Although 2D graphics may be used to draw 3D objects, any simulation of depth and shading must be created by the artist using standard drawing tools, color fills and gradients. The vertices (end points) of the triangles are assigned X-Y-Z and RGB values, which are used to compute light reflections for shading and rendering. Some applications create multiple models with different amounts of triangles and use the best one depending on distance. Among regular figures (equal length sides, equal angles), there are just three shapes that tessellate in this way: squares, equilateral triangles and. The more triangles used to represent a surface, the more realistic the rendering, but the more computation is required.ĭepending on the object's distance from the camera, triangles may be discarded at the time they are rendered. All surfaces, both curved and straight, are turned into triangles either at the time they are first created or in real time when they are rendered. We conclude: There are three regular tessellations of the plane: by triangles, by squares, by hexagons. In surface modeling and solid modeling, the method used to represent 3D objects as a collection of triangles or other polygons. How many sides can a regular tessellation have Regular tessellation A regular polygon with more than six sides has a corner angle larger than 120 (which is 360/3) and smaller than 180 (which is 360/2) so it cannot evenly divide 360.
