IIndexedPolygon

Represents an indexed polygon in 3D space. The polygon is defined using indices referencing the various attributes (e.g., position, texture coordinates, normals) provided in an external vertex data.

open fun base(vertexData: IVertexData): Matrix44

isConvex

open fun isConvex(vertexData: IVertexData): Boolean

Determines if the polygon defined by the given vertex data is convex.

isPlanar

open fun isPlanar(vertexData: IVertexData, eps: Double = 0.01): Boolean
