LsgTransform * LsgTransform_create (  void   )  [related]

Allocate and initialize a transformation node. Returns: a new LsgTransform instance

void LsgTransform_init (  LsgTransform *  self  )  [related]

Constructor method for LsgTransform. Initialize the transformation to identity. Parameters: self  The instance variable

void LsgTransform_update (  LsgTransform *  self, float  now )  [related]

Update all children and recompute the bounding box. Parameters: self  The instance variable now  The current time

void LsgTransform_display (  LsgTransform *  self, LsgFrustum *  frustum )  [related]

Display all children with a transformed view frustum and changed OpenGL modelview matrix. Parameters: self  The instance variable frustum  The view frustum

int LsgTransform_collide (  LsgTransform *  self, Vertex  v, Vertex  nearest )  [related]

Compute collision with transformed children. Parameters: self  The instance variable v  Some vertex nearest  A buffer to store the nearest vertex to v that would collide with any child Returns: 1 if v after being transformed collides with at least one child, 0 otherwise
