ios - Can I union multiple transparent SCNShape objects? -


i'm adding multiple transparent scnshape objects arscnsceneview scene.

  • these shapes based on user input , should overlap.
  • they flat shapes made uibezierpath on same plane
  • shapes has transparent, user can see camera input behind

the problem overlapping shapes visible, , i'd show single shape - union of shapes.

failed approaches:

  • putting under same node , use parent opacity.
  • merging uibezier paths.
  • blend modes
  • transparency modes
  • drawing using primitive triangles instead of uibezierpath

wanted vs current results

you have @ vectorboolean swift library deal boolean operations union looking for. haven't tried myself have heard things it.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
