GL_TEXTURE_2D making problems for lighting? - opengl

Question

I wanted to ask you about texture and lighting.
I am using a 3ds Object in OpenGL, and a BITMAP texture. It is working perfectly. When I use lighting it didn't reflect the light. While I was searching I just commented the line: glEnable(GL_TEXTURE_2D); and the Texture was gone but lighting works!
Is there any opportunity that I can leave TEXTURE and also add lighting? Why is this happening? Anyone any idea?
EDITED
this is in INIT() function
void initialize(){
glEnable(GL_DEPTH_TEST); // We enable the depth test (also called z buffer)
glPolygonMode(GL_FRONT_AND_BACK, GL_FILL); // Polygon rasterization mode (polygon filled)
glEnable(GL_TEXTURE_2D); // This Enable the Texture mapping
glEnable(GL_LIGHTING);
glEnable(GL_LIGHT0);
glEnable(GL_NORMALIZE);
// Light model parameters:
// -------------------------------------------
GLfloat lmKa[] = {0.0, 0.0, 0.0, 0.0 };
glLightModelfv(GL_LIGHT_MODEL_AMBIENT, lmKa);
glLightModelf(GL_LIGHT_MODEL_LOCAL_VIEWER, 1.0);
glLightModelf(GL_LIGHT_MODEL_TWO_SIDE, 0.0);
// -------------------------------------------
// Spotlight Attenuation
GLfloat spot_direction[] = {1.0, -1.0, -1.0 };
GLint spot_exponent = 30;
GLint spot_cutoff = 180;
glLightfv(GL_LIGHT0, GL_SPOT_DIRECTION, spot_direction);
glLighti(GL_LIGHT0, GL_SPOT_EXPONENT, spot_exponent);
glLighti(GL_LIGHT0, GL_SPOT_CUTOFF, spot_cutoff);
GLfloat Kc = 1.0;
GLfloat Kl = 0.0;
GLfloat Kq = 0.0;
glLightf(GL_LIGHT0, GL_CONSTANT_ATTENUATION,Kc);
glLightf(GL_LIGHT0, GL_LINEAR_ATTENUATION, Kl);
glLightf(GL_LIGHT0, GL_QUADRATIC_ATTENUATION, Kq);
// -------------------------------------------
// Lighting parameters:
GLfloat light_pos[] = {0.0f, 5.0f, 5.0f, 1.0f};
GLfloat light_Ka[] = {1.0f, 0.5f, 0.5f, 1.0f};
GLfloat light_Kd[] = {1.0f, 0.1f, 0.1f, 1.0f};
GLfloat light_Ks[] = {1.0f, 1.0f, 1.0f, 1.0f};
glLightfv(GL_LIGHT0, GL_POSITION, light_pos);
glLightfv(GL_LIGHT0, GL_AMBIENT, light_Ka);
glLightfv(GL_LIGHT0, GL_DIFFUSE, light_Kd);
glLightfv(GL_LIGHT0, GL_SPECULAR, light_Ks);
// -------------------------------------------
// Material parameters:
GLfloat material_Ka[] = {0.5f, 0.0f, 0.0f, 1.0f};
GLfloat material_Kd[] = {0.4f, 0.4f, 0.5f, 1.0f};
GLfloat material_Ks[] = {0.8f, 0.8f, 0.0f, 1.0f};
GLfloat material_Ke[] = {0.1f, 0.0f, 0.0f, 0.0f};
GLfloat material_Se = 20.0f;
glMaterialfv(GL_FRONT_AND_BACK, GL_AMBIENT, material_Ka);
glMaterialfv(GL_FRONT, GL_DIFFUSE, material_Kd);
glMaterialfv(GL_FRONT_AND_BACK, GL_SPECULAR, material_Ks);
glMaterialfv(GL_FRONT_AND_BACK, GL_EMISSION, material_Ke);
glMaterialf(GL_FRONT_AND_BACK, GL_SHININESS, material_Se);
}
this is the DISPLAY() function (I am using QT)
void pointGL(){
if(change)
{
ThreeDModels objectClass;
objectClass.SpaceShip();
change = false;
}
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glLoadIdentity();
glPushMatrix();
glScalef(0.05, 0.05, 0.05);
ThreeDModels objectiModel;
objectiModel.objectCreation(l_index);
glPopMatrix();
}
Method which other method for Loading 3ds object and add Texture
void ThreeDModels::SpaceShip()
{
Load3DS(&objecti, "C:/Users/Documents/3DModelRendering/3DModels/Spaceship/spaceship.3ds");
int a = LoadBitmap2("C:/Users/Documents/3DModelRendering/3DModels/Spaceship/spaceshiptexture.bmp");
}
void ThreeDModels::objectCreation(int l_index)
{
glBegin(GL_TRIANGLES); // glBegin and glEnd delimit the vertices that define a primitive (in our case triangles)
for (l_index = 0; l_index<objecti.polygons_qty; l_index++)
{
//----------------- FIRST VERTEX -----------------
// Texture coordinates of the first vertex
glTexCoord2f(objecti.mapcoord[objecti.polygon[l_index].a].u,
objecti.mapcoord[objecti.polygon[l_index].a].v);
// Coordinates of the first vertex
glVertex3f(objecti.vertex[objecti.polygon[l_index].a].x,
objecti.vertex[objecti.polygon[l_index].a].y,
objecti.vertex[objecti.polygon[l_index].a].z); //Vertex definition
//----------------- SECOND VERTEX -----------------
// Texture coordinates of the second vertex
glTexCoord2f(objecti.mapcoord[objecti.polygon[l_index].b].u,
objecti.mapcoord[objecti.polygon[l_index].b].v);
// Coordinates of the second vertex
glVertex3f(objecti.vertex[objecti.polygon[l_index].b].x,
objecti.vertex[objecti.polygon[l_index].b].y,
objecti.vertex[objecti.polygon[l_index].b].z);
//----------------- THIRD VERTEX -----------------
// Texture coordinates of the third vertex
glTexCoord2f(objecti.mapcoord[objecti.polygon[l_index].c].u,
objecti.mapcoord[objecti.polygon[l_index].c].v);
// Coordinates of the Third vertex
glVertex3f(objecti.vertex[objecti.polygon[l_index].c].x,
objecti.vertex[objecti.polygon[l_index].c].y,
objecti.vertex[objecti.polygon[l_index].c].z);
}
glEnd();
}

Answer 1

I found the Answer guys:
glTexEnvf(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_REPLACE); was in the LoadBitmap() method, just removing this one, and it worked ;D
