H A DSpotShadow.java70 * calculates the Centroid of a 3d polygon
71 * @param poly The flatten 3d vertices coordinates of polygon, the format is like
73 * @param len The number of polygon vertices. So the length of poly should be len * 3.
103 * Extracts the convex hull of a polygon.
104 * @param points The vertices coordinates of polygon
105 * @param pointsLength The number of polygon vertices. So the length of poly should be len * 3.
106 * @param retPoly retPoly is at most the size of the input polygon
180 * @param poly1 The flatten 2d coordinates of polygon
182 * @param poly2 The flatten 2d coordinates of polygon

H A DSpotShadow.cpp24 // When the polygon is about 90 vertices, the penumbra + umbra can reach 270 rays.
25 // That is consider pretty fine tessllated polygon so far.
38 // For the whole polygon, the sum of all the deltas b/t normals is 2 * M_PI,
69 * For each polygon's vertex, the light center will project it to the receiver
144 * @param pointsLength the number of vertices of the polygon.
157 * @param pointsLength the number of vertices of the polygon.
159 * @return the number of points in the polygon 0 if no intersection
235 * @param polyLength The number of vertices of the polygon.
278 * Test whether a point is inside the polygon.
