Lawnjelly's Journal > Procedural Texturing in 3D Paint

Posted 06 October 2016

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

Lawnjelly's Journal > Fast Discrete Natural Neighbour Interpolation

Posted 30 September 2016

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
 Here I will discuss a cunning optimization of discrete natural neighbour...

Lawnjelly's Journal > 3D Paint Preview Video

Posted 05 September 2016

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 something) and the polishing take 90% of the time. I will do a...

Lawnjelly's Journal > C++ IDEs - a rant

Posted 22 August 2016

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 IDEs who has been most unimpressed by the later offerin...

Lawnjelly's Journal > 3D Paint App Progress

Posted 30 June 2016

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. I've already got most of the features I was aiming for wo...
