• mpietras DirectX Extensions for Alias Maya 7

  When will the export X for maya 7 be released Or is there a way to convert 6 binary or 6.5 binary too work with 7 Maya 7.0 licenses should be backward-compatible to 6.5. That's what I've been doing. Taking whatever source work there is, exporting it out as .ma file, edit the .ma file to change the "requires" statement from 7.0 to 6.5 (and remove any other requires like mentalray/cgfx/whatever), then import that into a new scene in 6.5 and ...Show All

• John MG Distorted texture after lost/reset device

  Hi, I'm drawing a textured mesh using DrawIndexedPrimitive, using an effect interface. After a windowed/full screen toggle the texture appears distorted. Interestingly when I draw another mesh in wireframe mode in the same render call the problem doesn't occur. Can somebody help Nico Fascinating, I've seen lots of odd things come out of directx but that one is so uniform in its oddness. Usually its a horribl ...Show All

• Joe Buys Shadow maps

  Hi I'm looking for some information about texture shadow maps. I've looked in goole for a sample, but i can't find one. The ones I found, or are incomplete or too complex (because they involved other more complex concepts, like soft shadows). The sample about Shadow Maps in the DX SDK run soooooooo slowly that it is very hard to properly study it (I think that's because it is meant for DX 10). What I'm realy looking, is a sample code as simple a ...Show All

• jayson.ws.tool.ci.ftsp Error ding when all is well

  Hi all, I've built an application on top of the EmptyProject sample in the SDK. The application exits cleanly, but for some reason it raises and error sound. If I close the app with the close button on the window, the sample framework gives me a messagebox indicating that "The device has a non-zero reference count, meaning that some objects were not released," yet when I exit using the the GUI I've developed (which simply calls a funct ...Show All

• olivier durier slow backbuffer lock

  I need to grab all my rendered pixels and pass them to a video card in order to show graphics on a tv. I can do so by locking the backbuffer and moving the pixels, but in my test it is quite slow. My framerate drops to abour 1/10th of the previous speed, and that is just too slow. Is there a faster way of moving my graphics onto my video buffer than lockbackbuffer and lockrectangle There should be faster ...Show All

• i2adnan WEIRD-Please Help. Alpha Blended Mesh Occludes Another Mesh Over Background

  Hello everyone, I'm new to these forums and have been tinkering with Managed DirectX for a few months now in order to get my graphics engine working the way I want. Right now I'm trying to figure out a problem I'm having with two alpha blended meshes occluding one another.  I use a background sprite texture to help display the translucency of the meshes I'm using.  I have two distinct mesh objects defined, one created using Mesh.Box() ...Show All

• Ugla How do you apply a .fx effect to a mesh?

  How do you apply a .fx effect to a mesh I've looked for sample code but the only thing I could find was the SDK documentation, but that thing applies it to custom vertexes... Seems everytime I try something new in directx, it never works the first time ^^;;; Perhaps a stupid question, but how do I use effect.SetValue() and what does it actually do You could just do it like yo ...Show All

• marcvs XNA Framework and the Number of Runtimes

  Hi, I am interested in migrating some projects to the XNA Framework in the near future. I'm curious if there's any decisions if the XNA Framework is going to have the DirectX .dlls within it to simplify distribution. Without it, I'm assuming there will be three runtimes (.NET, XNA, DirectX). I'm usually okay with two runtimes, but three seems a little too much. Has there been any decisions, or is it too early to tell still If so, please consider ...Show All

• mike1942f Converting to .NET 2.0 - Device exists in 2 places

  I have a app I wrote in .NET 1.1 and it breaks when running on .NET 2.0.  I figure that I could just rebuild it in VS 2005 with .NET 2.0 and then debug it to find where it breaks.  Unfortunately,  I can't get it to compile at all in VS 2005.  I get the following error.

• ThackerRobin Getting rendered graphics (quickly) from the card

  I had a thread about thins some days back, but for some reason I can not write into it now. I am faced with the task of rendering some graphics with directx and then copying that graphics into another card which generates a video signal. I need to feed it a new frame 25 times a second. The size is 720*576 The rendering does not have to be any faster that this. I have tried two methods of geting the pixels, and both are much too slow. On ...Show All

• chad_ Uninstalling DirectX

  I have version 9.0b and I was trying to upgrade to 9.0c, but got an error during installation saying a required cabinet file cannot be trusted. At first I just thought this meant the file to install 9.0c was damaged so I got a new installer from here, but got the same error. So I figured there was a problem with the DirectX already installed on my computer. I went into DXDIAG and after only about 30 seconds it crashed my computer while it was sc ...Show All
