Igor Stjepanovic18 Sep In this project I demonstrate how to write a simple 3D rendering application in a relatively small amount of code.
It helps people access, display and analyse data that has geographic content and meaning. In this article, I will demonstrate how to build a standalone 3D terrain visualisation tool from scratch using C and Managed DirectX 9. The application will allow the user to rotate the point of view using the arrow keys and to change the rendering mode to P Point, W Wire frame and S Solid.
During that project I developed a proof of concept application to demonstrate the technical feasibility of 3D visualisation using the available spot heights and aerial photography textures. The aim of this article is to share my knowledge and experience with all developers interested in GIS and.
Requirements Before we start, I would like to specify the software requirements for this project: NET framework I used v2. In order to generate any 3D terrain model, you will need some grid based data with X, Y and Z values for each grid point. A very important consideration is how the Z value is stored, as DirectX uses left-handed coordinate system while OpenGL uses right-handed coordinate system to learn about different coordinate systems, please search the Internet.
I have chosen a grid size of 79x88 simply because that is how my source data is stored, but you can change this to any arbitrary grid size. Likewise, my data uses 20m resolution which means that the real distance between two adjacent points is 20 meters. Once you read in all the points you will need to generate a "mesh".
The mesh is an array of triangles constructed from the points you loaded in the previous step. All rendering in 3D is based on triangles and arrays of triangles. Therefore, the less work your video card needs to perform the faster your application runs.
These and other similar algorithms are aimed at reducing the level of detail and number of triangles located furthest from the view point. The other way to look at this is to say that we are reducing the level of detail where it matters least, while we are preserving the highest possible level of detail where it matters most.
Finally, textures are used to provide a more realistic look of the scene. Textures use their own coordinate system, with top left representing 0,0 and bottom right representing 1,1.
Any texture point within this range 0,0 - 1,1 is referred to as a "texel". As an exercise left to the reader, further enhancements could include the SkyBox, Lighting, Shading or even Physics engine with collision detection etc.
Using your imagination, the sky is the limit! You will need to have Managed DirectX 9. However you can use a much smaller DirectX 9. First of all, we will import the necessary libraries: DirectInput; Then, we will declare our grid width and height, screen and keyboard devices, VertexBuffer and IndexBuffer, Texture, Vertex and Triangle structs and a few other variables used throughout the project: SoftwareVertexProcessing, presentParams ; device.This is how you do it: in Visual Studio, go to the Project menu, and select ‘Add reference ’.
In the list that comes up, pick ph-vs.comX and ph-vs.com3D. Be sure NOT to . May 14, · As near as I can tell, VS won't compile any code based on DX8; for me, it wouldn't even compile b code.
The best course of action would be to seek out Visual Studio (not sure if that works with DX8 code, but it should), or upgrade to a newer version of the SDK that works with (I've had no problems with December and up).
This article is intended to be a sort of step by step tutorial to start writing a program for DirectX using C#. First open Microsoft Visual Studio and create an .
If you're building for x64, then you'll want to change the "Platform" drop list to "x64" and add the DirectX SDK/Lib/x64 directory instead. If you're not sure what you want, then . Apr 19, · Describes how to write ANSI C programs by using Visual C++.NET or Visual C++ C program by using Visual C++ application wizards in the Visual ph-vs.com or Visual Studio IDE.
Note In Visual Studio , click Visual C++ under Project Types. Under Templates.
I also assume you have your own copy of Visual Studio. (Note: I use the Visual C++ Express Edition from Microsoft; if you are using Visual Studio , there might be minor variations.) Furthermore, I assume you have the DirectX SDK installed in your computer.
