Blender 2D To 3D: Complete Guide To Turning Flat Art Into 3D Models

What is Blender, and how does it handle 2D to 3D conversion

You can use Blender, a free and open-source 3D program, to generate models, animations, renderings, VFX, and games. Its tools are flexible enough for artists to bring their ideas to life in 3D. One of the most incredible things about Blender is the Grease Pencil. It enables artists to create three-dimensional drawings and transform simple sketches into detailed models. When you switch from 2D to 3D in Blender, you typically begin by importing 2D images or vectors, applying modifiers and extrusion techniques, and then refining the results until they are fully manipulable 3D assets. Artists may utilize Blender's 2D and 3D tools to turn simple drawings into complex 3D objects that move and can be used in games, animations, or visualizations.

Step-by-step guide to convert 2D into 3D in Blender

To turn Blender 2D to 3D images, the first thing you need to do is use Inkscape to turn the image you want into an SVG file. SVGs retain vector paths that can be used to create 3D objects later. Once the SVG is finished, it is brought into Blender, where it is extruded and turned into a full 3D Mesh. This completes the process of converting 2D to 3D in Blender. The procedures are listed below.

Stage 1: Steps to convert an image into SVG using Inkscape

The process begins by turning a flat raster image into a scalable SVG graphic that Blender can read. The detailed steps for carrying out this conversion are outlined below.

STEP 1
1. Open Inkscape and import your image

To open Inkscape, click on the black diamond symbol. Then, go to File → Import to bring in your artwork. Select a clean, high-contrast JPEG, PNG, or GIF (logos, line art, or typography work best). Place it on the canvas and position it where you want to trace it for smoother results.

STEP 2
1. Trace the image into an SVG

Select the picture, then click on 'Path' and then 'Trace Bitmap'. To get a live preview, select a scan mode (Edge Cutoff, Edge Detection, Colors, Brightness Steps, etc.), adjust the thresholds or color counts until the preview appears satisfactory, and uncheck the 'Smooth' box for sharper paths that work better in 3D. To remove speckles, smooth out corners, or enhance routes, navigate to the 'Options' tab and adjust options like: Suppress Speckles, Smooth Corners, and Optimize Paths.

STEP 3
1. Edit and refine the SVG shape

To make the traced vector, click OK. Then, move the new form away from the original raster and erase the raster picture. The 'Edit paths by node' tool can be used to remove stray nodes, adjust curve sharpness, and combine or split shapes to ensure your vector is clean and ready for conversion into a mesh.

STEP 4
1. Save as SVG

When the vector looks right, click File → Save As, give the file a name, and save it as an SVG file (simple SVG is OK). This SVG file preserves the vector pathways you just created and is now ready to be imported into Blender, where you'll convert it into a 3D mesh.

Stage 2: Steps to convert SVG to a 3D Mesh in Blender 3D

Once the SVG file is ready, you can bring it into Blender and transform it into a fully editable 3D mesh. The exact steps for performing this conversion are outlined below.

STEP 1
1. Open Blender and set up the workspace

To start, open Blender 3D by clicking on the orange, white, and blue symbol with orange lines at the top of your screen. When you first launch Blender, it displays a simple scene featuring a camera, a light, and a cube. To remove the cube, click on it and then press the Delete key. This will clear your workspace. To access the Top View, press '7'on the number pad or select View > Viewpoint > Top.

STEP 2
1. Import and adjust the SVG

To get your design into Blender, click File > Import > Scalable Vector Graphic (.svg) and choose the SVG file you made in Inkscape. After you import the SVG file, use the mouse scroll wheel to zoom in till you can see it properly. To choose it, click and drag a box around it. Then, press G and drag the mouse to change its location. To make the SVG fit perfectly in your workspace, use the S key to resize it to the desired size.

STEP 3
1. Convert SVG to mesh and extrude

Select the SVG, then go to the Object menu and choose Convert To > Mesh from Curve/Meta/Surf/Text. This step turns the flat SVG into a mesh that can be changed. To go to Edit Mode, click on the Object mode in the upper-left corner of the 3D viewport. To select the whole mesh, press A. To observe the flat shape from the side, switch to a Side View by pressing the number pad keys, like 1 or 3. Last, hit E to extrude the faces and then drag up with your mouse to give your mesh its initial 3D shape. This process effectively converts your 2D SVG into a solid 3D model.

STEP 4
1. Apply materials and save your work

Press Tab to return to Object Mode after the extrusion is complete. To make your 3D item look real, click on the 'Material Properties' tab (the red sphere symbol on the right toolbar). You can change the base color, metallic for the level of shine, specular for the brightness of the light, and roughness for the smoothness or matte finish. When you're satisfied with your design, go to File > Save As, enter a name for the file, and save it as a Blender file.
