Polygon count

So, this geometry object will consist of vertices along with a face.

Your next problem is not too tough. The PolygonGeometry function has been extended to include a location.

This process is naturally called triangulation, usually we use the existing vertices as the polygon when performing triangulation.

Now, modify the program to use a radius to make the polygon generated larger or smaller.

The word, tessellate is from the Greek word Tessella, which means a small stone in a mosaic.

A regular polygon is one that has equal angles and equal length sides.

By multiplying the original point by the radius, this expands or contracts these points around the origin.

Your draw function is called polygon draw function in the code. It takes as an input the number of sides desired.

I'll provide you the basic trigonometry function for generating the polygons points.

There's one more useful thing we can add to our polygon creator, changing the radius of the polygon.

Instead the only place to add edges is here and here, giving the only possible triangulation.

Montral. When it comes to making surfaces the GPU understands only triangles.

But these were the early days of this technology, and it wasn't really proven yet.

The backfaces here and here do not need to be rendered.

Your job is to save the vertices, then use these vertices in a loop that generates the faces for the polygon.

There are a number of ways to do this, here's mine.

We have these maquettes scanned into the computer at very high resolution enormous polygonal count.

We measure complexity and fidelity of data in terms of polygonal count.

Once upon a time some older graphics hardware from the 1980's supported objects such as polygons or even more complex objects.
