- What role does the reflection vector play in computer graphics? You must include at least two instances to back up your claim.What use does the reflection vector serve in computer graphics? Provide at least two instances to substantiate your assertion.Write a code that can be used to plot a 3D graph where x & y are between -5 to 5 and z is defined by the following equation. “z=4x4y - 3x3y2 + x”
- What is the purpose of the reflection vector in computer graphics? Expound on at least two examples to back up your claim.Computer Science For an image represented by a given large 3d numpy array, use numpy to get a neighborhood filter using the mean of the pixels. For example, look through each of the image’s 3×3 window of pixels and replace outlier pixels with the mean value of the others in the 3×3 window. Set the resulting pixel value to be the mean value of a pixel and its eight neighbors. For pixels on an edge, use the mean value of the pixel and its five neighbors. For pixels on corners, use the mean value of the pixel and its three neighbors. If you loop over every pixel then you must store your input and output arrays separatelyWrite the java program problem in below image -
