progress indicator raytracer

To create a progress indicator in a raytracer using C++, you can follow these steps:

1. Initialize the required variables: Start by initializing the variables that you will need for the progress indicator. For example, you might need a variable to store the total number of rays to be traced and another variable to keep track of the current ray being traced.

2. Calculate the progress: Once you have the necessary variables, you can calculate the progress of the ray tracing process. This can be done by dividing the current ray number by the total number of rays and multiplying the result by 100 to get a percentage value.

3. Display the progress: To show the progress to the user, you can output the calculated percentage value to the console or any other desired output stream. You can use the "cout" statement in C++ to display the progress.

4. Update the progress: As the ray tracing process continues, you should update the progress indicator to reflect the current state. This can be done by incrementing the variable storing the current ray number and recalculating the progress using the formula mentioned in step 2.

5. Repeat steps 3 and 4 until the ray tracing is complete: Keep updating and displaying the progress until all the rays have been traced. This will provide the user with a visual representation of the progress being made.

By following these steps, you can create a progress indicator in a raytracer using C++. Remember to adapt the code to fit your specific raytracer implementation and user interface requirements.
