how can I make solid AND wire frame cube ?

2

if u can use glut call glutSolidCube(1) for solid and glutWireCube(1) for wire unitcube

3

If you wanna draw your entire scene in wireframe you can use


glPolygonMode( GL_FRONT_AND_BACK, GL_LINE );

before your draw calls.

Hm… I am fighting with cube - left side must be always in the same place and right side can go up or down like in train or like in arm - my previous subject - so now I have found that code - two cubes, one has got angle 45 degrees and second - 45 degrees:


glPushMatrix();
   glTranslatef(0, 0, -70.0f);
   glTranslatef (-1.0, 0.0, 0.0);
   glRotatef (45, 0.0, 0.0, 1.0);
   glTranslatef (1.0, 0.0, 0.0);
   glPushMatrix();
   glScalef (2.0, 0.4, 1.0);
   glutWireCube (1.0);
   glPopMatrix();
   
   glPushMatrix();
   glTranslatef(0, 0, -70.0f);
   glTranslatef (-1.0, 0.0, 0.0);
   glRotatef (-45, 0.0, 0.0, 1.0);
   glTranslatef (1.0, 0.0, 0.0);
   glPushMatrix();
   glScalef (2.0, 0.4, 1.0);
   glutWireCube (1.0);
   glPopMatrix();

Result: http://img101.imageshack.us/i/75891671.jpg/ - this is what I need - figure < but it must be also solid so I have changed code:


glPushMatrix();
   glTranslatef(0, 0, -70.0f);
   glTranslatef (-1.0, 0.0, 0.0);
   glRotatef (45, 0.0, 0.0, 1.0);
   glTranslatef (1.0, 0.0, 0.0);
   glPushMatrix();
   glScalef(0.02, 1, 0.02);
   glutSolidCube(50);	
   glPopMatrix();
   
   glPushMatrix();
   glTranslatef(0, 0, -70.0f);
   glTranslatef (-1.0, 0.0, 0.0);
   glRotatef (-45, 0.0, 0.0, 1.0);
   glTranslatef (1.0, 0.0, 0.0);
   glPushMatrix();
   glScalef(0.02, 1, 0.02);
   glutSolidCube(50);
   glPopMatrix();

but the final result is: http://img225.imageshack.us/i/57953116.jpg/
left side first cube is in one place, and left side second cube is in different place - why ? It is figure X and I want figure < like previous.

What do u get if u just replace the glutWireCube to glutSolidCube in the first code like this.


glPushMatrix();
   glTranslatef(0, 0, -70.0f);
   glTranslatef (-1.0, 0.0, 0.0);
   glRotatef (45, 0.0, 0.0, 1.0);
   glTranslatef (1.0, 0.0, 0.0);
   glPushMatrix();
   glScalef (2.0, 0.4, 1.0);
   glutSolidCube (1.0);
   glPopMatrix();
   
   glPushMatrix();
   glTranslatef(0, 0, -70.0f);
   glTranslatef (-1.0, 0.0, 0.0);
   glRotatef (-45, 0.0, 0.0, 1.0);
   glTranslatef (1.0, 0.0, 0.0);
   glPushMatrix();
   glScalef (2.0, 0.4, 1.0);
   glutSolidCube (1.0);
glPopMatrix();

Interesting - I have got that what I wanted - figure <, but when I have changed:


glutSolidCube (1.0);

to


glutSolidCube (50.0);

I have got figure X - what can I do ?

7

Why 50.0 instead of 1.0?

I can stay glutSolidCube (1.0);
and use glScalef (15.0, 0.4, 1.0); - but the result is the same - bad
