Methods

void * _cPtr(Flag!"Dup" dup = No.Dup) nothrow

GType _getGType() static nothrow

GType _gType() @property nothrow

Triangle self() nothrowReturns `this`, for use in `with` statements.

graphene.triangle.Triangle alloc() static nothrowAllocates a new #graphene_triangle_t.

bool containsPoint(graphene.point3_d.Point3D p) nothrowChecks whether the given triangle `t` contains the point `p`.

bool equal(graphene.triangle.Triangle b) nothrowChecks whether the two given #graphene_triangle_t are equal.

float getArea() nothrowComputes the area of the given #graphene_triangle_t. Returns: the area of the triangle

bool getBarycoords(graphene.point3_d.Point3D p, out graphene.vec2.Vec2 res) nothrowComputes the [barycentric coordinates](http://en.wikipedia.org/wiki/Barycentric_coordinate_system) of the given point `p`.

void getBoundingBox(out graphene.box.Box res) nothrowComputes the bounding box of the given #graphene_triangle_t.

void getMidpoint(out graphene.point3_d.Point3D res) nothrowComputes the coordinates of the midpoint of the given #graphene_triangle_t.

void getNormal(out graphene.vec3.Vec3 res) nothrowComputes the normal vector of the given #graphene_triangle_t.

void getPlane(out graphene.plane.Plane res) nothrowComputes the plane based on the vertices of the given #graphene_triangle_t.

void getPoints(out graphene.point3_d.Point3D a, out graphene.point3_d.Point3D b, out graphene.point3_d.Point3D c) nothrowRetrieves the three vertices of the given #graphene_triangle_t and returns their coordinates as #graphene_point3d_t.

bool getUv(graphene.point3_d.Point3D p,  graphene.vec2.Vec2 uvA,  graphene.vec2.Vec2 uvB,  graphene.vec2.Vec2 uvC,  out  graphene.vec2.Vec2 res)

nothrowComputes the UV coordinates of the given point `p`.

void getVertices(out graphene.vec3.Vec3 a, out graphene.vec3.Vec3 b, out graphene.vec3.Vec3 c) nothrowRetrieves the three vertices of the given #graphene_triangle_t.

graphene.triangle.Triangle initFromFloat(float[] a, float[] b, float[] c) nothrowInitializes a #graphene_triangle_t using the three given arrays of floating point values, each representing the coordinates of a point in 3D space.

graphene.triangle.Triangle initFromPoint3d(graphene.point3_d.Point3D a,  graphene.point3_d.Point3D b,  graphene.point3_d.Point3D c)

nothrowInitializes a #graphene_triangle_t using the three given 3D points.

graphene.triangle.Triangle initFromVec3(graphene.vec3.Vec3 a =  null,  graphene.vec3.Vec3 b =  null,  graphene.vec3.Vec3 c =  null)

nothrowInitializes a #graphene_triangle_t using the three given vectors.
