I appear to have sorted it now.

I had all sorts of transparancey things going on and had turned off depth buffering which caused some problems.

All sorted though.

I have a 2D scene drawen using lines and quads and triangles. The lines etc that I want to be hidded by say a box I move in the z direction so that they appear behind one another.

When I turn on...

With regards to glDrawPixels I need to include the functionality within Visual Basic however I am having difficulties.

Does anyone have an example of how to do this?

Many Thanks

I have loaded an ASE file sucessfully and viewed it as a wire frame however when I try and load the face and vertex normals for the mesh and light the scene only a handfull of the pannels are visable...

Where does the colour information come from in the ASE file format?

Simon

I have 3DS MAX Studio so I can load the 3DS files and export them as ASE files.

I understand that the ASE file is less complex and will probably give me all the data that I need however I am still a bit concerned about these colors aer you saying that if I read in the ambient...

Which format gives the following?

Vertex Data? (XYZ)
Face Data? (Vertex Numbers #1 #2 #3)
Vertex Colors? (RED GREEN BLUE)
Face Colors? (RED GREEN BLUE)
Normals to FACES and VERTEX's?

Thanks...

So are 3DS files the way to go instead of ASE files?

Simon

In Lesson 14 you can put OPEN GL text on the screen however how do you change the size of this text? There is a line which says:

I don't know if this is what you ment but firstly I did

glColorMaterial GL_FRONT, gl_diffuse
glEnable GL_COLOR_MATERIAL

but also used

glColor3f for each color that I set

I presume that you mean in my case
glmaterialcolor3f.

I tried this but the program won't compile glmaterialcolor3f is not recoqnised.
