Some of you may have been following the development of my little 3d texturing program, which I began in June last year and have been working on in my spare time. 3 months ago I had a diffuse painting only version, but decided to try adding support for PBR (physically based rendering) authoring with…

Just a quick one to show that I am working hard on a big update to 3D Paint. Although for myself I only currently needed diffuse painting and rendering, it become clear to me it would be more useful for others if I could integrate some multi-channel painting. So since the last release I have switch…

This past week or two I've been adding a kind of procedural texturing to my paint app. One thing I'd noticed is that just using the standard brushes gave a rather smooth, non organic blend between layers, and I thought I could do better.

The Finished Result - Alpha and Colours

My plan was to use so…

Spatial interpolation of scattered data is a vital technique used in graphics programming, games, medical, scientific applications, mining, weather forecasting etc. Some of the most widely used techniques are:

• Inverse distance weighting
  
• Natural neighbour interpolation
  
• Kriging
  

  Here I will discuss a cun…

Finally I got around to making a preview video of my little paint app. Screenshots are ok, but a video helps show how the app works a lot better. As with many projects, getting the main functionality working was quite quick, but the various redos (when I realise there is a better way of doing somet…

As regularly happens, I found myself with wrestling to shoehorn SSE code into a codebase compiled with visual c++ 6 (from circa 1998), and realised I should be checking out the more modern IDEs.

I can already hear the *gasps* from the readers. Let me explain. I am one of the users of the earlier ID…

Just a little report for anyone who is following my progress on my little 3d painting app from my previous post. I'm trying not to get too carried away spending too long working on this, but am planning to do a release earlier rather than later, even if it has lots of improvements still to be made.…

Frustrated with the clunky support for 3d painting in blender, I've been looking for alternatives. I couldn't get Mari and some others to even run on my lowly PC (intel HD graphics 3000! :lol: ). So in typical 'do everything yourself' style :rolleyes: , I decided to knock something up myself. After…

[size=2]As a first go at a journal entry, just a simple topic:
For a feature for my little 3d painting app, I wanted to be able to warp source images to make them fit better onto 3d models. Never having done image warping before I quickly came to what I presume is the basis for how most people do it…
