3D Models

Hi, need some advice. Just learning to program in Opengl and Directx and wonders what program is good for creating models or should I just make them from standard vertices. I also notice that Opengl front face uses counter-clockwise vertices and Directx front face uses clockwise vertices, will that make a difference to models when culling is on? Which way is the correct way, I can change Opengl front face to clockwise like directx, but do models''s created uses vertices that are clockwise base. I hope you can understand me Thanks for any help

The vertex winding does change rendering as VSD is usually based on the plane normals for all faces and if the vertex order is reversed then the plane normal will point the other way and your VSD may become "inverted". This is very loose, but pretty much what happens. Just stick with the winding you like. I use clockwise winding (I used to programme DooM engines and their ilk when I was a bit younger, so that explains that one).
Vertex winding is really your choice.
I suggest 3D Studio Max. Or if you dont want to spend $3495 on it you could try gMax which is a free simpler version. Should be enough for most needs, I think.

3D Canvas is great. Three types and prices from freeware to Pro for $69.95. Pretty much any format you could want, including .x.

again, i''m recommending milkshape. very easy to use, only $2o, also exports to .x

texture support only goes up to opacity maps though, but that shouldnt be a problem

Hi,

I think winding difference should not be the problem : since the drawing instrunctions sequence is different for OpenGl and DirectX, you can tune each code to have the correct winding.

Usually a triangular face reference vertex in a given order, so all you have to do is using the native order in one case and the reverse order in the other case.

As I understand it, gMax is NOT a free, cut down version of 3Dsmax, but a special version which is designed for creating mods for games which support a special gmax plugin.

In otherwords, it would be completely useless for designing your game models unless you already paid for the full version of 3dsmax to support the plugin.

Correct me if I am wrong.
