May 10, 2017 · I have these 3 points: A= [30,0,0]; B= [0,40,0]; C= [0,0,10]; How can I draw a triangle which has the 3 nodes by A,B,C in 3 dimensional space?

To create a triangulation object, use the triangulation function with input arguments that define the triangulation's points and connectivity. TR = triangulation(T,x,y) creates a 2-D triangulation representation with the point coordinates specified as column vectors x and y.

Feb 9, 2024 · Creating 3D shapes in MATLAB can be done using various functions depending on the type of 3D visualization you want. For a 3D square (which is actually a cube) or a 3D triangle (which could be interpreted as a tetrahedron or a triangular prism), you can use the ‘ patch’ or ‘surf’ functions to draw the faces of these shapes.

trimesh(TO) plots the mesh defined by a 3-D triangulation or delaunayTriangulation object. trimesh(___,Name,Value) specifies options using one or more name-value arguments. For example, trimesh(T,x,y,"LineWidth",2) sets the edge width to 2 points.

Jan 31, 2015 · I would like to draw different triangles by using MATLAB shown in the figure below. Suppose that I have 3 vectors V1=[1 1 1] , V2=[-1 1 1] , v3=[-2 -2 -2] . How can I draw triangle with these vectors in 3D?

Mar 11, 2019 · We will explain how to define a 3D model in terms of its geometry and which kind of information is required for plotting such models with Matlab. We will learn how to define a 3D Model and the appropriate Matlab functions to show it in your screen.

Sep 1, 2015 · Step #1 - Drawing the triangle. The best thing to create that triangle is to use the patch function. patch takes in a set of vertices as well as the order of how you traverse these vertices, and optionally a face colour. As such, the first bit of code is this: vert = [0 1 0; 1 0 0; 0 0 1]; patch('Vertices', vert, 'Faces', 1:3, 'FaceColor', 'cyan');

Represent 2-D or 3-D triangulation data as a triangulation object, and use object functions to compute geometric quantities. You can visualize the triangulation and work with STL files to read and write triangulation data. This topic contains background information on triangulation and introduces the triangulation class.

This example shows how to create a variety of 3-D plots in MATLAB®. The mesh function creates a wireframe mesh. By default, the color of the mesh is proportional to the surface height. The surf function is used to create a 3-D surface plot. The surfl function creates a surface plot with colormap-based lighting.
