Matrix3D()

Crea una nueva matriz unitaria

Method Detail

scale

void scale(float f)

Aplica un factor de escala a todas las dimensiones.

Parameters:

f - Factor de escala.

scale

void scale(float xf,
           float yf,
           float zf)

Scale along each axis independently.

Parameters:

xf - Factor de escala sobre el eje X.

yf - Factor de escala sobre el eje Y.

zf - Factor de escala sobre el eje Z.

translate

void translate(float x,
               float y,
               float z)

Translate the origin

yrot

void yrot(double theta)

rotate theta degrees about the y axis

xrot

void xrot(double theta)

rotate theta degrees about the x axis

zrot

void zrot(double theta)

rotate theta degrees about the z axis

mult

void mult(Matrix3D rhs)

Multiplica la matriz dada por la matriz de rotaciones.

Parameters:

rhs -

unit

void unit()

Reinicializa a una matriz unitaria.

transform

void transform(float[] v,
               int[] tv,
               int nvert)

Transform nvert points from v into tv. v contains the input coordinates in floating point. Three successive entries in the array constitute a point. tv ends up holding the transformed points as integers; three successive entries per point

toString

public java.lang.String toString()

Obtiene las coordenadas en forma de cadena de caracteres.

Overrides:
