function
Geometry::Helper::getCornerIndices
| public |
| const corner_t * getCornerIndices( | const side_t | side ) |
Return the indices of the corners for the requestedside.
Defined in Geometry/BoxHelper.h:32
function
Geometry::Helper::getNormal
| public |
| const Vec3f & getNormal( | const side_t | side ) |
Return the normal for the requestedside.
Defined in Geometry/BoxHelper.h:35
function
Geometry::Helper::splitUpBox
| public |
| std::vector< Box_f > splitUpBox( | const Box_f & | box, |
| unsigned int | partsX, | |
| unsigned int | partsY, | |
| unsigned int | partsZ | |
| ) |
Create new boxes by splitting up a box along x/y/z axis.
Parameters
- box
- Box that will be used for splitting
- partsX
- number of resulting boxes along x-axis
- partsY
- number of resulting boxes along y-axis
- partsZ
- number of resulting boxes along z-axis
Returns
Container with the new boxes
Defined in Geometry/BoxHelper.h:46
function
Geometry::Helper::splitBoxCubeLike
| public |
| std::vector< Box_f > splitBoxCubeLike( | const Box_f & | box ) |
Split up a box once along up to three axis such that the resulting boxes are getting cube-like (when repeating this splitting). A box is cube-like if extentMax / extentMin <= sqrt(2).
Parameters
- box
- Box that will be used for splitting
Returns
Container with the new boxes
Defined in Geometry/BoxHelper.h:56
function
Geometry::Helper::getTransformedBox
| public |
| Box_f getTransformedBox( | const Box_f & | box, |
| const Matrix4x4f & | matrix | |
| ) |
Take a box and transform it by applying a transformation matrix to the corners. The resulting box will be axis-aligned.
Parameters
- box
- Box whose corners will be used
- matrix
- Transformation matrix
Returns
Axis-aligned box including the transformed corners

function
Geometry::Helper::createOrthogonal
| public |
| template< typename value_t > | ||
| _Vec2 < value_t > createOrthogonal( | const _Vec2 < value_t > & | vector ) |
Return a vector that is orthogonal to a given vector.
Parameters
- vector
- Any two-dimensional input vector
Returns
Vector that is orthogonal to and has the same length as the input vector

Parameters
- vector
- Normalized three-dimensional input vector
Returns
