[Plib-users] transforming a sgSphere each frame ?

[Oliver B. <sh...@ih...>]

for a frustum cull I need to transform a sgSphere each frame by a
matrix  but  If I use the orthoXform then it gets changed each frame ?
how can I avoid this ?

the sphere::getCentre  how do I use that also It returns a pointer to
a sgfloat   but I cant make it equal to a sgVec3   and If I make it
equal to a float *   then use it like

variable[0]   variable[1]   variable[2]    for the x y and z it
contains rubish ...


thanks,
