An example of environment mapping: a silvered SGI O2 computer reflecting an environment map of the interior of a cafe. ping has been used to make the back and side walls more interesting. All the objects are reflected in the floor. How could you at any point apply a Naive Bayes classifier to the undertaking and assess it? Depict the methodology, including how you would appraise the boundaries. [3 marks] (b) You choose to involve accuracy and review rather than precision as the assessment metric for this assignment. This reflection is achieved by duplicating all of the geometry, upside-down, under the floor, and making the floor partially transparent. The close-up shows the reflection of the red ball, along with a circular "shadow" of the ball. This shadow is, in fact, a polygonal approximation to a circle drawn on the floor polygon and bears no relationship to the lights whatsoever. You may need to look at the version of these images on the Lab's website to see the images more clearly and in colour. Environment mapping Your partner needs to recruit two additional human annotators to re-mark your preparing information. For what reason could this be really smart, how might you measure arrangement in this undertaking, and how about this work on your classifier in any capacity? (Figure is another clever idea which makes polygon scan conversion images look more realistic. In environment mapping we have a texture map of the environment which can be thought of as wrapping completely around the entire scene (you could think of it as six textures on the six inside faces of a big box). The environment map itself is not drawn, but if any polygon is reflective then the normal to the polygon is found at each pixel (this normal is needed for Gouraud shading anyway) and from this, and a vector pointing to the eye, the appropriate point (and therefore colour) on the environment map can be located. You may note that finding the correct point on the environment map is actually a simple (and easily optimised) piece of ray tracing.
