Aug 10, 2015 · I have a list of vertices location in a STL file (mesh.vertices), but I don`t have indices order (mesh.triangles), how can I draw this mesh in Unity? Thank you. Saw this in unity forums while ago, non-indexed mesh, just set indices to 0, 1, 2, 3, 4, 5, 6.... and.

Jan 23, 2014 · Now, I need to, dynamically / programmatically, create new vertices on the gameobject. The number of vertices are dynamic, and a… I’ve created a plane in Blender with the exact dimensions I need and imported it to Unity.

Apr 4, 2016 · Here’s the simple code in UnityScript. There’s no errors, but it doesn’t show anything on the screen. // Create the vertices. var Vertices = Array(); Vertices[0] = Vector3(0, 0, 0); Vertices[1] = Vector3(1, 0, 0); Vertices[2] = Vector3(0, 1, 0); Vertices[3] = Vector3(1, 1, 1); // Create the UVs. var UVs = Array(); UVs[0] = Vector2(0, 1);

May 9, 2012 · I’m new to Unity and am wanting to be able to create meshes, and modify them, through scripting. The basic code for simply create a mesh with random vertices is below. No mesh appears when I run it. The only thing I’ve tried is attaching it to an empty gameObject, or a mesh like a cube.

Nov 9, 2015 · I would recommend using a procedural mesh to create the geometry you need as you need it. The basics aren't too hard, it's just a matter of constructing the Mesh object from it's base components given some vertices. Here's an example of constructing a 3d quadrilateral:

Mar 31, 2024 · // This Unity script demonstrates how to create a Mesh (in this case a Cube) purely through code. // Simply, create a new Scene, add this script to the Main Camera, and run. //Create a 'Cube' mesh... //I have used 16 vertices (4 vertices per side). //This is because I want the vertices of each side to have separate normals.

Jul 30, 2014 · I already did this in C#, but for some reason it doesn't work in UnityScript/JS. I declared the mesh like this: var mesh = new Mesh(); I added the vertices, triangles, Uvs that I used in C# and than I called the functions Optimize() …

Jan 27, 2019 · First we need to create data structures to hold our vertices and triangles. Vertices are coordinates, since we are now dealing with 3D space we create a Vector3 array (Vector3[]) and call it “vertices”. I am declaring them as public so we can see and change them in the inspector in Unity later on.

The number of vertices in the Mesh is changed by assigning a vertex array with a different number of vertices. Note that if you resize the vertex array then all other vertex attributes (normals, colors, tangents, UVs) are automatically resized too.

May 27, 2015 · You can use this to read & modify any information you want about mesh assets in your project, or even create whole new meshes procedurally. You can access and iterate over mesh information like this: void AssignBoneColors(Mesh mesh) { Color32[] colors = mesh.colors32; // Ready an array large enough for all vertices if the mesh didn't already ...
