Perspective : 3D relative transforms for WPF

odewit — Sun, 21 Feb 2010 16:25:00 GMT

Presentation of the RelativeTransformer class, from the Perspective library, which can apply successively moving, sizing and rotation operations on a Visual3D, by memorizing its position and its transformation matrix.

Perspective FX 1.0 : easy image editing for WPF and Silverlight

odewit — Sat, 30 Jan 2010 22:19:00 GMT

Perspective FX 1.0 released : see how to adjust contrast, brightness and saturation of an image, and how to build custom effects by simply assembling filters, without HLSL skills...

Here is an example of saturation adjustment done with the Saturator filter :

Silverlight 3.0 from scratch

odewit — Sat, 07 Nov 2009 20:09:00 GMT

For pedagogical reasons, or to build a code generator (like Perspective Fx does), it may be useful to compile Silverlight code on the command-line. Last year, I wrote an article for Silverlight 2.0 about this subject. I have adapted it today to Silverlight 3.0.

The main differences are at the paths :

libraries path (/lib compiler option, .rsp file),
MsBuild Microsoft.Silverlight.CSharp.targets task path (.proj file).

Perspective FX : a ShaderEffect generator for WPF and Silverlight

odewit — Tue, 30 Jun 2009 20:17:00 GMT

Usually, writing custom graphical effects classes for WPF or Silverlight requires some HLSL programming skills. For a .NET programmer, learning this language may be sometimes long and tricky. The Perspective FX framework aims to help you to build custom effects classes without HLSL coding. You build an effect by combining graphical filters in a XAML file. The HLSL code and the .NET wrapper are automatically generated and compiled into an assembly that you can use in a WPF or Silverlight application. Tutorial

Many thanks to Sebastien Reynier, MSP, for his collaboration :-)

A new book (in french) about Silverlight 3... mine :-)

odewit — Tue, 09 Jun 2009 21:51:00 GMT

My book about Silverlight was published yesterday :-)

It's aimed at developers who want to make rich Internet applications: .NET Web developers or Web .NET developers ! The fundamentals are presented in Silverlight 2 and 3, and a chapter is dedicated to the specific features of the version 3. The example code is divided into several applications that use the Perspective for Silverlight open-source library.

Enjoy !

Perspective 1.0 : new pedagogical resources for Silverlight 2 & 3

odewit — Sat, 30 May 2009 10:49:00 GMT

Version 1.0 of the Perspective library for Silverlight 2 and 3 has just been published. It contains custom drawing classes, custom controls and custom panels, which can be used as it or which may serve as inspiration source. It also includes classes that facilitate databinding, internationalization, assembliy loading and navigation among the pages of a Silverlight 2 or 3 application.

Main changes :

Knob Silverlight custom control, and databinding between elements

Polygons and honeycombs - PolygonElement custom drawing class, BeePanel and BeeGrid custom panels

MayaEase, a custom easing for Silverlight 3 animations

Perspective for Silverlight

odewit — Tue, 27 Jan 2009 21:45:00 GMT

In the same experimental and pedagogical spirit as Perspective for WPF, here is Perspective for Silverlight :

dynamic on-demand Silverlight package, assembly and object loading,
simple but effective page navigation framework,
localization system based on resx string libraries, using the standard .NET satellite assembly mechanism.

Silverlight from scratch

For many reasons, including pedagogical ones, it may be useful to compile Silverlight 2 code on the command-line, without using Visual Studio. Here is my article on this subject.

Hi,

I'm currently at the PDC :) and started to blog here in french.

Converting RAW files into JPEG with WPF

odewit — Sun, 07 Sep 2008 16:43:00 GMT

This new article shows how I built the ImageToJpeg tool to convert into JPEG the RAW files of my Nikon camera.

RAW files contain raw data issued by the sensor. They constitute the original pictures, and have the same value as the traditional photo negatives. With this tool, I convert them to JPEG files specifying a compression ratio depending on use sought.

A tool for building circle arcs with WPF

odewit — Thu, 03 Jul 2008 19:52:00 GMT

The ArcSegment class is not easy to grasp. Despite the illustrations of the documentation, it is often necessary to grope to get the desired result.

In WpfDemo, the example application of my book about WPF (in french), I developed a WPF page that directly shows the effect of the various properties of this class.

ArcDemo.xaml (.NET 3.5 SP1 XBAP)

~~Note : this module does not work in .NET 3.5 SP1 beta, which introduces a regression bug.~~ Fixed for final .NET 3.5 SP1 release on September the 7th, 2008.

Perspective

Hello,

I'm Olivier Dewit, a french technical book author. I'm coming from msmvps.com and I will now blog here about WPF.

I'm writing a book about WPF, in French. My contribution to the community is Perspective, an experimental and pedagogical .NET class library which contains :

High-level 3D shapes : Box3D, Bar3D, Spherical3D, Conical3D, PieSlice3D...
3D interactive and skinnable controls : Button3D, Knob3D, Fader3D...
Workshop3D : a ready to use viewport for 3D models, with light, moveable camera and camera control panel.
2D controls : Knob, Fader, Joystick
Other stuff to build skinnable and international applications (desktop and XBAPs)
...

I've just published the 0.9 version. You can run an online demo here (this is a .NET 3.5 XBAP). Here is an article about 3D programming with Perspective.

Enjoy :-)
