What is Picture to People ?

"Picture to People" (P2P) is a huge Computer Graphics project. It was started to create new softwares able to make 2D drawing, 3D rendering, vexel drawing, text effects, photo effects, image filtering and other complex Computer Graphics operations. It has been made from scratch, including its low level Computer Graphics libraries like Maccala. Nowadays, most final features produced for this project are released as free online tools available from its official website. This blog talks about Computer Graphics, mainly concerning Picture to People development.

3D Text: rendering with global illumination

It has been almost 20 years I'm involved with Computer Graphics studies, researches and developments. Most of this time I spent with Digital Image Processing and artistic filters, effects and transformations. During this time, I have dealt with 3D CG several times, but my main focus always was on 2D world.

Since two years and a half ago, I decided to make serious 3D tools for Picture to People project. I have been studying and researching about 3D during this time, handling many different math models, algorithms and techniques.

A ray tracer to create 3D realistic texts is an old dream that is ongoing. I will need a good piece of time to finish it yet. So, in this meantime, I decided to make other 3D text generator using other paradigm. I would implement it anyway sooner or later.

It's already under development a text renderer based on global illumination algorithms. I'm trying to find a good point between impressive results and reasonable performance.

One interesting thing about this kind of software is: it can generate natively very realistic soft shadows, what gives a very convincing 3D look to the models. Direct illumination methods (like ray tracing) are not good to create this kind of shadow that is very common in nature. Each paradigm has its strengths and weaknesses.

Well, let me show what I'm talking about. Below you see two 3D texts created with a global illumination renderer.

By the way, I have an important thing to celebrate today: it's my post number 200! Most blogs are abandoned before getting one year old and I'm still here. I started this blog in October 2007 and a lot of Computer Graphics subjects were discussed here since that time. This blog tells a lot about Picture to People evolution in recent years.
