INSIDE - Is a vertex or point inside a circum circle, etc. of a triangulated model inCircum determine whether or not a vertex is inside a circum circle inCircumTri determine whether or not a vertex is inside a circum circle of a triangle in3Vertices determine whether or not a vertex is inside triangle (v1,v2,v3) inTri determine whether or not a vertex is inside a triangle Function Prototypes: int inCircum (float x, float y, float xc, float yc, float rs); int inCircumTri (float x, float y, Tri *t); int in3Vertices (float x, float y, Vertex *v1, Vertex *v2, Vertex *v3); int inTri (float x, float y, Tri *t); inCircum: Input: x x-coordinate of vertex y y-coordinate of vertex xc x-coordinate of center of circumcircle yc y-coordinate of center of circumcircle rs radius^2 of circumcircle Returns: 1 if x,y inside of circumcircle 0 otherwise Notes: A vertex exactly on the edge of a circumcircle is taken as being outside inCircumTri: Input: x x-coordinate of vertex y y-coordinate of vertex t pointer to Tri Returns: 1 if x,y inside of circumcircle of a triangle 0 otherwise Notes: A vertex exactly on the edge of a circumcircle is taken as being outside in3Vertices: Input: x x-coordinate of vertex y y-coordinate of vertex v1 pointer to first Vertex v2 pointer to second Vertex v3 pointer to third Vertex Returns: 1 if x,y inside of v1,v2,v3 0 otherwise Notes: A vertex exactly on an edge of the triangle is taken as being inside inTri: Input: x x-coordinate of vertex y y-coordinate of vertex t pointer to Tri Returns: 1 if x,y inside a triangle 0 otherwise Notes: A vertex exactly on the edge of a triangle is inside Author: Dave Hale, Colorado School of Mines, 06/04/91
