This is mostly used for rendering meshes that have multiple separate triangle sets, know as submeshes. How to show the wireframe?Ī mesh renderer can have multiple materials. Unity's default capsule, cube, and sphere, shaded vs. Typically that's not feasible for realtime performance, so the surfaces will always appear jagged to some degree. If the triangles appear small enough – no larger than a single pixel – then you won't notice the approximation. Curved or round surfaces can only be approximated by using many small triangles. The triangles form the surface of whatever the mesh represents.Īs triangles are flat and have straight edges, they can be used to perfectly visualize flat and straight things, like the faces of a cube.
#Unity 3d virtual world generator plus#
It contains at least a collection of vertices that define points in 3D space, plus a set of triangles – the most basic 2D shapes – that connect these points. So what is a mesh? Conceptually, a mesh is a construct used by the graphics hardware to draw complex stuff. Even screen effects are rendered with a mesh. It could be a sprite, UI element, or particle system, for which Unity uses meshes as well. It could be a procedurally generated mesh. It could be a 3D model exported from another program. If you want to visualize something in Unity, you use a mesh. Beneath complex appearance lies simple geometry. This tutorial has been made for Unity 5.0.1 and up. Constructing a Fractal provides an introduction to coroutines. This tutorial assumes that you are familiar with the basics of Unity scripting. In this tutorial we'll create a simple grid of vertices and triangles. Use a coroutine to analyze their placement.
