Drawing in C++

BANANAMAN · Oct 26, 2010

So I managed to "draw" a square with some basic C++ code.Question is how do i make it into a Cube? Also how do i make a circle into a sphere,a Triangle into a pyramid,etc? How does one code in C++ to make 3D objects?

Darthfett · Oct 26, 2010

Wouldn't it simply be determining where the camera is facing, to determine where vertices are, and then filling in the visible triangles?

I'm still new to this whole thing too, but that would seem like a logical way to do it. A library would, of course, be something you'd want if you didn't want to do a whole bunch of math calculation yourself.

Slapshot136 · Oct 26, 2010

mind showing what code you have? (I haven't done any drawing in C++, only java)

BANANAMAN · Oct 27, 2010

Here's what i have so far.

Code:

#include<stdio.h>

 

#include<glut.h>

 

void Scene();

 

float fSphRadius = 0.08f;

 

float fSphX = -0.8f;

 

bool RightHit = false; 

 

void main(int argc,char **argv){ glutInit(&argc,argv);

 

glutInitDisplayMode(GLUT_DEPTH |GLUT_DOUBLE |     GLUT_RGBA);

 

glutInitWindowPosition(0,0);

 

glutInitWindowSize(800,800);

 

glutCreateWindow("First OpenGL Window");

 

glutDisplayFunc(Scene);

 

glutIdleFunc(Scene);

 

glutMainLoop();}void Scene(){  glClear(GL_COLOR_BUFFER_BIT);   

 

glPushMatrix();

 

 

 glTranslatef(1.0f,0.0f,0.0f);   

 

glScalef(0.3f,1.0f,0.1f);    

 

glutSolidCube(0.8);

 

glPopMatrix();

 
 

 

glPushMatrix();     

 

if ((fSphX >= 0.75f) && (fSphX <= 0.85))    RightHit=true;

 

if (RightHit)  fSphX -= 0.004f;

 

else  fSphX += 0.004f;

 

glTranslatef(fSphX,0,0);     

 

glutSolidSphere (fSphRadius, 100.0f, 100.0f);

 

glPopMatrix();    glutSwapBuffers();}

Ah, you're using OpenGL. You already have a cube and sphere there. My guess is, you don't have lighting enabled, so all the faces have the same shade. Try enabling lighting and add some light sources.

BANANAMAN · Oct 27, 2010

How do I do that?

Xienoph · Oct 27, 2010

I don't remember how (or rather, don't want to remember the nightmarish graphics course I took). But here's a tutorial on how to do lighting.

Also check out other tutorials on that site. They're awesome.

Quick question:If i draw a square with GLUT_LINES or whatever instead of CUBE is it always 2D?

saw792 · Nov 3, 2010

Well it's more like a square in 3D space. Which means that if you rotate around 90 degrees to the side of it it won't be visible. Instead of using glut functions to draw your shapes you're better off doing it with proper GL calls anyway, they are much more flexible for things like normals (how light bounces off the surface of an object), texture coordinates (for mapping images onto the sides of a 3D shape) and obviously allow you to make shapes not available in the GLUT library.

As Xienoph said, check out Nehe's OpenGL tutorials, they are an excellent starting point (although they don't use the latest features of OpenGL 2.0, 3.0, 4.0 etc). I've had to use OpenGL in Java for a university project and it was quite a learning curve.

BANANAMAN · Nov 5, 2010

I did and this error continues to bug me to no end.

"gl\glaux.h: No such file or directory."

Any advice besides telling me to code in something else?

Something completely random:Apparently you can draw a 3D Teapot with GLUT....

saw792 · Nov 5, 2010

Well you have to import all the OpenGL required libraries and headers... which means that you must have a folder named gl with the libraries in it, assuming you are following the tutorial. You shouldn't need glaux anyway, it's outdated and you can do all the things you need without it.

Check wikipedia for the history of the teapot in computer graphics

BANANAMAN · Nov 6, 2010

So how do i import those? I tried Removing glaux from the code but now i get the ff errors.

any alternate suggestion on how to achieve the same effect without using glaux?

Ok so I copy pasted it all. But I only edit the code when it works so i have basis to fall back on when it goes wrong after i edited it.

Edit:I found an alternative to glaux Now i have the ff errors saying some variables are "undeclared" How do i fix this? I mean i know how to declare variables but the ff variables are new to me.

the NeHe tutorials are rather old and so is glaux.h and Dev-Cpp (CodeBlocks is pretty good but I prefer devcpp since I got a portable version of it)
I found glaux.h somewhere on my pc but I don't know if it works (maybe it requires a library or something)

I'd recommend to continue with learning opengl on another site than nehe or to download one of the other sample codes at the bottom of the page (sometimes one of them has working code)

ghostwolf from hiveworkshop made a collection of useful c++ links
you should have a look at it
