Sometimes I have this coding itch, that doesn’t let me do anything until I’m done with developing an idea. I actually thought that I wouldn’t bother implementing the mockups I did earlier today. But in my way home I realized the implementation was actually trivial. With no further delays, the next screen is not a mockup, but a real screenshot from a patched Blender:

You are right Momo, groovy!

The complete patch is in the Blender Tracker, but the essence of the code is:

//given xco, yco and percentage
int barsize = 60;
// draw in black first
glColor3ub(0, 0, 0);
glBegin(GL_QUADS);
    glVertex2f(xco + 1 + barsize, yco + 10);
    glVertex2f(xco + (1 - percentage) * barsize - 1, yco + 10);
    glVertex2f(xco + 1 + (1 - percentage) * barsize - 1, yco - 1);
    glVertex2f(xco + barsize, yco - 1);
glEnd();

Any comments and feedbacks are still appreciated.
Time to sleep 😉

I’m reading a very interesting book on data visualization for science. (Visual Strategies by Felice C. Frankel & Angela H. Depace). The book was highlighted in last month’s Nature magazine, and is indeed highly recommended for scientists or science communicators like myself ;).

Today Mitchell asked me to look at a patch he was reviewing and adding his own changes. The patch by Angus Hollands re-organize the interface for debugging. Well, I couldn’t help giving a try at representing the numbers in a more direct way. I don’t how hard would be to implement those ideas, here are mockups only for the sake of my creative exercise. Thoughts?

Original proposal by Angus Hollands (agoose77) with changes from Mitchell Stokes (Moguri)

Why not visualize the percentage?

A more radical approach

The talk starts at 16:00 Amsterdam time (14/October/2012)

In less than half an hour I’m presenting a talk at the Blender Conference 10th years anniversary edition. The presentation will be streamed online, and if you want to follow the presentation with the slides I will use, you can download it here.
