Ph.D., a postdoctoral fellow with the University of California Los Angeles’s math department. The only way to form triangles in the figure I drew, Erikkson-Bisque says, is if the top vertex ...

This math is a sizeable step up from vectors ... Here a single green triangle is tessellated into many more baby triangles... The vertex processing is done via 3 separate shaders (see code ...

The tetrahedron has 3 triangles connecting at each vertex, resulting in 4 total triangles, while the octahedron has 4 triangles connecting at each vertex (8 total triangles), and the icosahedron ...

As an art form, tessellation is particularly rich in mathematics ... for the first tiling below, each vertex is composed of the point of a triangle (3 sides), a hexagon (6), another triangle ...

Look for arcs inside each vertex. The same number of arcs indicate equal angles. Different numbers of arcs indicate different angles. To identify the symmetry of a triangle: Count how many ways ...
