Vertex 2 -0.4276 1.862 3.8984 {normal=(-0.01221 0.4969 0.8681)}
Vertex 3 -0.81184 2.1162 3.12242 {normal=(-0.0444 0.6719 0.74012)}
Vertex 4 -1.13479 3.3543 2.4625 {normal=(-0.09215 0.7945 0.60084)}

What model format is this?
Have you tried to google for code that loads and renders that model format?

hi Grolsch,
yup, tried to get sample codes from the net...but cant seems to find it. the extension of the file is .m

looking for ways to load the model using GL. Hope anyone here can help.. Thanks heap.

Didn't find the .m file format on wotsit.org. What program did you use to make the model? Or where did you find it?

[nexusssz]

can i email it to u...?

I would not be able to get much use out of it. Why don't you pick a more common 3D format?

easy.

first, you must parse the 3d data file and allocate the geometric informations into arrays(or struct, whatever suits your needs).

second, read data from the array and render it as usual.

actually, i see no problem here.

most likely, this is an assignment and you a just a beginning student. dont bother searching the net for loader, as this is custom made for your class. nobody even bother to make loader to this kind of data(ASCII, too many unnecessary words). there are other tips for optimization, but ill leave it for later, if you prove you can do the simple way.
