juno Passing two normals for a vertex to the vertex shader

  I am having absolutely no luck with constructing my own vertex format and use it to store two normals for use in my shader. There are a number of flags which I can set to indicate various items such as position, normal, texture etc, but there is only one normal. How do I define that I want to use both normal and normal1 and for that matter normal5 I need to have a vertex which has a position and two normals. I tried storing one normal in a ...Show All

• Sarath25177 [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

• Steven I. [MDX 2.0.0.0] How to read pixel from back-buffer (or equiv.)?

  Hi all, I've working on this issue for a while now but I just can't find any documentation covering it or a solution which works in Managed DirectX 2.0.0.0 (Feb06 SDK). I'm working in C#. I am using shaders to render a scene which I want to then use to compute a deformation to a mesh. The trouble is, I want to look up values from a computed texture in CPU but when a texture has Usage.RenderTarget I cannot have Usage.Dynamic ( ...Show All
