raytracing - Ray-tracer loop ordering -


Tracer and found an unexpected problem. If I write the two main ends of the re-tracer, the people responsible for the image pixel, like this: 

 for  (int y = 0; y & lt; image.getWidth (); Y ++) {For (int x = 0; x & lt; image.getHyight (); x ++) {

I get this distorted image (actually , The image of Facebook scoops, in any way, is more than the actual, but the issue is that the code has many reflective areas with many types of scanlines (which are actually small)

However, if I make a small change, then: 

 for  (int y = 0; y & lt ; Image.getHyight (); y ++) {for (int x = 0; X & lt; image.getWidth (); x ++) {  
 As an attraction Works as it can be seen below:  
  
  getHyight ,  getWidth  gives me the height and width of the image Here's some more code that I believe can be helpful: 
 
  rayview = {{float (x), float (y), -1000.0 f}, {0.0 f , 0.0 F, 1.0 F}}  
 
 La Part camera location, the other thing is that I do not know why it makes any input is appreciated. If another code is necessary to evaluate the problem, just ask.

The problem is that although you change the order of the for-loop, you are not changing the index . You should try: 

 for  (int x = 0; x & lt; image.getWidth (); x ++) {for (int y = 0; y & lt; image .getHyight (); y ++) {

Compare two snippets with that post.

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
