I try to use Newton as collision detection engine. But my simple test doesn't work. I have 2 intersecting trimesh objects but NewtonCollisionCollide returns that there is no collisions between them. What's wrong?
- Code: Select all
procedure TForm1.NewtonTest(Sender: TObject);
const
Min: array[0..2] of Single = (-10, -10, -10);
Max: array[0..2] of Single = ( 10, 10, 10);
var
World: PNewtonWorld;
Coll1, Coll2: PNewtonCollision;
Face: array[0..2] of TPoint;
Contacts, Normals, Penetration: array[0..2] of TVector3f;
begin
World := NewtonCreate(nil, nil);
NewtonSetWorldSize(World, @Min[0], @Max[0]);
Coll1 := NewtonCreateTreeCollision(World, nil);
NewtonTreeCollisionBeginBuild(Coll1);
Face[0].x := 0; Face[0].y := 0; Face[0].z := 0;
Face[1].x := 5; Face[1].y := 0; Face[1].z := 0;
Face[2].x := 5; Face[2].y := 5; Face[2].z := 0;
NewtonTreeCollisionAddFace(Coll1, 3, @Face[0], SizeOf(TPoint), 1);
NewtonTreeCollisionEndBuild(Coll1, 0);
Coll2 := NewtonCreateTreeCollision(World, nil);
NewtonTreeCollisionBeginBuild(Coll2);
Face[0].x := 2; Face[0].y := -2; Face[0].z := -1;
Face[1].x := 2; Face[1].y := 2; Face[1].z := -1;
Face[2].x := 2; Face[2].y := 0; Face[2].z := 1;
NewtonTreeCollisionAddFace(Coll2, 3, @Face[0], SizeOf(TPoint), 1);
NewtonTreeCollisionEndBuild(Coll2, 0);
ShowMessage(IntToStr(NewtonCollisionCollide(World, 3,
Coll1, @IdentityMatrix4f[0][0],
Coll2, @IdentityMatrix4f[0][0],
@Contacts[0][0], @Normals[0][0], @Penetration[0][0]))); //it shows 0
NewtonDestroy(World);
end;

collirion trees in 1.53 need more than one face

In my program (not in the test one) every mesh consist of at least 12 triangles. But program still doesn't work.
