Once again... Textures?

Ok, here it is. I started learning OpenGL about 6-7 months back, and i got to NeHe's 6th tutorial. Then i had to stop, because i couldnt get textures to work. So i learned DX. I thaught i would try OpenGL again, and im at lesson 6, and i am having the exact same problem. I think the problem is when im trying to either load or display my image. Here are the three functions that take care of that. Load Textures: int LoadTextures() { int Status=false; AUX_RGBImageRec *TextureImage[1]; memset(TextureImage, 0, sizeof(void *)*1); if(TextureImage[0]=LoadBMP("C:\\Damian\\PROGRAMMINGPROJECTS\\FireflyOpenGL\\Data\\Images\\File.bmp")) { Status=true; glGenTextures(1, &Texture[0]); glBindTexture(GL_TEXTURE_2D, Texture[0]); glTexImage2D(GL_TEXTURE_2D, 0,3,TextureImage[0]->sizeX, TextureImage[0]->sizeY, 0, GL_RGB, GL_UNSIGNED_BYTE, TextureImage[0]->data); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); } if(TextureImage[0]) { if(TextureImage[0]->data) { memset(TextureImage[0]->data, 0, sizeof(TextureImage[0]->data)); } memset(TextureImage[0], 0, sizeof(TextureImage[0])); } return(Status); } DrawGLScene: int GLDrawScene(GLvoid) //Draws the OpenGL Scene { glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); //Clear the Screen each frame //World Stuff glLoadIdentity(); //Load the Identity glTranslatef(-1.5f, 0.0f, -12.0f); //Drawing glRotatef(RotX, 1.0f, 0.0f, 0.0f); glRotatef(RotY, 0.0f, 1.0f, 0.0f); glRotatef(RotZ, 0.0f, 0.0f, 1.0f); glBindTexture(GL_TEXTURE_2D, Texture[0]); //Pyramid glBegin(GL_TRIANGLES); //Top Point(front) glTexCoord2f(0.5f, 0.0f); glVertex3f(0.0f, 1.0f, 0.0f); //Bottom Left hand corner(front) glTexCoord2f(0.0f, 1.0f); glVertex3f(-1.0f,-1.0f,1.0f); //Bottom Right Hand Corner(front) glTexCoord2f(1.0f, 1.0f); glVertex3f(1.0f, -1.0f,1.0f); //Top Point(Right) glTexCoord2f(0.5f, 0.0f); glVertex3f(0.0f, 1.0f, 0.0f); //Bottom Left hand corner(Right) glTexCoord2f(0.0f, 1.0f); glVertex3f(-1.0f,-1.0f,-1.0f); //Bottom Right Hand Corner(Right) glTexCoord2f(1.0f, 1.0f); glVertex3f(-1.0f, -1.0f,1.0f); //Top Point(back) glTexCoord2f(0.5f, 0.0f); glVertex3f(0.0f, 1.0f, 0.0f); //Bottom Left hand corner(back) glTexCoord2f(0.0f, 1.0f); glVertex3f(-1.0f,-1.0f, -1.0f); //Bottom Right Hand Corner(back) glTexCoord2f(1.0f, 1.0f); glVertex3f(1.0f, -1.0f,-1.0f); //Top Point(left) glTexCoord2f(0.5f, 0.0f); glVertex3f(0.0f, 1.0f, 0.0f); //Bottom Left hand corner(left) glTexCoord2f(0.0f, 1.0f); glVertex3f( 1.0f,-1.0f,-1.0f); //Bottom Right Hand Corner(left) glTexCoord2f(1.0f, 1.0f); glVertex3f(1.0f, -1.0f,1.0f); glEnd(); //World Stuff glLoadIdentity(); glTranslatef(1.5f, 0.0f, -12.0f); glRotatef(RotX, 1.0f, 0.0f, 0.0f); glRotatef(RotY, 0.0f, 1.0f, 0.0f); glRotatef(RotZ, 0.0f, 0.0f, 1.0f); //Cube glBegin(GL_QUADS); //Top glTexCoord2f(0.0f,0.0f); glVertex3f(-1.0f, 1.0f,1.0f); glTexCoord2f(1.0f,0.0f); glVertex3f( 1.0f, 1.0f,1.0f); glTexCoord2f(1.0f,1.0f); glVertex3f( 1.0f, 1.0f,-1.0f); glTexCoord2f(0.0f,1.0f); glVertex3f(-1.0f, 1.0f,-1.0f); //Front glTexCoord2f(0.0f,0.0f); glVertex3f(-1.0f,-1.0f, 1.0f); glTexCoord2f(1.0f,0.0f); glVertex3f( 1.0f,-1.0f, 1.0f); glTexCoord2f(1.0f,1.0f); glVertex3f( 1.0f, 1.0f, 1.0f); glTexCoord2f(0.0f,1.0f); glVertex3f(-1.0f, 1.0f, 1.0f); //Left glTexCoord2f(0.0f,0.0f); glVertex3f(-1.0f,-1.0f, 1.0f); glTexCoord2f(1.0f,0.0f); glVertex3f(-1.0f, 1.0f, 1.0f); glTexCoord2f(1.0f,1.0f); glVertex3f(-1.0f, 1.0f,-1.0f); glTexCoord2f(0.0f,1.0f); glVertex3f(-1.0f,-1.0f,-1.0f); //Bottom glTexCoord2f(0.0f,0.0f); glVertex3f(-1.0f,-1.0f, 1.0f); glTexCoord2f(1.0f,0.0f); glVertex3f( 1.0f,-1.0f, 1.0f); glTexCoord2f(1.0f,1.0f); glVertex3f( 1.0f,-1.0f,-1.0f); glTexCoord2f(0.0f,1.0f); glVertex3f(-1.0f,-1.0f,-1.0f); //Back glTexCoord2f(0.0f,0.0f); glVertex3f(-1.0f, 1.0f,-1.0f); glTexCoord2f(1.0f,0.0f); glVertex3f( 1.0f, 1.0f,-1.0f); glTexCoord2f(1.0f,1.0f); glVertex3f( 1.0f,-1.0f,-1.0f); glTexCoord2f(0.0f,1.0f); glVertex3f(-1.0f,-1.0f,-1.0f); //Right glTexCoord2f(0.0f,0.0f); glVertex3f( 1.0f, 1.0f, 1.0f); glTexCoord2f(1.0f,0.0f); glVertex3f( 1.0f, -1.0f, 1.0f); glTexCoord2f(1.0f,1.0f); glVertex3f( 1.0f, -1.0f,-1.0f); glTexCoord2f(0.0f,1.0f); glVertex3f( 1.0f, 1.0f,-1.0f); glEnd(); //Rotation RotX+=0.1f; RotZ+=0.2f; RotY+=0.3f; return(true); //Return Success } LoadBMP: AUX_RGBImageRec *LoadBMP(char *Filename) { FILE *File=NULL; if(!Filename) { return(NULL); } File=fopen(Filename, "r"); if(File) { fclose(File); return(auxDIBImageLoad(Filename)); } return(NULL); } Here is The specific problem: It doesnt display the actual texture. I tried removing the color, thinking it was overriding the picture or something, but it didnt work. If you want any other part of the code tell me. I would have come to you 2 days ago when i started having the problem, but i wanted to try to find it myself. P.S. Oh ya, and it also wont display anything but a screenshot of my desktop in Fullscreen mode if that helps. ______________________________ Quantum CEO of Quantum Rebound Software Website Up Soon [edited by - QReboundSoftware on August 9, 2003 9:20:32 AM]

And i dont have a business license. Its just sorta a virtual company per se.

if you have no business license, it is not a business, and you can''t be CEO.

while you may think it is great to pretend to run a company that doesn''t exist, it just makes everyone else think you are lame (except maybe the other 12-year-olds claiming to be CEOs).

Oi! Leave the kid alone!

I bet half of the ''adult'' companies are much the same. It has no legal standing, but all he means is that is his role and function. It''s all a bit of fun I''m sure, but wait and second... don''t we make computer GAMES?

12 eh? When I was 12, I learned 8086 assembler and learned how to program 13h video mode... THOSE were the days...

hahaha!

All bow to Krez!

So does that mean all I need to do to become a CEO is to make up a name of a company, and tell people about it?

in that case..
