◆ BoundingBoxSet()
| small3d::BoundingBoxSet::BoundingBoxSet |
( |
const std::vector< float > & |
vertexData, |
|
|
const Vec3 & |
scale, |
|
|
uint32_t |
subdivisions |
|
) |
| |
Constructor that creates a box set, constructed based on the vertex data that can be found in a Model.
- Parameters
-
| vertexData | The vertex data. Array of floats to be interpreted as an array of 4 component vertex coordinates. |
| scale | Scale applied to the vertexData before calculating boxes. |
| subdivisions | How many times to subdivide the initially one created bounding box, getting more accurate collision detection at the expense of performance. |
◆ contains()
| bool small3d::BoundingBoxSet::contains |
( |
const Vec3 |
point, |
|
|
const Vec3 |
thisOffset, |
|
|
const Mat4 |
thisRotation |
|
) |
| const |
Check if a point is inside any of the boxes.
- Parameters
-
| point | The point (as a vector) |
| thisOffset | The offset (location) of the box set |
| thisRotation | The rotation transformation of the box set |
- Returns
- True the point is inside a box, False if not.
◆ containsCorners()
| bool small3d::BoundingBoxSet::containsCorners |
( |
const BoundingBoxSet & |
otherBoxSet, |
|
|
const Vec3 |
thisOffset, |
|
|
const Mat4 |
thisRotation, |
|
|
const Vec3 |
otherOffset, |
|
|
const Mat4 |
otherRotation |
|
) |
| const |
Check any of the corners of another set of bounding boxes is inside any of the boxes of this set.
- Parameters
-
| otherBoxSet | The other box set |
| thisOffset | The offset (location) of this box set |
| thisRotation | The rotation transformation of this box set |
| otherOffset | The offset (location) of the other box set |
| otherRotation | The rotation transformation of the other box set |
- Returns
- True if a corner of the other bounding box set is contained in this set, False otherwise.
◆ getModels()
| std::vector< Model > small3d::BoundingBoxSet::getModels |
( |
| ) |
|
Get the bounding boxes in a set of Models that can be rendered.
- Returns
- The set of bounding boxes as Models
