Oritened Bounding Box(OBB)
The OBB is similar to the AABB but the bounding box has the same direction as Sprite3D. so it's collistion detection more precise than AABB
| bool containPoint | ( | const Vec3 & | point | ) | const |
Check if the point is contained in the bounding box.
The specified point. Return true when the point is contained in the bounding box, otherwise return false.
| local containPoint | ( | local | point | ) |
Check if the point is contained in the bounding box.
The specified point. Return true when the point is contained in the bounding box, otherwise return false.
| void getCorners | ( | Vec3 * | verts | ) | const |
Get Obb's corners.
The Corners vertices array. Face to the obb's -z direction verts[0] : left top front verts[1] : left bottom front verts[2] : right bottom front verts[3] : right top front
face to the obb's z direction verts[4] : right top back verts[5] : right bottom back verts[6] : left bottom back verts[7] : left top back
| local getCorners | ( | local | verts | ) |
Get Obb's corners.
The Corners vertices array. Face to the obb's -z direction verts[0] : left top front verts[1] : left bottom front verts[2] : right bottom front verts[3] : right top front
face to the obb's z direction verts[4] : right top back verts[5] : right bottom back verts[6] : left bottom back verts[7] : left top back
| bool intersects | ( | const OBB & | box | ) | const |
Tests whether this bounding box intersects the specified bounding object.
The specified bounding box. Return true when two OOBBS intersect, otherwise return false.
| local intersects | ( | local | box | ) |
Tests whether this bounding box intersects the specified bounding object.
The specified bounding box. Return true when two OOBBS intersect, otherwise return false.
| void transform | ( | const Mat4 & | mat | ) |
Transforms the obb by the given transformation matrix.
The transform matrix.
| local transform | ( | local | mat | ) |
Transforms the obb by the given transformation matrix.
The transform matrix.
