📗 [1 points] Which of the following THREE.Object3D can cast shadow, i.e. if obj.castShadow = true works? THREE.PointLight THREE.SpotLight THREE.Mesh THREE.Camera THREE.WebGLRenderer None of the above.
📗 [1 points] Which types of textures work properly as THREE.MeshStandardMaterial.envMap? THREE.CubeTexture THREE.CanvasTexture THREE.VideoTexture THREE.DepthTexture THREE.TextureLoader None of the above.
📗 [1 points] Which of the following material properties work the best with environment maps envMap for a THREE.MeshStandardMaterial? Select the best one so that the resulting object looks like a mirror. roughness = 0, metalness = 1 roughness = 1, metalness = 0 roughness = 0.5, metalness = 0.5 shininess = 0 shininess = 100 None of the above.
📗 [1 points] Which of the following triangles should be culled before shading? A triangle outside of the camera frustum A triangle farther than the far plane A triangle with normals pointing to the opposite direction of the camera A triangle with normals pointing to the direction of the camera A triangle farther than the near plane None of the above.
📗 [1 points] Suppose there are only three triangles inside the camera frustum: triangle 1 has vertices 3, 4, 5 units away from the camera; triangle 2 has vertices 0, 1, 2 units away from the camera; triangle 3 has vertices 1, 1, 1 units away from the camera. Which of these triangles should be drawn first if painter's algorithm is used? Select all possible answers. 1 2 3 Intersection between 2 and 3, need to cut them Intersection between 1 and 2, need to cut them None of the above.
📗 [1 points] Suppose Z-Buffer algorithm is used and the current frame buffer at [x, y] has color c = rgb(200, 0, 0) and depth z = 10, and a new pixel with color c = rgb(0, 200, 0) and depth z = 5 is added. What is the new color and z value at [x, y]? c = rgb(0, 200, 0), z = 5 c = rgb(100, 100, 0), z = 7.5 c = rgb(200, 0, 0), z = 10 c = rgb(100, 100, 0), z = 5 c = rgb(100, 100, 0), z = 10 None of the above.
