Some months ago, I interviewed for a job as a junior graphics programmer for various game companies, in order to break into the industry. Since computer graphics is a very niche field, there is not very much information out there on what qu

yeah, radial basis functions are awesome :)

global refinement and unrefinement steps are unnecessary, yes. It just makes the implementation of the demo so much easier. It is possible to only refine the patch, and then fuse the patch with the original mesh, and then global refinement

Yeah, I think it's heavily inspired by that yes. Many techniques in geometry processing take heavy inspiration by image processing techniques.

I also appreciate the provided references.

I agree with you mostly. I just think that this is an interesting usage of variational calculus, which is not that well understood by other programmers, so I wanted to write this article about this, in order to introduce other programmers t

you can see more examples in the linked repo: https://github.com/Erkaman/poisson_blend

yes, the mask is also pretty important. otherwise, you get lots of stuff from the background of your source image in your blended image, which often looks pretty bad.

since the technique is so simple, it's probably not hard at all to include into GIMP. Wouldn't surprise me if someone had already implemented a plugin for it.

In this artice, I describe a technique that can be used to seamlessly copy-and-paste one image into another. I also provide source code( https://github.com/Erkaman/poisson_blend ), that demonstrates the concepts in the a

Basically because it takes a lot of calculation and time to add them, so I didn't add the feature yet. I am working on making the calculation faster.

Hi, this is a demo that me and my friend have worked on for some weeks. Note that it takes a while to load the demo In case the demo doesn't run, I have prepared a video of it here( https://www.youtube.com/watch?v=1bykYC

OP here. This is a small code example of how to use Vulkan for compute operations. Only ~400LOC. It's pretty short, and has plenty of comments, so it should be useful for people learning Vulkan, I hope.

Hello, I'm the writer of this demo. Because this is WebGL, this demo may or may not run, so here( https://github.com/Erkaman/webgl-rsm ) you can see an image of what it should look like. This is an implementation o
