📗 [1 points] Given a triangle where vertex \(1\) is with color , vertex \(2\) is with color , vertex \(3\) is with color . Colors are given as RGB values from \(0\) to \(1\). The color at the point is .
Click to check: Incorrect.
📗 [1 points] Consider a cone that points upwards. Specify the axis-angle rotation to point the cone towards a different direction as in the picture on the right: \(\begin{bmatrix} r \\ x \\ y \\ z \end{bmatrix}\) = with cone.rotateOnAxis(new THREE.Vector3(x, y, z), r);.
Note: if you think \(\begin{bmatrix} r \\ x \\ y \\ z \end{bmatrix}\) = \(\begin{bmatrix} \pi \\ 1 \\ 1 \\ 0 \end{bmatrix}\), enter or round to 4 decimal places.
Use to apply the rotation to the cone on the left.
📗 [1 points] Perform vertex splitting so that the triangle on the left is and the triangle on the right is .
Left: vertices: , indices: , colors:
Right: vertices: , indices: , colors:
Use to apply the new vertices to the picture on the left.
📗 [1 points] Which of the following information are used in environment mapping, that is, which things does environment mapping use to determine where to look up in the texture image?

📗 [1 points] Suppose a \(32 \times 32\) texture uses mip-mapping with 6 levels (images with sizes \(32 \times 32\), \(16 \times 16\), \(8 \times 8\), \(4 \times 4\), \(2 \times 2\), \(1 \times 1\)). What is the largest number of color values in the mip-map and interpolate them to get the result?
