Hye , i am kind of new to open gl and i cant get texture mapping to work properly. Instead of textured polygons i get a pixely mess. I load my textures with a function i wrote similar to NEHE''s loadbmp in chapter 6. Any ideas of whats wrong? //Some code unsigned int ogl_textures[MAX_TEXTURES]; int ogl_tex_no = 0; typedef AUX_RGBImageRec OGL_IMAGE; int map[MAP_X_SIZE*MAP_Y_SIZE] = {1,1,1,1, 1,0,0,1, 1,0,0,1, 1,0,0,1, 1,1,1,1}; OGL_IMAGE *ogl_load_bitmap(LPSTR file_name) { FILE *fp; fp=fopen(file_name,"rb"); if(fp==NULL) { return NULL; } else { fclose(fp); return auxDIBImageLoad(file_name); } } //========================================================== void ogl_init_texturing(void) { glEnable(GL_TEXTURE_2D); glGenTextures(MAX_TEXTURES,ogl_textures); ogl_tex_no = 0; } //========================================================== int ogl_bind_texture(OGL_IMAGE *image) { if(ogl_tex_no < MAX_TEXTURES) { glBindTexture(GL_TEXTURE_2D,ogl_textures[ogl_tex_no]); glTexImage2D(GL_TEXTURE_2D,0,3,image->sizeX,image->sizeY,0,GL_RGB,GL_UNSIGNED_BYTE,&image->data); glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_LINEAR); glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_LINEAR); ogl_tex_no++; return 1; } return 0; } //=========================================================== void ogl_switch_texture(int num) { glBindTexture(GL_TEXTURE_2D,ogl_textures[num]); } //=========================================================== //A bit of initialzation ogl_init_texturing(); if((game_textures[0]=ogl_load_bitmap("rock.bmp")) == NULL){exit(1);} if((game_textures[1]=ogl_load_bitmap("grass.bmp"))== NULL){exit(1);} if((ogl_bind_texture(game_textures[0]))==0){ exit(1);} if((ogl_bind_texture(game_textures[1]))==0){ exit(1);} //=============================================== void draw_map(void) { int dx,dy,col; float sp=1.0; glColor3ub(255,255,255); glBegin(GL_QUADS); for(dy=0;dy
