Order does Matter
Click to check: Incorrect.
📗 [1 points] Consider the standard Z-buffer (only distance comparisons), and small triangles (with different solid colors, no transparency, and different depths or distances to the camera) all fit in the same one pixel.
➩ At most triangles can be write to the Z-Buffer.
➩ At least triangles can be write to the Z-Buffer.
➩ At most triangles can provide the color (average if more than one) to the pixel.
➩ At least triangles can provide the color to the pixel.
Click to check: Incorrect.
📗 [1 points] When we perform lighting in the fragment shader, the normal vector is passed as a varying variable. The values of the variable at the three vertices are , , . What is the value of the variable for the pixel at the center of triangle? .
Click to plot your vector: if it is correct (direction and magnitude), it will be green.
📗 [1 points] A sphere is lit by a single directional light source where the light is shining downwards. The sphere is made of purely diffuse material. The brightest point of the sphere is at its top. Which of the following will affect the position of the brightest point.
Still at the Top
