ok thanks http://www.opengl.org/discussion_boards/ubb/smile.gif

I'm trying to create a particle system... and I have a question about speed.

is there any difference in speed if I do any of this examples:

1) use one triangle with texture and then use...

but what if I want to use multi-texture then?

ok.. thanks..

can I use glDrawArrays() if I don't have any shared vertices and use the above sVertex8f structure?

I have a object class that imports .Ase files from 3DS Max 2.5..

the arrays I have is this

struct sFace {
int v[3]; // 3 vertices for one triangle
};

struct sVertex3f {
float x,y,z; //...

Thanks for the answer PK.

now I understand. and I already use that type of pointers. my FileManager is buildt that way. and my render class

ex.

class C_Renderer {
// some private stuff...

my new engine does not use textures yet.. I only use the glMaterial stuff.

well the MyEngine->StartEngine(hwnd); starts the renderloop in a new thread that's why I have it that way.

The World->Render(); is a function to render all objects in my world class.

I got an idea how to create my engine.

is this a good way ?

first I have created a main class called C_ICE3D. in that class I have a virtual Render function and a pointer to my renderer (only...

I'm intrested in all the parts.. I want classes for world, camera, object and so on and then a render class that renders everything

I have made my own nice Object class that imports .Ase files exported by 3D Studio Max 2.5 but I have a problem with Texture coordinates when using vertex arrays

how do you keep everything under control do you have a class for each thing.. like Object class, Camera class, Light class, Texture class, Vertex class. And then a big "OpenGL" Class that start's the...

I just want to know how they work... like 3D Studio Max.. does it use 4 different OpenGL views 3 "2d" (ortho) for top,front,left and one 3D ? and how do they setup 4 different views in the same...

is there any good tutorials in this.. or can anyone explain it to me.. I don't understand where to start..

I guess you knows alot more then I do about C and C++ difference http://www.opengl.org/discussion_boards/ubb/smile.gif

I use both C and C++ so far becouse it is easy to use for me.. and I just...

but if there isn't any difference in speed or C is faster then C++ why did they make C++? is it only for classes and OOP stuff ? or is there anything they changed ?

Is there any difference in C and C++ code layout? or is it the functions that are different ?

and ofcourse you can mix them and use both.. but I wounder why do that if they do the same.. if it is...

this is little of topic.. but I still want to know which language you are using ?
