Write the algorithm in pseudocode for scan-converting (filling in the interior) of an axis-aligned right triangle (the base is aligned with the x-axis and the orthogonal leg is aligned with the y-axis).

Expert Solution

Answer.

Step 1

Pseudo code:

Declare

Read x //Base axis

Read y //Orthogonal leg

Read color //Color to fill the interior

//Defining scan_converting

Function scan_converting(Triangle T1, Color color)

//Filling interior based on pixel

For each pixel P1 at (x,y)

If (Inside (T1,P1))

setPixel(x,y,color)

End If

End Loop

End

Step 2

Explanation:

The setPixel() fills the interior with the given color.
To fill the interior, first one need to find the edges of triangle, the Inside() method finds the edge.
The Triangle class is responsible to draw the triangle with the x and y coordinate values.

Thank you.

1. Write pseudocode for the algorithm using iteration (looping). Envision an algorithm that when given any positive integer n, it will print out the sum of the squares from 1 to n. For example given 3 the algorithm will print 14 (because 1 + 4 + 9 =14) You can use multiplication denoted as * in your solution and you do not have to define it (For example. 3*3=9) For example if n is 6 it will print: The sum...

Write a Python program that: Create the algorithm in both flowchart and pseudocode forms for the following requirements: Reads in a series of positive integers, one number at a time; and Calculate the product (multiplication) of all the integers less than 25, and Calculate the sum (addition) of all the integers greater than or equal to 25. Use 0 as a sentinel value, which stops the input loop. [ If the input is 0 that means the end of the input list. ]...

Write in c++ as simple as possible In a right triangle, the square of the length on one side is equal to the sum of the squares of the lengths of the other two sides. Write a program that prompts the user to enter the length of three sides of the tringle (as doubles) and the outputs a message indication whether the triangle is a right triangle. You should split this into two functions (but only one .cpp file). One function is main()...

Write class Hypotenuse that calculates the length of the hypotenuse of a right triangle and return to HypotenuseTest class. The lengths of the other two sides are given by the user by using HypotenuseTest class and send into Hypotenuse class. Hypotenuse class should take two arguments of type double and return the hypotenuse as a double into HypotenuseTest’s Main method. Finally, the HypotenuseTest class displays the hypotenuse side of a triangle.
