Member Function Documentation
const float* Dali::Vector3::AsFloat | ( | ) | const |
Returns the contents of the vector as an array of 3 floats.
The order of the values in this array are as follows: 0: x (or width, or r) 1: y (or height, or g) 2: z (or depth, or b)
- Since:
- 2.4, DALi version 1.0.0
- Returns:
- The vector contents as an array of 3 floats
- Note:
- inlined for performance reasons (generates less code than a function call)
float* Dali::Vector3::AsFloat | ( | ) |
Returns the contents of the vector as an array of 3 floats.
The order of the values in this array are as follows: 0: x (or width, or r) 1: y (or height, or g) 2: z (or depth, or b)
- Since:
- 2.4, DALi version 1.0.0
- Returns:
- The vector contents as an array of 3 floats
- Note:
- inlined for performance reasons (generates less code than a function call)
void Dali::Vector3::Clamp | ( | const Vector3 & | min, |
const Vector3 & | max | ||
) |
Clamps the vector between minimum and maximum vectors.
- Since:
- 2.4, DALi version 1.0.0
- Parameters:
-
[in] min The minimum vector [in] max The maximum vector
Vector3 Dali::Vector3::Cross | ( | const Vector3 & | other | ) | const |
Returns the cross produce of this vector and another vector.
The cross produce of two vectors is a vector which is perpendicular to the plane of the two vectors. This is great for calculating normals and making matrices orthogonal.
- Since:
- 2.4, DALi version 1.0.0
- Parameters:
-
[in] other The other vector
- Returns:
- The cross product
float Dali::Vector3::Dot | ( | const Vector3 & | other | ) | const |
Returns the dot product of this vector and another vector.
The dot product is the length of one vector in the direction of another vector. This is great for lighting, threshold testing the angle between two unit vectors, calculating the distance between two points in a particular direction.
- Since:
- 2.4, DALi version 1.0.0
- Parameters:
-
[in] other The other vector
- Returns:
- The dot product
const Vector2& Dali::Vector3::GetVectorXY | ( | ) | const |

- Since:
- 2.4, DALi version 1.0.0
- Returns:
- The length of the vector
float Dali::Vector3::LengthSquared | ( | ) | const |
Returns the length of the vector squared.
This is more efficient than Length() for threshold testing as it avoids the use of a square root.
- Since:
- 2.4, DALi version 1.0.0
- Returns:
- The length of the vector squared
void Dali::Vector3::Normalize | ( | ) |
Sets the vector to be unit length, whilst maintaining its direction.
