Unigine::bvec4 Struct

Header:#include <UnigineMathLib.h>

This class represents a vector of 4 byte (unsigned char) components. This vector is used for vertex color parameters.

bvec4 Class

Members


bvec4()

Default constructor. Produces a zero vector.

bvec4(const bvec4 & v)

Constructor. Initializes the vector by copying a given source vector.

Arguments

  • const bvec4 & v - Source vector.

bvec4(unsigned char x, unsigned char y, unsigned char z, unsigned char w)

Constructor. Initializes the vector using given unsigned char values.

Arguments

  • unsigned char x - X component of the vector.
  • unsigned char y - Y component of the vector.
  • unsigned char z - Z component of the vector.
  • unsigned char w - W component of the vector.

bvec4(const vec4 & v, float scale)

Constructor. Initializes the vector using a given vec4 source vector and a scale multiplier.

Arguments

  • const vec4 & v - Source vector.
  • float scale - Scale.

explicit bvec4(unsigned char v)

Constructor. Initializes the vector using a given scalar value: x=v, y=v, z=v, w=v.

Arguments

  • unsigned char v - Scalar.

explicit bvec4(const vec4 & v)

Constructor. Initializes the vector using a given vec4 source vector.

Arguments

Constructor. Initializes the vector using a given ivec4 source vector.

Arguments

  • const ivec4 & v - Source vector.

explicit bvec4(const unsigned char * v)

Constructor. Initializes the vector using a given pointer to the array of unsigned char elements: x=v[0], y=v[1], z=v[2], w=v[3].

Arguments

  • const unsigned char * v - Pointer to the array of unsigned char elements.

void set(unsigned char x_, unsigned char y_, unsigned char z_, unsigned char w_)

Arguments

  • const unsigned char * val - Pointer to the array of unsigned char elements.

void set(unsigned char val)

Sets the vector components equal to specified scalar value: x=val, y=val, z=val, w=val.

Arguments

  • unsigned char val - Scalar value.

void set(const bvec4 & val)

Sets the vector equal to the specified vector.
