this file i just uploaded is a powerpoint presentation that i have been foloowing to solve this task it should help understand what i've been doing and where i have gone wrong

[Craigspaz]

I noticed a few things in your code the first thing is that in your DXHarness.cpp I can't find the file d3dx9.h. I think it should be d3d9.h. When running your code in debug mode then it says that your typcode and pNext variable could not be evaluated and so I think that the problem is somewhere in your texture code. You should take another look at it.

Hi CraigSpaz
both #include <d3d9.h>
#include <d3dX9.h> are in the DXHarness.cpp file you need to make that you have the sdk installed on your PC and included in the project

[S_Dass]

to include the sdk library in the project you need to go on project properties. I recomend downloading the june 2010 sdk. once this is done go onto project properties (or RayCast properties after selecting the project tab on the toolbar) once a menu appears click on configuration properties drop down menu and click on the C/C++ drop down menu, after that click on general and there will be a menu of options, one called AdditionalIncludeDirectories. Click on this and browse for the sdk folder downloaded and that will get rid of #include <d3dX9.h> error

Thanks

Did you copy the code from somewhere of did you write this yourself?

[S_Dass]

I only wrote the code that is commented with the steps in the void view::RayCast so steps 1 to 7 everything else was provided for me
