Making a custom mesh in C# managed DirectX

I need to make a DirectX 3D mesh at run time using Managed DirectX from C#. I have not been able to locate any information on how to do this. No, I can't use a 3D modeler program to make my objects. They must be precisely sized and shaped, and I don't have ANY of the size or shape information until runtime. No, I can't build up the m...

Mesh networks resources

Anyone got any pointers to good resources concerning mesh networks? Maybe I'm not even using the correct terminology. I need to write an app that has multiple agents on various machines, and each agent must have knowledge of and be able to communicate with the others. A type of P2P application perhaps? I'm really looking for some archit...

Windows Live Mesh Limitations...

I am considering using Live Mesh to replace rdist, syncback(ftp tool) and a few other tools I use to sync files between systems. So I thought of asking these questions before I decide to replace what is already working! Does Live Mesh has any file size and number of folder limit for syncing between machines (I am not talking about the ...

Rendering large numbers of meshes (objects)

I have a project where I am looking to render a large number of meshes over a 16 square mile landscape. While the meshes are not all unique, there are a lot of them (Probably only 1000 meshes but several million usages of them) I was wondering if there were any papers or (good) resources covering the topic. I have found loads of papers ...

A Java Mesh Library ?

I'm currently looking for a Java Mesh Library. If my understanding is correct, this would be something similar to OpenMesh. All I've found at moment is JMesh 'A Polygonal Mesh Library in Java' (http://jmesh.origo.ethz.ch/) which is still in development. Context : turning a very large stl file into a Mesh structure (probably winged- or...

Rendering a 3D mesh object

I have a problem about rendering a 3D mesh object. I prepared the 3D mesh object in C# and rendered it. Unfortunately, the edges that must be sharp are camber. Could one explain me what the reason is. I am using visual studio 2008 - C# Express Edition. The 3D closed mesh object has appr. 66.000 vertexes. At the same time, it has not ...

How to map a point onto a warped grid

Say you have a collection of points with coordinates on a Cartesian coordinate system. You want to plot another point, and you know its coordinates in the same Cartesian coordinate system. However, the plot you're drawing on is distorted from the original. Imagine taking the original plane, printing it on a rubber sheet, and stretch...

Wireless Mesh Network based on cheap consumer routers

I wanted to know if any such system already exists for the average open source user. With all of the net neutrality arguments around and with the cost of broadband likely to go up in the future. It seems like a good idea for a open source protocol which allows standard consumer routers to operate together and form a mesh network with o...

Mesh Generation in MATLAB

Is there any subroutine, in MATLAB, that takes in a list of points, and return me a good mesh that I can use to show to my colleagues, such as this? Actually, all I need is just a simple 2D mesh generator that takes in a series of X, Y coordinates (that defines the boundary of the area), and give me back a list of elements that can me...

Creating spherical meshes with Direct x?

How do you go about creating a sphere with meshes in Direct-x? I'm using C++ and the program will be run on windows, only. Everything is currently rendered through an IDiRECT3DDEVICE9 object. ...

Does Live Mesh exclude .aspx/.ascx files?

I'm tired of zipping up my ASP.net MVC project all the time, so I tried to connect the entire project folder to Live Mesh, so I could work on it both at home and at the office. It seemed to work, but it turns out all the views are excluded and replaced with .wlx counterparts. Is this a known limitation of Mesh? Does anyone know of a wor...

Direct3D Mesh with combination of lines and triangles

I need to create a Direct3D mesh consisting of some vertices (generated at run-time) which I need rendered as a combination of LineList and TriangleList. i.e. some vertices are rendered as a LineList and some of them as a TriangleList. How can I create this Direct3D mesh? ...

Blending animations in DirectX - is this technically possible?

I have an animated mesh in the .x format I've loaded with D3DXLoadMeshHierarchyFromX and have an animation controller for it. The mesh has two animations, one for walking and one for throwing where the walk animation. Is it at all possible to blend the two animations in such a way that both animations can run together with the walk taki...
