Syntax

void pscale3 (
  const Pvec3  ∗scale_vector,  /∗ (I) Scale factor vector ∗/

  Pmatrix3      matrix         /∗ (O) Transformation matrix ∗/
)

Data Structures

typedef struct {
    Pfloat     delta_x;    /∗ delta x value ∗/
    Pfloat     delta_y;    /∗ delta y value ∗/
    Pfloat     delta_z;    /∗ delta z value ∗/
} Pvec3;
 
typedef Pfloat Pmatrix3[4][4];

Description

pscale3 creates a three-dimensional (4 x 4) homogeneous transformation matrix that performs the specified scaling.  The returned matrix can be passed to functions that require transformation matrices as input, such as the pset_local_tran3, pset_global_tran3, and pcompose_matrix3 functions.  To store a matrix in a structure element, you must pass it to the pset_local_tran3 or pset_global_tran3 function.
