This page is dedicated solely to efforts to develop quality 3D programs using Borland Products. I will share tidbits of knowledge which are key to success.
Turns out that Microsoft sent out a malformed library for DirectX 7.0a. This is the last version of Direct X where Microsoft did anything for the Borland user. Turns out that the library was put together incorrectly, so you will get errors whey you run the programs. I will write more on this later. For now, bookmark or link to this page, as it will be a great starting point for all of you wishing to program DX w/BCB.
Retired pensioner runs this company, BCB Tools. He's looking to sell it. It is basically a VCL library that lets you create Direct X objects.8 is considered a minor version of Direct X. I will spend as little time as possible documenting this version.
DX9 pretty much kicks ass. It got rid of Direct Draw, which is a shame, as a 2D app will always run faster than a true 3D app. Anyway, the focus is now on full 3D games like Halo and Doom 3, which all use DirectX 9.0.
