Define Documentation

#define LsgTransform_clean (  self   )     LsgGroup_clean(&(self)->super)

Clean all children. Reuse parent implementation.

#define LsgTransform_destroy (  self   )     LsgGroup_destroy(&(self)->super)

Destructor method for LsgTransform. Reuse parent implementation.

Function Documentation

LsgTransform* LsgTransform_create (  void   )

Allocate and initialize a transformation node.

void LsgTransform_init (  LsgTransform *  self  )

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

void LsgTransform_update (  LsgTransform *  self, float  now )

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

void LsgTransform_display (  LsgTransform *  self, LsgFrustum *  frustum )

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 )

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
