Couple o' questions/problems
number 1)
my crosshair is pissing me off! =P mmkay, i have it centered in the screen and make it move with forward backward side/side, but i cant get it to stay in the center of screen no matter what, i want it to like move with the mouse etc, so i was wondering if i could use somthing similar to the, getCursorpos and setCursorpos, heres my current code for the crosshair,
void Crosshair()
{
glBindTexture(GL_TEXTURE_2D, texture[4]);
glTranslatef(chx,chy,chz-0.12f);
glBegin(GL_QUADS);
glColor3f(1.0f,1.0f,1.0f);
glTexCoord2f(0.0f, 0.0f); glVertex3f(-0.003f, -0.003f, 0.003f);
glTexCoord2f(0.003f, 0.0f); glVertex3f( 0.003f, -0.003f, 0.003f);
glTexCoord2f(0.003f, 0.003f); glVertex3f( 0.003f, 0.003f, 0.003f);
glTexCoord2f(0.0f, 0.003f); glVertex3f(-0.003f, 0.003f, 0.003f);
glEnd();
}
as you can see, it wont do any mouse movements...
my 2nd question/problem is, i need a good tut on billboarding for my sun/moon im making
and finally, is there a better way to make an object orbit arround some x,y,z coords/other objects that translatef...
thx 9in advance, dirtypope
1/ setup a 2d orthogonal window (info in faq http://www.frii.com/~martz/oglfaq/ ) draw the crosshairs in the middle
2/ nate miller (google) has a demo + info
3/ not really to rotate around a point u must first translate the point to (0,0,0) + then perform the translation. u can do this with a cobination of glTranslate(..) + glRotate or glMultMatrix() or glLoadMatrix. the last 2 require u to do the maths

go to glvelocity.gamedev.net and then in to the code archhive there is a sampel of showing a crosshair
with source of course!

i dont think i set up the 2dortho window correctly, cuz i did it how that page said to draw 2d controlls to a 3d app, and when i did that, my textures all like started mixing and rotating when i moved etc etc, looked like my app was on some strong acid or somthing =P is there any tuts that go more in detail on that subject?
