Inspired by the latest Intel GPA I’ve developped a little control that can display a value over time.
Very usefull to debug or to find time consuming function at runtime
Another Brush test with our mascot Scleacky.

For a project I need to simulate simple shadow and glowing effect without to have to render a shape into a BackBuffer and to compute a Blur.
So I decide to code a LinearGradient Stroke. This Stroke simply toke the distance to the shape and then output a nice gradient.
Whith correct color and blending I got a sheap blur/shadow effect for my shapes.
Little video of the Prod Presenter i’ve coded at the VIP2011.
The VIP2011 is a DemoParty organised by the demo group PoPsY TeAm near Lyon.
The Prod Presenter is an application who get the property of each productions from the compo server and generate the animated screen automatically in real time.
This tool is really time saving because we don’t need anymore to edit a PSD for each compos. it was a very painfull operation after 2 days without sleeping.
I’ve developped the application at the party place, it’ was a lot of fun ;)
and The Graphic design was made by Taggy

A preview of a real time 3D music visualizer developped by Bleank ( not already released ) used to entertain the audience :)
Gamma Correction
On twitter I saw this tweet from John Carmack
And it’s remember me an entry on the blog of John Hable about Gamma Correction.
I’m currently developing User interface rendering with DirectX and shaders then I must take car of correct Anti aliasing computation for typos or little vector shapes.
But I never reach the contrast of the font system rendering. I know there’s some hinting and clear type on it but I was not satisfied by my results.
So I decide to read carefully this excellent article about Gamma Correction and made some test.
The result was what I excepted at the beginning. The font rendering is now contrasted and even really little characters are now lisible and clean.
Here come the result :
Before whitout Anti-aliasing Gamma Correction
After with Gamma Correction
Thanks to the two John I will take care of the correct Gamma Correction everywhere in my framework for event better rendering ;)
Drawing test in a Virtual Texture ( video version of this post ).
You can admire my special coder art drawing skill….
I have also implemented a Undo/Redo mechanism and a simple Brush who is drived by the velocity and the pressure of a Wacom stylet.
The fps is clamped to 30 because of the video capture but the application run in full 60 fps all the time.
Due to virtual texturing caching and full hardware rendering it’s possible to cover very large part of the picture without sacrifying the fluidity of the application ( unlike a lot of drawing software who suffer server lag in that case ) and then to produce some kind of nice Calligraphy.
Calligraphic Brush Test.
The brush take into account the speed and the pressure of the pen to achieve this kind of result.
I worked on a Undo/Redo system who doesn’t hurt the drawing flow today and Bonnie has made this beautifull “Evil Poulet” to thanks me.
Enjoy ;)
8Kx8K pixels ( 61 Mega pixels ) Image drawing at 60fps
Due to vector rendering the artist ( here bonnie ) conserve high detail if he want to print it :)
