I think the previous problem was in the glBitmap.pas.

Anyway, I've tried it again with

Code:

 
var Model1: TGlModel;
...
model1 := TGlModel.Create(nil);
model1.LoadFromFile(extractfilepath(paramstr(0))+'3ds\spaceship.3ds');
model1.TexturePath := extractfilepath(paramstr(0))+'tex';
...
model1.Render;
 

... and I get the Access Violation again

(This time also without textures!)[/code]

Try this:

Code:

 
//in the uses
  glRender,
  Model,
  Model3ds,
  ModelObj,
  ModelX,
  ModelMsa;
 
//in the var section
scene1: TglRender;
 
//in the init part of your application
scene1 := TglRender.Create(nil);
scene1.AddModel();
scene1.Models[0].LoadFromFile(extractfilepath(paramstr(0))+'3ds\spaceship.3ds');
scene1.Models[0].TexturePath:=extractfilepath(paramstr(0))+'tex';
scene1.UpdateTextures;
 
//in the render part of your application
scene1.Models[0].Render;

Thanks for your help!
Unfortunately, I cannot see the loaded model - only the rest of my scene.
As said before, it worked with gl3ds except the textures and because of that I don't think that the model is too small or at a wrong position...

Code:

 
  model1.Models[0].LoadFromFile(extractfilepath(paramstr(0))+'3ds\spaceship.3ds');
  model1.Models[0].TexturePath:=extractfilepath(paramstr(0))+'tex';
  model1.UpdateTextures;
  showmessage(model1.Models[0].GetNamePath);
 

When I launch my application, the messagebox is empty

Is this again the problem with Char,AnsiChar etc. in D2009?

It should work in delphi2009.
But i do not know .GetNamePath
Try using .Path or .TexturePath

Are you willing to send me the 3ds mesh so i can test it?

Same thing with .path

I attached the 3ds now.
And thanks again for your patience

Ok with your .3ds file i also get an empty scene. Saving it to .txt or .obj with glModel and loading these instead give some nice error's. So somehow glModel is having problems reading your .3ds file properly.
What modelling software did you use making the .3ds file?

Anim8or

But why did it work with gl3ds? Is there a better possibility to export anim8or-models to 3ds, maybe with Blender somehow?

Anim8or should be fine, i have not used it for a while. I will investigate why it does not work with glModel.
Also try exporting your model as .obj from Anim8or and load that one.

As obj: "0.533 ist kein gültiger Gleitkommawert" (-> is no valid real value?). It is always the same number, even if I convert another model...

Oh you need to set the following in your application to make that work:
DecimalSeparator:='.'; //always use . as decimal seperator if it is , for dutch language!
I guess only people with english or american country/language settings get away without setting that line.

Found the real problem now. When loading the 3DS file the visibility is read from TRI_VISIBLE and this is either read wrong in my code or set wrong in 3ds file.

You can solve this by setting:

Code:

scene1.Models[0].Mesh[0].Visible := true;

And give the default material a somewhat nicer color ...

Code:

scene1.Models[0].Material[0].DiffuseRed:= 0.0; 
scene1.Models[0].Material[0].DiffuseBlue:= 1.0; //make it blue
scene1.Models[0].Material[0].DiffuseGreen:= 0.0;
scene1.Models[0].Material[0].AmbientRed:= 0.5; //make it red'ish
scene1.Models[0].Material[0].IsAmbient:=true;
scene1.Models[0].Material[0].Name:='BlueMat';
scene1.Models[0].Mesh[0].MatName[0]:=scene1.Models[0].Material[0].Name;
scene1.Models[0].Mesh[0].MatID[0]:=0; //first material in model

Also .obj files written by Anim8or give some problems with glModel as the G tag is not where i expect it to be.

Thank you very much, this works!

Unfortunately, it doesn't load the materials, but for this project it is not too much to set them manually.
Also the 2nd Object in my model isn't loaded. I will export this to another 3ds and load them both to solve it

if you have 2 meshes/objects in your 3ds file you also have to:

Code:

scene1.Models[0].Mesh[0].Visible := true;
scene1.Models[0].Mesh[1].Visible := true;

So each mesh/object needs to have its visibility set to true.

But if i understand correctly if you set an material in anim8or to an mesh/object it does not show up? I will do some experiments this evening ...

Zitat:

i have not used it for a while

do you already have the newest version?

Zitat:

The fourth v0.97 preview is called the v0.97d preview dated September 21, 2008.

Sorry, my model has material! Now as I enabled the second mesh I can see the yellow color of the windows. Probably there's something wrong with my lights...

Considering materials and lighting read this: http://wiki.delphigl.com/index.php/Beleuchtung
so the light settings and positions and the materials settings together make how a material/color looks like.
