def FXVec4f.plane(vec); end

Instance Method Details

#*(n) ⇒ Object

Returns a new FXVec4f instance obtained by memberwise multiplication of this vector’s elements by the scalar n.



58
 
# File 'rdoc-sources/FXVec4f.rb', line 58

def *(n); end

#+(other) ⇒ Object

Returns a new FXVec4f instance obtained by memberwise addition of the other FXVec4f instance with this one.



44
 
# File 'rdoc-sources/FXVec4f.rb', line 44

def +(other); end

#-(other) ⇒ Object

Returns a new FXVec4f instance obtained by memberwise subtraction of the other FXVec4f instance from this one.



51
 
# File 'rdoc-sources/FXVec4f.rb', line 51

def -(other); end

#-@ ⇒ Object

Returns a new FXVec4f instance which is the negation of this one.



37
 
# File 'rdoc-sources/FXVec4f.rb', line 37

def -@(); end

#/(n) ⇒ Object

Returns a new FXVec4f instance obtained by memberwise division of this vector’s elements by the scalar n. Raises ZeroDivisionError if n is identically zero.



66
 
# File 'rdoc-sources/FXVec4f.rb', line 66

def /(n); end

#==(other) ⇒ Object

Return true if this vector is equal to other.



77
 
# File 'rdoc-sources/FXVec4f.rb', line 77

def ==(other); end

#[](index) ⇒ Object

Returns the element at index, where index is 0, 1, 2 or 3. Raises IndexError if index is out of range.



28
 
# File 'rdoc-sources/FXVec4f.rb', line 28

def [](index); end

#[]=(index, value) ⇒ Object

Set the element at index to value and return value. Raises IndexError if index is out of range.



34
 
# File 'rdoc-sources/FXVec4f.rb', line 34

def []=(index, value); end

#clamp(lo, hi) ⇒ Object

Clamp the values of this vector between limits lo and hi.



92
 
# File 'rdoc-sources/FXVec4f.rb', line 92

Return the cross product of this vector and other.



74
 
# File 'rdoc-sources/FXVec4f.rb', line 74

def cross(other); end

#crosses?(a, b) ⇒ Boolean

Return true if edge a-b crosses plane

Returns:

  • (Boolean) 


136
 
# File 'rdoc-sources/FXVec4f.rb', line 136

def crosses?(a, b); end

#distance(p) ⇒ Object
