Member Function Documentation

void Obj::pos (  float  px, float  py, float  pz )

Sets position vector. Parameters: px  X component of position vector. py  Y component of position vector. pz  Z component of position vector. Reimplemented in AbsObj, and Light.

void Obj::setup (  float  px, float  py, float  pz, float  vx, \float  vy, float  vz, float  ux, float  uy, float  uz )

Set all parameters in one go. Calls pos, view, up. See also: pos view up Parameters: px  X component of position vector. py  Y component of position vector. pz  Z component of position vector. vx  X component of view vector. vy  Y component of view vector. vz  Z component of view vector. ux  X component of up vector. uy  Y component of up vector. uz  Z component of up vector.

Here is the call graph for this function:

void Obj::up (  float  ux, float  uy, float  uz )

Sets up vector. Parameters: ux  X component of up vector. uy  Y component of up vector. uz  Z component of up vector.

void Obj::view (  float  vx, float  vy, float  vz )

Sets view vector. Parameters: vx  X component of view vector. vy  Y component of view vector. vz  Z component of view vector.

Member Data Documentation

Vec4 Obj::vpos

The vector for the position of the object. 3D only.

Vec4 Obj::vstrafe

The vector for the strafe direction. Cross product of up and view.

Vec4 Obj::vup

The vector for the up direction of the object. Needed for cameras etc. 3D only.

Vec4 Obj::vview

The vector for the view of the the object. 3D only. By view we mean the point that the vector is looking at.
