#include <coordTrans.h>

Inheritance diagram for glift::CoordTrans:

glift::GliftObject List of all members.

Detailed Description

CoordTrans - Encapsulates a 4x4 matrix transform that can be specified as an absolute or relative transform.

It is most commonly used to transform texture coordinates of the primitive to which a shader is applied.

 debug error

gutz::arrayo1f CoordTrans::apply (  const gutz::arrayw1f &  coord,
const gutz::arrayw1f &  divisor
) 
 

Homogeneous 4-vec

Make a relative transform if requested

Do the transform

No default necessary b/c already checked above that one of these is valid.

Make a relative transform if requested

Homogeneous 4-vec

Do the transform

Drop the 4th component (always 1.0)

vec2f CoordTrans::apply (  const gutz::vec2f &  coord,
const gutz::vec2f &  divisor
) 
 

Apply transform to 'coord'.

  • If 'm_relScale' or 'm_relBias' are true, the appropriate transform components are first divided by the corresponding component of the 'divisor' vector.
