Press ENTER and you should see the frame of a camera appear.Īt this point, we can still move our view around and all we need to do is click on the camera icon on the top right of our scene to go back to this camera view: Then, use the spacebar and type “Align Camera to view”.Pan and move your view in the viewport until you have a good view of the object (the controls for this differ, but on my MacBook I use the trackpad with two fingers to pan, CMD + two fingers to zoom and SHIFT + two fingers to move the viewpoint).Go to File->Import->.obj and select your output.obj.Click on the cube on the middle of scene and then on the letter X to delete it, we won’t be using it.This is something Oded Stein taught me when I started using Blender and it will completely change how you use the software for the better. This will give you a very useful way of navigating the UI, instead of looking for each button you can just press spacebar and search for whatever is you’re looking for. ![]() You’ll see something like thisīefore you do anything, go to Edit->Preferences, and on the Keymap section, pick Spacebar Action: Search. Open Blender (you can download it from here). Let’s pretend you wrote a fancy new method in C++ or Matlab or Python that outputs a mesh called output.obj, and you want to render it to put it in a paper figure (if you want to make an animation for your paper video, please see my other guide). Another goal of this guide is to share my pipeline with people from other labs so that they (you) can hopefully learn something but also teach me something I am currently doing wrong or less efficiently (please email me!).Īnyway, here we go. Mitigating that frustration is the goal of this guide.Īlso, one only needs to look through SIGGRAPH publications to see that all labs seem to have their own really polished “paper-quality rendering” pipeline, but unfortunately in my experience these mostly stay at the “tricks of the trade” level and aren’t shared very widely (not out of malice, there just aren’t many incentives for it). For this use case, there is way less documentation online (my labmate Derek’s Blender scripting toolbox is a great exception), and in my experience this can lead to a lot of frustration especially when nearing deadlines, when one does not have the time or energy to learn a whole new aspect of the software just for a minor change in a paper figure. These are really interesting topics, but they can be overwhelming if you are an academic and all you want is to render your object beautifully for a SIGGRAPH paper figure. Therefore they go into depth on how to model a shape, how to pick the best lighting, how to design a material, create textures, etc. There are a lot of great Blender tutorials online (e.g., the classic donut tutorial by Blender Guru), and they are usually aimed at artists or animators who want to generate full scenes from scratch for short films.
