Hi all. I was wondering if it is possible to take the text in Lesson 14 and make it spin with the spinning axis being in the middle. I''ve tried: glTranslate, then a glRotate, then calling the list, but then the rotation is around the start of the first object of the list Any help... Thx in advance Nexus --------------- Gaming is Life ---------------

Maybe this will help:

glPushMatrix();
glRotatef(x,0,1,0);

// draw the object you want to rotate around its axis

glPopMatrix();

thx for reply.

I got my push and pop, for Matrices and Attribs

First of all, i''ll need to know how to rotate an object around it own middlle? How

You have to rotate then translate.

static float Angle = 0.0f;
Angle += 0.3f;
CLAMP(Angle, 0.0f, 360.0f);

glPushMatrix();
glRotatef(Angle, 0, 1, 0);
glTranslate(Position.X, Position.Y, Position.Z);
RenderText();
glPopMatrix();

OK thx Ultima.

So I just have to tranlsate to the middle of the object after rotation?

I just downloaded lesson 14 and it rotates in the middle? Whats your look like? Is it going in a big circle and not staying center? Let me know, post your rotate/translate code, and I''ll be able to help you better.

LOL, yeah I know, I thought it didn''t. The problem I now have, is, how do I know how far to translate on the axisses to get the middle, the z axis is obviuios ( half of the width), but... on the X and Y, how would I know the middles, especially if u want to change the text dynamically. My guess is using the GLYPHMETRICSFLOAT struct u send with it when u cr8 the outlines, but it''s an array of values, and how does it work anyway? :|

I had this working but for some unrelated problems that were screwing it up and I ended up junking the rotation code.

I can''t recall right now exactly how I did it but I think I remember using the sine of the rotation angle...

If I redo that code I will post it here.
