   DX questions
  Hiwhat's the diffrence between :1- Direct3D and D3DX ?2- texture and material ?1000 thanxx   
  Direct3D is a 3d rendering API, while D3DX is a library of helper functions for Direct3D.A texture is an image, while a material describes light interaction.I think you need to spend a year or two learning the basics before you go for GI, that you asked for in your other post. It's a fairly advanced subject, and doing it in real-time is everything but easy.   ;one thread is enough thank-you [smile]
