OpenGL OpenGL run error

Recommended Posts

I have a problem with an OpenGL application I built. It works just fine on my pc, but when other users (non-developers) try to run it, it gives them a error and quit. The error, they say, is something about some "program configuration" and that they ought to re-install. Could anyone help me? I use MS VC++ 2005 Express with the following code:
#include <iostream>
#include<GL/glut.h>
#pragma(lib,"glut32.lib")
using namespace std;

float angle = 0.0;
float factor = 0.0;
float diff = 0.010;

void changeSize(int w, int h) {

if(h == 0)
h = 1;

float ratio = 1.0* w / h;

glMatrixMode(GL_PROJECTION);

glViewport(0, 0, w, h);

gluPerspective(45,ratio,1,1000);
glMatrixMode(GL_MODELVIEW);
gluLookAt(0.0,0.0,10.0,
0.0,0.0,-1.0,
0.0f,1.0f,0.0f);

}

void processNormalKeys(unsigned char key, int x, int y) {

if (key == 27)
exit(0);
}

void renderScene(void) {
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
if (factor>4)
diff=-0.010;
if (factor<1)
diff=0.010;
glPushMatrix();
glRotatef(angle,0.0,1.0,0.0);
glBegin(GL_TRIANGLES);
glColor3f(0.0f,1.0f,0.0f);
glVertex3f(factor*(-0.5),factor*(-0.5),0.0);
glVertex3f(factor*(0.5),0.0,0.0);
glVertex3f(0.0,factor*(0.5),0.0);
glEnd();
glPopMatrix();
angle++;
factor+=diff;
glutSwapBuffers();
}

void main(int argc, char **argv) {
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DEPTH | GLUT_DOUBLE | GLUT_RGBA);
glutInitWindowPosition(100,100);
glutInitWindowSize(320,320);
glutDisplayFunc(renderScene);
glutIdleFunc(renderScene);
glutReshapeFunc(changeSize);
glutKeyboardFunc(processNormalKeys);
glutMainLoop();
}


which gives me one warning : "main.cpp(3) : warning C4081: expected 'identifier'; found '(' "... Can anyone tell me what to a little noob like me can do to get this working... I have tried to throw glut32.dll and opengl32.dll in the same folder as the program when rar'ing it so people could use it. What to do ? :'( (and hmm, how do you make a code-box in here?) - madsravn

At the top of your code, it should be:

#pragma comment(lib, "glut32.lib")

you are missing "comment" keyword.

You need the VC++ 2005 Redist Package since computers without VC++ 2005 are missing some files (or file versions) that VC++ 2005 compiled programs depend on.

• A friend of mine and I are making a 2D game engine as a learning experience and to hopefully build upon the experience in the long run.

-What I'm using:
C++;. Since im learning this language while in college and its one of the popular language to make games with why not.     Visual Studios; Im using a windows so yea.     SDL or GLFW; was thinking about SDL since i do some research on it where it is catching my interest but i hear SDL is a huge package compared to GLFW, so i may do GLFW to start with as learning since i may get overwhelmed with SDL.
-Questions
Knowing what we want in the engine what should our main focus be in terms of learning. File managements, with headers, functions ect. How can i properly manage files with out confusing myself and my friend when sharing code. Alternative to Visual studios: My friend has a mac and cant properly use Vis studios, is there another alternative to it?

• Both functions are available since 3.0, and I'm currently using glMapBuffer(), which works fine.
But, I was wondering if anyone has experienced advantage in using glMapBufferRange(), which allows to specify the range of the mapped buffer. Could this be only a safety measure or does it improve performance?
Note: I'm not asking about glBufferSubData()/glBufferData. Those two are irrelevant in this case.

Before using void glBindImageTexture(    GLuint unit, GLuint texture, GLint level, GLboolean layered, GLint layer, GLenum access, GLenum format), does need to make sure that texture is completeness.

hi guys,
are there any books, link online or any other resources that discusses on how to build special effects such as magic, lightning, etc. in OpenGL? i mean, yeah most of them are using particles but im looking for resources specifically on how to manipulate the particles to look like an effect that can be use for games,. i did fire particle before, and I want to learn how to do the other 'magic' as well.
Like are there one book or link(cant find in google) that atleast featured how to make different particle effects in OpenGL (or DirectX)? If there is no one stop shop for it, maybe ill just look for some tips on how to make a particle engine that is flexible enough to enable me to design different effects/magic
let me know if you guys have recommendations.

How do we rotate the camera around x axis 360 degrees, without having the strange effect as in my video below?
Mine behaves exactly the same way spherical coordinates would, I'm using euler angles.
Tried googling, but couldn't find a proper answer, guessing I don't know what exactly to google for, googled 'rotate 360 around x axis', got no proper answers.

The video shows the difference between blender and my rotation:
