• Karthik R 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 ahh thanks for that info. i was doing some testing in visual ...Show All

• rurounip retrieving more than 4 values per texture lookup

  Is it possible to have a texture with more than 4 values per texel My problem is, I need to look up a chunk of many values (about 16) multiple times per pixel and I like to do that quickly. In my setting more than three 2d texture lookups each time (= 12 float values) is the maximum I can allow without a significant performance drop. Also if anybody has experimented with 64 or 128 bit textures I'm interested to know about the performance ...Show All

• JinMengcheng statically linking D3D?

  Hi there, Might seem a dumb question, but I'm wondering whether it's possible to statically link with Direct3D/other DX components; I realise the application size would probably grow to the nth degree, but at the moment that's not a problem.  The reason for this is that I seem to be having difficulty with machines that have different versions of the runtime on (eg October 2005 vs February 2004) with missing DLLs (d3d9_27.dll is the latest ...Show All

• india7 Is the returned Stream object from Include.Open() disposed automatically?

  Is the returned Stream object from Include.Open() disposed automatically Or I should take care of it manually Yes, internally that stream will be closed when the underlying D3DX object is done with it. (If you're familiar with the unmanaged version of the functionality, the stream is closed when the ID3DXInclude::Close member is called by the unmanaged API). Well. I've found it disposed automatically be ...Show All

• simdoc dxwebsetup wierdness - deployment with app

  Hi, sorry to post this in this forum, I am unsure where to post it. OK here is the thing. I have a deployment problem. I am creating a setup with my app, created in VS 2005 Pro, using C#(.NET 2.0)   This app of mine requires DirectX runtime end user files, or the SDK but really the runtime files. Now, during installation, I bundled in the dxwebsetup.exe. This executes fine.   2 main problems here already: 1 ...Show All

• AmatuerCoder Code behaves differently on 3 different computers. ???

  I have a C# application that displays fairly simple 3d models (mostly lines and a few faces).  I am using Managed DirectX 9 August 2005.   On one computer (the development machine) the program runs fine.  On another computer, the lines don't draw (it's a call to drawIndexedPrimitives, type lineList) but the meshes do draw...and on two other computers, when I open the Form that has the 3d control, the computer freezes (before ...Show All

• COGEE Managed DirectX

  Besides the 5 forums already there, a seperate Managed DirectX forum Or is the amount of people working with managed directx still too low Regards, Wytze Ok, Thanks for clarifying the reasoning behind this and I agree. Regards, Wytze The answer is "neither" We love managed code as much as native code, and we made a deliberate decision (at least for now) to not separate ...Show All

• soundman32 Animation in directX continue

  I'm DirectX begginer, trying to animate flying bird. I'm exporting the bird object from 3d max8. I don't undestand if animation is done by DirectX (and how), or I have to do it in 3d max before export to DirectX. Normally the bird's wings will be animated in max and then you'd use that animation track in your program. The movement of the bird will be done programmatically. (This is not the only way, but it's ...Show All

• Hirén Players move faster at higher framerates

  Okay, this is really bad. Clearly, a hard-coded "2" that's applied to my character's "Left" property on every frame render isn't going to cut it. Obviously, the game will run slow on crappy hardware, and there's not much I can do to prevent that. But the game shouldn't run faster on really good hardware! How can I cap the movement speed, or better yet, guarentee a certain speed within reason I can already calculate frames per second, and h ...Show All

• Sstar Error 1920 on 2006 directx SDK install, MDM.exe issue?

  I get: "Error 1920.Service DirectX Debug Service (DXDebug) failed to start. Verify that you have sufficient privileges to start system services." When attempting install of the 2006 febuary release of directx sdk. I'm using vc7.1, and the only user of this machine, all privileges, etc. I've read elsewhere that this same error with the 2003 summer release was caused by mdm.exe issues. Is this caused by a missing mdm.exe, another servi ...Show All

• W-i-s-e_G-u-y I need some spiritual DirectX guidance.

  I've been learning from a book titled Tricks of the Windows Game Programming Gurus by Andre' Lamothe. It's outdated using DirectX 7.0a SDK, and I believe his second volume creates software rasterization with DirectX 8.0 SDK. I really enjoy his books because it is very in depth and low leveled. My question is should I continue reading it if I'm geared on becoming a professional in graphics Since 60% of our life is maintaining and upgrading previo ...Show All

• FuSu DirectX Template

  I just thought of a good idea. Use Visual C# 2005 to make a template of the DirectX Empty project sample. Use the template as a starting point for DirectZ DirectX I can't type. Just an idea It's a fantastic idea and I encourage that. Us programmers are a lazy bunch and once you have the template up and running. It's always a nice way to start out a project. Clean and simple. :) I hav ...Show All
