default |
Trivial constructor, the vector is NOT initialized
|
inlineexplicit |
Construct a vector all of whose components have the given value.
|
inline |
Constructor with four arguments, e.g. Vec4f v(1,2,3,4);.
|
inline |
Constructor with array argument, e.g. float a[4]; Vec4f v(a);.
Conversion constructor.
|
inlineexplicit |
Construct a vector all of whose components have the given value, which may be of an arithmetic type different from this vector's value type.
Type conversion warnings are suppressed.

|
inline |
Return a reference to itself after the exponent has been applied to all the vector components.
|
inline |
"this" vector gets initialized to [x, y, z, w], calling v.init(); has same effect as calling v = Vec4::zero();
|

True if no Nan or Inf values are present.
|

True if an Inf is present in this tuple.
|
inlineinherited |
True if a Nan is present in this tuple.
|
inlineinherited |
True if all elements are exactly zero.
|
inline |
