When I first saw this, I did what most software developers normally, do. Unless you are an experienced Python/Numpy expert, you will probably spit your coffee when looking a the definition above. We first list the different vertices of the cube as a Numpy array of coordinates.
#CREATE 3DOBJECT FROM PHOTO BLENDER CODE#
Now that we have taken the definitions out of the way, the code snippet makes much more sense. As explained earlier faces can have different shapes, but during our exercise, we will only use triangular faces. Simple right?Ī Vertex Normal is a vector that points in the direction that a face points to.Ī mesh is a collection of vertices, edges and faces that describe the shape of a 3D object. An edge is a line that connects two vertices. The code above doesn’t explicitly mention edges, however, I think it is important to mention it for completeness.
I don’t know about you, but for me, it is already complicated enough with 3 edges. You could have a quadrilateral face or even a face with more than 4 edges. However, don’t think that a triangle is the only type of face you can use. Our example cube has 12 individual faces. Vertex/verticesĪ vertex is a corner, or more precisely, a point where two lines intersect.Ī face is an individual flat surface, part of a solid object. To understand what the code does, it helps if we look up the definitions in Geometry for each concept. When running the code snippet in Google Colab, we get an STL file called cube.stl with the following 3D object *# Define the 12 triangles composing the cube*Ĭube = mesh.Mesh(np.zeros(faces.shape, dtype=)) Google Colab already has Numpy installed. But, we will not be using any of those functions. Blender also has a built-in Python interpreter which gives you access to Blender’s 3D modelling functions.

Install Blenderįirst thing you should do if you don’t have any way to display STL files is to download Blender and install it on your computer.īlender is a very popular, and completely free, 3D Modelling software that is also used to create amazing 2D/3D animations and among many other things, game development. When you are ready to start, head to **Google Colab**. The first video of my series is available below:įrom a Photo to a 3D Model using Python, Numpy and NumpySTLīut I recommend that you start from scratch. Simple right? Tools that you will needīlender for visualising the 3D model(Or any software that can visualise STL files) Then I will use the pixel intensity of the resized grayscale image to determine the thickness of each point in the 3D model, thereby creating a 3D model of a photo. Then I will resize the image to the size of the 3D model I want to create.
I will load an image and convert it from colour to grayscale.
The way I plan to create a 3D model of a photo is very simple.
How I plan to create a 3D model of a Photo No embellishments and no repeats! You don’t need to know everything from the start either. I also wanted to how software development is really done. I created this series to inspire anyone who wants to do software development, that anything is possible if you just give it a go. Just to be clear, I didn’t create this series to show you an amazing solution for creating 3D models or to impress you with my rusty math skills, or even my rudimentary geometry or even my rudimentary Python Numpy programming skills. But where is the fun in that? I want to inspire You There are a few tools available to do this without any coding. I am a 3D Printing enthusiast so I set myself a challenge to use this library to create a 3D model of a photo that, when printed in translucent white is called a Lithophane. I recently recorded a four-part video series for my Youtube channel on how I attempted to create a 3D model out of a photo, using Python, Numpy, and Google Colab.įor this programming, I relied on the Numpy STL library which can create 3D models using “simple” Numpy arrays.
