Question About Learning DX9

vgamecodervgamecoder Member Posts: 2
Hi I am new here. I have a few questions to ask. I have been learning a bit of DX9 from www.directxtutorial.com. I use Visual C++ 2008 Express Edition. I was wondering if anyone knew of any other/better places to learn DX9 from. http://directxtutorial.com/Tutorial9/B-Direct3DBasics/dx9B4.aspx This lesson. About vertexes(probably not the correct plural...). Is it needed? Like can I skip it? Because it does not seem useful to models that 3d games use. I even looked ahead and they did not even use the code from this tut. Just wanted to know. Don't want to waste time learning some thing I don't need to know.

    I program in OpenGL so I can reach users on Windows, Linux, and Mac instead of just Windows, but I can tell you that vertexes are very important. They make up triangles that are your virtual world and models. They describe the direction of force being applied on players, bullets, and any number of other things. I'd pay attention to that tutorial.

    If you want some live code, although not done in C/C++, you can view the UnrealScript (UScript) in UT, UT2003, and UT2004 with little effort and see how very often vertexes are used in 3D games. Almost anything that moves in your world will have a vertex to describe the X, Y, and Z axis movements.

    I do plan on learning OpenGL eventually but I want to learn DirectX first. But looking at that tutorial it used the vertexes only to make a triangle. I forgot about school math and what vertexes are and how I would need them for models too. Thanks for the good and quick response. I am now going to do that tutorial.
