copied!<p>Hey this is my first post on stackflow so bare with me. i have been attempting to use OpenGL with C++ lately and i have come a cross a problem when trying to render a cube with lighting...but it doesn't appear i believe this is due to some kinda of clipping error but i have no clue :( any help would be appreciated.</p> <p>here is my code...</p> <p>the initialization function... </p> <pre><code>glMatrixMode(GL_MODELVIEW); glLoadIdentity(); glEnable(GL_DEPTH_TEST); glEnable(GL_COLOR_MATERIAL); glEnable(GL_LIGHTING); //Enable lighting glEnable(GL_LIGHT0); //Enable light #0 glEnable(GL_LIGHT1); //Enable light #1 glEnable(GL_NORMALIZE); //Automatically normalize normals </code></pre> <p>and here is the draw code</p> <pre><code> glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glTranslatef(0.0f, 0.0f, -8.0f); //Add ambient light GLfloat ambientColor[] = {0.2f, 0.2f, 0.2f, 1.0f}; //Color (0.2, 0.2, 0.2) glLightModelfv(GL_LIGHT_MODEL_AMBIENT, ambientColor); //Add positioned light GLfloat lightColor0[] = {0.5f, 0.5f, 0.5f, 1.0f}; //Color (0.5, 0.5, 0.5) GLfloat lightPos0[] = {4.0f, 0.0f, 8.0f, 1.0f}; //Positioned at (4, 0, 8) glLightfv(GL_LIGHT0, GL_DIFFUSE, lightColor0); glLightfv(GL_LIGHT0, GL_POSITION, lightPos0); //Add directed light GLfloat lightColor1[] = {0.5f, 0.2f, 0.2f, 1.0f}; //Color (0.5, 0.2, 0.2) //Coming from the direction (-1, 0.5, 0.5) GLfloat lightPos1[] = {-1.0f, 0.5f, 0.5f, 0.0f}; glLightfv(GL_LIGHT1, GL_DIFFUSE, lightColor1); glLightfv(GL_LIGHT1, GL_POSITION, lightPos1); glRotatef(Rotation, 0.0f, 1.0f, 0.0f); glColor3f(1.0f, 1.0f, 0.0f); glBegin(GL_QUADS); //Front glNormal3f(0.0f, 0.0f, 1.0f); //glNormal3f(-1.0f, 0.0f, 1.0f); glVertex3f(-1.5f, -1.0f, 1.5f); //glNormal3f(1.0f, 0.0f, 1.0f); glVertex3f(1.5f, -1.0f, 1.5f); //glNormal3f(1.0f, 0.0f, 1.0f); glVertex3f(1.5f, 1.0f, 1.5f); //glNormal3f(-1.0f, 0.0f, 1.0f); glVertex3f(-1.5f, 1.0f, 1.5f); //Right glNormal3f(1.0f, 0.0f, 0.0f); //glNormal3f(1.0f, 0.0f, -1.0f); glVertex3f(1.5f, -1.0f, -1.5f); //glNormal3f(1.0f, 0.0f, -1.0f); glVertex3f(1.5f, 1.0f, -1.5f); //glNormal3f(1.0f, 0.0f, 1.0f); glVertex3f(1.5f, 1.0f, 1.5f); //glNormal3f(1.0f, 0.0f, 1.0f); glVertex3f(1.5f, -1.0f, 1.5f); //Back glNormal3f(0.0f, 0.0f, -1.0f); //glNormal3f(-1.0f, 0.0f, -1.0f); glVertex3f(-1.5f, -1.0f, -1.5f); //glNormal3f(-1.0f, 0.0f, -1.0f); glVertex3f(-1.5f, 1.0f, -1.5f); //glNormal3f(1.0f, 0.0f, -1.0f); glVertex3f(1.5f, 1.0f, -1.5f); //glNormal3f(1.0f, 0.0f, -1.0f); glVertex3f(1.5f, -1.0f, -1.5f); //Left glNormal3f(-1.0f, 0.0f, 0.0f); //glNormal3f(-1.0f, 0.0f, -1.0f); glVertex3f(-1.5f, -1.0f, -1.5f); //glNormal3f(-1.0f, 0.0f, 1.0f); glVertex3f(-1.5f, -1.0f, 1.5f); //glNormal3f(-1.0f, 0.0f, 1.0f); glVertex3f(-1.5f, 1.0f, 1.5f); //glNormal3f(-1.0f, 0.0f, -1.0f); glVertex3f(-1.5f, 1.0f, -1.5f); glEnd(); SwapBuffers(hDC); Sleep (1); </code></pre> <p>any help will be appreciated </p> <p><strong>Edit one</strong><br> after following the advice of Keith i attempted to use the gluLookAt like this...</p> <pre><code>void gluLookAt ( 10.0 , 10.0 , 10.0 , 1.5, -1.0, 1.5, 0.0, 0.0, 1.0 ); </code></pre> <p>but i get an error</p> <p>|74|error: variable or field `gluLookAt' declared void|</p> <p>Final edit<br> thanks for your help everyone...it turned out i fail :( i hadn't declared the translation...or the perceptive..along with other crucial components...but i got it all working :D and thanks to Keith i no how to control the camera</p>
