hello!

i am currently making my own ogl engine. in blitz3d, but using openGL :)

my question is: how to rotate sprites?

[they shouldn't face to the camera. they should be parallel to the near/far clip plane]

thats what i use for the camera:

	glLoadIdentity
	glScalef cam\zoom#, cam\zoom#, 1
	glRotatef cament\rx#, 1, 0, 0
	glRotatef 180 - cament\ry#, 0, 1, 0
	glRotatef cament\rz#, 0, 0, 1
	glTranslatef cament\x#, -cament\y#, -cament\z#

thats what i use for meshes

			glPushMatrix
			glTranslatef -e\x#, e\y#, e\z#
			glScalef e\sx#, e\sy#, e\sz#
			glRotatef e\rx#, 1, 0, 0
			glRotatef e\ry#, 0, 1, 0
			glRotatef e\rz#, 0, 0, 1
......

thank you for any help :)
