Rotate a particle system
- by Blueski
Languages / Libraries in use: C++, OpenGL, GLUT
Okay, here's the deal.
I've got a particle system which shoots out alpha blended textures to produce a flame. The system only keeps track of very basic things such as, time alive, life, xyz and spread.
The direction in which the flames are currently moving in is purely based on other things which are going on in my code ( I assume ).
My goal however, is to attach the flame to the camera (DONE) and have the flame pointing in the direction my camera is facing (NOT WORKING).
I've tried glRotate for both x,y,z and I can't get it to work properly.
I'm currently using gluLookAt to move the camera, and get the flame to follow the XYZ of the camera by calling glTranslatef(camX, camY - offset, camZ);
Any suggestions on how I can rotate the direction of the flame with the camera would be greatly appreciated.
Heres an image of what I've got: http://i.imgur.com/YhV4w.png
Notes: Crosshair depicts where camera is facing
if I turn the camera, flame doesn't follow the crosshair
