IG::IGIntersection Structure

The functionality described in this article is not available in the Community SDK edition.
You should upgrade to Sim SDK edition to use it.

This data structure stores the result of an intersection (intersection point coordinates as well as normal and texture coordinates, intersected object and surface index, intersection mask) and has the following set of parameters:

surface Intersected surface number.
mask Intersection mask.
object Intersected object.
point Coordinates of the intersection point.
normal Normal of the intersection point.
texcoord Texture coordinates of the intersection point.
The IGIntersection structure is declared as follows:
Source code (C++)
struct IGIntersection
	int surface;
	unsigned int mask;
	Unigine::ObjectPtr object;
	Unigine::Math::Vec3 point;
	Unigine::Math::vec3 normal;
	Unigine::Math::vec4 texcoord;
