Working C# Teapot Sample
Author
Hi there,
This is my first visit here.
I am not new to programming but am new to DirectX 9 (April 2006).
I read a lot and looked at some samples.
I coded a simple Windows Form Teapot Sample - Problem - it is still black.
I tried all tricks with lights etc.
Does anybody know of a simple working C# Teapot (or generic Mesh) sample with Ambient light.
I would be so greatful.
I am at the stupid point where I am missing something small and ... it is the world for me ... I hope someone could relate.
I promise to post the code of a "damn straight" one page sample - I just need someone to help me turn " the light on" :)
Many Many Thanks
Well, let's take a look at your code first and see what you've got. Odds says it's something simple that you're just overlooking (don't worry, we've all been there[smile]).

Hi AJ,
Wow ... somebody answered - Many thanks already!
Just open a standard Windows Froms project.

Add new Windows Form named "Meshes" and replace all of the code inside with

Oh ... well ... I got it right after so much pain.
I post the solution here for the frustrated souls out there who are just starting with DirectX.
Please understand the code - It is, as I promised, a "damn straight" representation of the concept ... deliberately kept with hadcoded stuff.
In my case I felt like "Yeah, sure I know how to drive - but where do I put in the damn ignition key" - Hence - elegance of code-writing was not an issue in this case.
It is my first 3D code, where I, in complete desperation, stripped bits and pieces fwom Tom Miller's book (Which DOES NOT compile with the latest DirectX) as well as from the SDK samples.
How to "install" the code - see my previous postings. Just make sure you put somewhere the files teapot.x, tiger.x + tiger.bmp (from Tom Miller and the April DirectX SDK).
This code does compile and run.
Just play with the camera position settings as well as device.Transform.World
I am sharing this with you but please - you are sincerely welcome to critisize the code in case you see improper use of devices, initialization etc.
For example I could not use any of the "device.Lights[0]" settings - If a guru reads this - please feel free to comment.
Anyway - here the code:

Hi, glad you figured it out, but a little helpful tip: use [ source ] and [ /source ] tags (without the spaces), it is incredibly useful. People tend to complain if there arent those tags.
For example:
For example:

Oh yeah - I see - didn't know - thanks :)
And thanks for actually implementing it.
