Syntax

bool dtOverlapPolyPoly2D
(
    const float * polya,
    const int npolya,
    const float * polyb,
    const int npolyb
)

Remarks

Determines if the two convex polygons overlap on the xz-plane.

All vertices are projected onto the xz-plane, so the y-values are ignored.

Returns

True if the two polygons overlap.

Parameters

Parameter	Description
polya	Polygon A vertices. [(x, y, z) * npolya]
npolya	The number of vertices in polygon A.
polyb	Polygon B vertices. [(x, y, z) * npolyb]
npolyb	The number of vertices in polygon B.
