I continue experimenting brush rendering for BlackInk
Here I render Ellipse Stroke instead of Filled Ellipse on the Brush path, the result is better than I though.
I also test the result with a Simple rectangle and the result is more like a real Calligraphic pen.
NB : I will do a presentation of BlackInk at the VIP2012. So don’t miss the event ;)) and see you there.
Camera capture of the first launch of BlackInk a new Drawing software developped by Bleank.
The main purpose here is to show the SplashScreen featuring little fluid effect on top of the user desktop with transparency.
How I render DirectX on your desktop ?
Quiet simple I used this excellent article on how to draw directly on the desktop with a DirectX 9 bacbuffer. It’s pretty nice. The only problem is that it doesn’t work if you used DirectX10/11 becasue the WDM doesn’t handle correctly the backbuffer with these API. The good news is it’s only on Vista because Windows 7 ( and futur Windows 8 ) use at least DirectX10 and can now handle the alpha correctly.
It’s important because without it your rendering will be overburned and will look wrong.
Little drawing I did in several minutes using a Shot from the Cleack Project.
The native resolution is 6300x3400
We will release soon video of how to do pictures like this with BlackInk a software that I develop for Bleank

Here’s 3 pictures done with BlackInk in few seconds.
Bleank will soon open a closed Beta so if you’re an artist and you’re interested in trying a new drawing sofwtare you can contact me.
BlackInk Teaser video
Claudine Ricart has tested an alpha version of BlackInk an application developed by Bleank.
This drawing application is highly responsiveness and can precisely handle pressure and speed movement from the artist.
This little teaser show someone who don’t have the habit to use painting software like Photoshop or painter and sketch in several minutes with great pleasure.
Technically all the rendering is done by the GPU in virtual texture of any size ( limited in 32bit by 10Kx10K pixels ).
We also put a lot of effort in the user interface but more infos and screenshots / videos will emerge soon.
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.
Painted by me in 2 minutes with our custom drawing software in development.
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
Bonus

A preview of a real time 3D music visualizer developped by Bleank ( not already released ) used to entertain the audience :)
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 :)
2D Virtual Texture Test
This video show a 38Mega Pixel image ( 8000x5000 pixels ) with trilinear filtering with a maximum of reactivity.
Based on this kind of paper :
