Method Detail

dSafeNormalize3

public static boolean dSafeNormalize3(DVector3 a)

dSafeNormalize4

public static boolean dSafeNormalize4(DVector4 a)

dNormalize3

public static void dNormalize3(DVector3 a)

Potentially asserts on zero vec.

dNormalize4

public static void dNormalize4(DVector4 a)

Potentially asserts on zero vec.

dPlaneSpace

public static void dPlaneSpace(DVector3 n,
                               DVector3 p,
                               DVector3 q)

given a unit length "normal" vector n, generate vectors p and q vectors that are an orthonormal basis for the plane space perpendicular to n. i.e. this makes p,q such that n,p,q are all perpendicular to each other. q will equal n x p. if n is not unit length then p will be unit length but q wont be.
