Hello again ,
my merging problems are getting solved one after the other but something
seems to be a little strange to me :
I m trying to combine my merge technique with a flatshadematerial and
here s my issue :
// i create an empty mesh :
mesh = new TriangleMesh3D(new ColorMaterial(), [], []) ;
if i do :
var t : Sphere = new Sphere(new FlatShadeMaterial(light, 0xFF00FF)) ;
mesh.addChild(s) ;
everything if fine , the shader works properly
but if i do :
var t : Sphere = new Sphere(new FlatShadeMaterial(light, 0xFF00FF)) ;
mesh.geometry.vertices =
mesh.geometry.vertices.concat(t.geometry.vertices) ;
mesh.geometry.faces = mesh.geometry.faces.concat(t.geometry.faces) ;
to copy the geometry directly into my container without a child relationship
only half of the sphere is visible. The rest is totally black
( i dont have this problem with a color or simple wireframe material )
So maybe someone can tell me what am i doing wrog that brakes the shader ?
( my sphere is Y rotating in loop )
Thank you !
