## Detailed Description

A 4D vector with "float" components.

Definition at line 305 of file vector4.h.

## Constructor & Destructor Documentation

csVector4::csVector4 | ( |  | ) | `[inline]`

Make a new vector.

The vector is not initialized. This makes the code slightly faster.

Definition at line 312 of file vector4.h.

csVector4::csVector4 | ( | const float & | m | ) | `[inline]`

Make a new initialized vector.

Creates a new vector and initializes it to m*<1,1,1,1>. To create a vector initialized to the zero vector, use csVector4(0)

Definition at line 319 of file vector4.h.

csVector4::csVector4 | ( | float | ix,
|  | float | iy,
|  | float | iz = `0`,
|  | float | iw = `1` |
| ) |  |  | `[inline]`

Make a new vector and initialize with the given values.

Definition at line 322 of file vector4.h.

csVector4::csVector4 | ( | const csVector4 & | v | ) | `[inline]`

Copy Constructor.

Definition at line 326 of file vector4.h.

csVector4::csVector4 | ( | const csVector4T< float > & | v | ) | `[inline]`

Copy Constructor.

Definition at line 329 of file vector4.h.

csVector4::csVector4 | ( | const csVector3 & | v | ) | `[inline]`

Convert from a three-component vector. w is set to 1.

Definition at line 332 of file vector4.h.
