Are triangles OK in 3D modeling?

First off, in many cases trianglar are totally fine to use, so it is not like they are ”forbidden” to use when doing a 3D-model. The main reason for not using triangles according my experience are these: They do not subdivide in a smooth way. For object that are meant to deformed this is very important.

What are triangles in 3D modeling?

A triangular polygon is referred to as a tri or triangle, and is a simple three-sided polygon. It has exactly 3 vertices at its corners and 3 edges connecting those points. This is the smallest configuration required to make a polygonal face.

Are tris or quads better?

Quads. The answer is simple and it ends right there. It doesn’t depend on any factors, and modeling with triangles is almost never better. Even if you are exporting your model to a game engine (which will require conversion to triangles), it is almost always better to model with quads.

Why are triangles bad in 3d Modelling?

Ngons and triangles both cause issues when trying to smooth a model. The extra vertices and edges can cause some very strange bumpiness in the model that would otherwise not occur if the model was made up of quads.

What 3D shape is pyramid?

A pyramid is a polyhedron for which the base is a polygon and all lateral faces are triangles.

What are 3D triangular prism?

A triangular prism is a 3D polyhedron with three rectangular faces and two triangular faces. The 2 triangular faces are congruent to each other, and the 3 lateral faces which are in the shape of rectangles are also congruent to each other. Thus, a triangular prism has 5 faces, 9 edges, and 6 vertices.

Why are triangles used in 3D modeling?

Triangles also are very memory efficient and can be sorted, and rendered extremely fast when using Triangle Strips which only need 1 point to be stored for each additional triangle after the first. and Triangle Fans which is a special case of a Triangle Strip.

Are triangles Ngons?

On rendering, every ngon is subdivided into triangles or triangulated. And so are quads. Quads are also split into triangles. Technically every quad is made of two triangles.

Is it okay to have Ngons?

Ngons or quads, having enough polygons to allow deformation (and an even distribution of polygons for that matter) is always a good practice. Even distribution of polygons is a good modeling practice.
