My texture keeps showing up white on screen - opengl

Question

I cant seem to load an image and use it as a texture to my program: the image is 512*512 in size and i dont know what im doing wrong, can someone help me?
Main function:
int main(int argc, char** argv)
{
glutInit (&argc, argv);
glutInitWindowSize (800,600);
glutInitDisplayMode (GLUT_SINGLE | GLUT_RGB);
glutCreateWindow ("CS248 GLUT example");
glutDisplayFunc (display);
glutReshapeFunc (reshape);
glutMainLoop ();
return 0;
}
The display function:
void display() {
glClear(GL_COLOR_BUFFER_BIT);
glEnable(GL_TEXTURE_2D);
glColor3f(1.0f,1.0f,1.0f);
texture = LoadTexture("space.bmp");
glBindTexture(GL_TEXTURE_2D, texture);
glBegin(GL_QUADS);
glTexCoord2f(0.0, 0.0); glVertex3f(-20.0,-20.0,0);
glTexCoord2f(0.0, 1.0); glVertex3f(-20.0, 20.0, 0.0);
glTexCoord2f(1.0, 1.0); glVertex3f(20.0, 20.0, 0.0);
glTexCoord2f(1.0, 0.0); glVertex3f(20.0, -20.0, 0.0);
glEnd();
glFlush();
}
So, i call here the loadtexture function to an GLuint texture, this way:
GLuint LoadTexture( const char* texture )
{
GLuint textureID = SOIL_load_OGL_texture( texture, SOIL_LOAD_AUTO, SOIL_CREATE_NEW_ID, SOIL_FLAG_MIPMAPS );
glGenTextures(1,&textureID);
glBindTexture( GL_TEXTURE_2D, textureID );
glTexParameteri( GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR );
glTexParameteri( GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR );
glTexParameteri( GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT );
glTexParameteri( GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT );
return textureID;
}
Reshape function:
void reshape(GLsizei w, GLsizei h) {
glViewport(0, 0, 800, 600);
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
glOrtho(-20.0f, 20.0f, -20.0f, 20.0f, -20.0f, 20.0f);
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
}
Includes,etc:
#include <glut.h>
#include <SOIL.h>
GLuint texture;

Answer 1

GLuint textureID = SOIL_load_OGL_texture( texture, SOIL_LOAD_AUTO, SOIL_CREATE_NEW_ID, SOIL_FLAG_MIPMAPS );
glGenTextures(1,&textureID);
SOIL_load_OGL_texture creates an OpenGL texture object. Generating a new one (which is what glGenTextures does) after already creating one is counter-productive.
Ditch that line, and you'll probably be OK.
However, you should not be reloading the texture on every display. You should be creating that texture once, during initialization, then just using the texture with a glBindTexture call.
