Last project by DirectX7

Here are some shots of my last project by DirectX7. these shots show the box which displays an animated progress bar. the animated progress bar was generated with the flash component and moved to the texture of the box. the box goes around sometimes. sprites are simple billboards that contain a texture and draw when the alpha blend is on.

These days by DirectX9 or earlier we can show so many sprites at a time by using shader and simple tricks. for example, we can render thousands of sprites by one draw primitive call by simply batching all quads and sorting them from back to front.

3D Anaglyph

I wrote this application when I was a collegian and had a midterm project about 3D stereoscopic pictures with the Anaglyph technique. Therefore you should use 3D Anaglyph glasses to look at the object at a correct 3D outside the monitor. if use Anaglyph glasses with good precision lenses, you may try to touch objects with your fingers.
You can find more information about Anaglyphic pictures here

3D on desktop

Once upon a time I thought about a beautiful 3D desktop on Windows XP. I found a way to show a 32-bit bitmap on the desktop which supported the alpha channel. ( you can find a sample here )
Now here is a test to display a 3D object in desktop.

Get Weather

This is a simple sample of layered windows in Windows XP. layered window is a new functionality that Windows 2000 introduced first. They are 32-bit graphical windows that support alpha channels for transparency and translucency to top-level windows. Implementation is so easy and the result is excellent. for more information about layered windows just click here
In this sample, I try to make a funny useful application to represent the weather in your city. I wrote the sample in the non-Unicode Pascal compiler for the Persian language and now I just do some little changes to display English fonts correctly.

Airplane

Here is a simple airplane flying over a land. the camera connection is not bad. it follows the airplane and changes up-vector when the aircraft makes a round. The sample uses a height map for collision detection. when the airplane pulls down or goes through mountains the “oops” will appear on the screen.
This one is the oldest of my works based on DirectX7 API ( Retain mode ) with an unreadable code in Delphi.

Framework DX7

Here is my first attempt to create a framework on DirectX 7 (Immediate Mode) that began around 2003/02.
The programming language was Pascal in Delphi IDE; the source code is available but dirty. because it was my first try and I was a beginner.
The simple framework has 2 parts, one is an editor called Maker and the other is a Viewer.
The Maker has 4 view ports with full-screen display capabilities. but the object creation method was in the wrong way! The sample was just a try to write down an editor, not a renderer 😀
The viewer was a simple test for lighting, fog, render states, and some features on DirectX 7. Viewers use a text file to load a scene from the Objects folder. the text file contains a list of file names and a simple position vector ( just like this: filename1.omf|x|y|z ). Each file contains vectors in binary format and all textures inside.

New site designed

Here are new designs for my site so I will post updates here. although the old site is still alive and anyone can see that from here.
The other news is that I left out developing my last engine in Pascal (Delphi2009) a couple of years ago and started a new C++ (Visual Studio) project that will achieve games in different ways. it has the old name (World Engine) but is not a DIRECT way to write a completely integrated engine. it is separated into so many steps containing tool developments, research, experiences, etc… then I will try to cover all of them on the blog.
Also, I am glad to tell you that the new Tech Museum is now ready. I will put some of my tech works from among the oldest (DirectX7) to the newest (DirectX9) and the others.
