![]() Why we still have edges even if we have set voxel_edge to zero? This is due to the float-point precision. I tuned the direction and color of the light to add a touch of the autumn air. ![]() set_background_color ( ( 0.5, 0.5, 0.4 ) ) # Color of the sky Scene = Scene ( voxel_edges = 0, exposure = 2 ) # Create a scene, specifying the voxel edge and exposure. Our renderer does not support volumetric fog, but we can simulate autumn sunset with a 45° directional light source ( set_directional_light()) and a yellowish light color ( set_background_color()) instead. The autumn theme has three key elements: trees, forest floor covered by fallen leaves, and volumetric fog. Using voxels to create a forest in the autumn air As a workaround, use Taichi Lang v1.0.0 instead: The next Taichi Lang release will ship the fix. It has been reported at that Taichi Lang v1.0.1 has some compatibility issues with the Vulkan backend in some environments. If you are also a voxel art lover, you are very welcome to join! Let's compare 'voxels' and motivate each other! For more information about how to participate, see the Voxel Challenge README at Just so you know, Taichi Voxel Challenge 2022 is getting heated. If you wish to create your own voxel world, start by using our template repo If you wish to try out the autumn theme for yourself and view the complete source code (91 lines of Python code in total), you can clone my repo at. If you are using an ultimate GPU like RTX 3090, it will definitely run much more smoothly. It runs fine on my Macbook (20 FPS) except for some noises, and the noises subside quickly after you pause. The source code is in Python and compatible with almost all platforms. When finishing reading this post, you will be able to create your own 3D voxel world. Program in Python and indulge in the 3D voxel world If you are unfamiliar with Taichi Lang, read this. Taichi Lang is a parallel programming language embedded in Python, allowing your program to be accelerated by your GPU. Note: So long as you have basic Python programming knowledge, you will be able to follow the rest of this post. It must be very interesting to reproduce a tranquil autumn theme with voxels and use ray tracing to render it! Then I found from online the following picture: a quiet forest in the autumn air. Forest is a common theme in many great voxel artworks. The themeįinding a beautiful theme is half success. I'm not a mighty Minecraft developer, but, thankfully, I can program to batch process the voxels. Considering the huge amount of work involved in developing the UI, if we could only edit voxels one by one, it would take ages to get the intended results! ![]() When finishing off the program, we became aware of something more serious: It is much easier for an experienced graphics developer to code a path tracing renderer than to come up with a scene setting for a beautiful image. With Taichi Lang, one can easily create such a renderer ( ) in around 300 lines of code. As far as I know, apart from Taichi Lang, there's no such tooling in the Python ecosystem for generating GPU path tracing voxel renders. Taichi Lang is embedded in Python and it runs on any operating system and can easily interact with Python. Soon, before we were back home, we had our prototype: Since we happened to mention Minecraft and MagicaVoxel, we decided to do a Hackathon, where we use Taichi Lang to create a GPU path tracing voxel renderer. Graphics card: NVIDIA GeForce RTX 3070 Driver: 465.27īlender version: 3.0.On a Sunday afternoon about a couple of months ago, when Ye and I were on our way back from a long week of travel, we decided to do something to relax on the train ( to kill time). I just don’t know for sure and hence I am sharing the bug. The image texture I do have that produces the bug is however not mine and I do not believe I can share it publicly, so I’ll share it with you and in a private message here on devtalk.ĭisclaimer: This may not be a bug at all, but instead just me compiling my build of the Cycles-X branch incorrectly. From my understanding the bug requires the use of a image texture to cause it, and I’ve tried a handful of images yet none of them seem to produce the bug. I’m not 100% sure of the cause, and I’ve had a hard time re-creating the bug from scratch. I was looking at another project and came across some issues. ![]()
