• Sternman DirectX batch sizes and Impostors

  Hi, I am working on an implementation of the Hierarchical Image Cache by Shade et.al. In short, it uses a spatial hierarchy of dynamically updated impostors to avoid having to re-render the base objects for as long as possible: if possible, an impostor is updated by rendering its direct children (which are also impostors, but of a smaller subset of the scene) instead of the full geometry. I have already written a working implementation in Open ...Show All

• Sunil Sinha how to save a progressive mesh to a .x file?

  When using ID3DXPMesh to simplify the model, I want to export the data of a progressive mesh to a 3D file. I know D3DXSaveMeshToX can save ID3DXMesh to a .X file, but how to save a progressive mesh to a file Any suggestions will be appreciated. Thanks a lot:) Lily You should use the Optimize method from ID3DXPMesh. This method creates an ID3DXMesh object that you can save ...Show All

  I'm using the following code to get a non-square texture from a bitmap: D3D . TextureLoader . FromStream ( graphics , loMS , bmp . Width , bmp . Height , 0 , D3D . Usage . None , D3D . Format . A8R8G8B8 , D3D . Pool . Managed , D3D . Filter . Linear , D3D . Filter . Linear , 0 ); (Where "bmp" is a Bitmap in memory, and "loMS" is a MemoryStream connected to bmp). This works fine on my PC, but if I run it on a lapto ...Show All

• Felix Planjer Dynamic Vertex Buffers

  Hi, I am creating vertex buffers up to 60,000 vertices. Vertices contain up to100 bytes of data. Vertex Buffers are dynamic and need to be set each frame. I am currently using VertexBuffer.SetData(...) to do this. I have around 10 such buffers per frame giving a total of 600,000 vertices. There is however a maximum of 60,000 of these 600,000 that are meaningful (need to be rendered) each frame. These are set as the first x vertices in each bu ...Show All

• Rasim_Yilmaz VertexBuffers: Lock/Unlock and same memory address....

  If i create only one static vertex buffer in my program and i do: Lock/Unlock....Lock/Unlock....Lock/Unlock....etc - all this calls return me same start memory address for vertex buffer data if this buffer not been recreated or not P.S. sorry for my english pls :) It might or it might not. But do NOT assume you will always get the same address. Also, NEVER write to the address without doing a Lock first, and ...Show All

• QuBit0 Console Flicker

  I'm creating a small text based game in console mode.  I want to spice it up a little by having a few animations like animated text and boxes that animate their opening and closing.  To do this I have created a buffer (an array if CHAR_INFOs) and write everything to that array and once per update (the screen updates at 30 times per second) I use WriteConsoleOutput to display the buffer.  This works great and the animations look re ...Show All

• Jianpeng Is it reasonable to build cos/sin/acos/asin func textures? (HLSL)

  I'm just wondering if it is reasonable to build function textures for the cos/sin/acos/asin in a HLSL shader. Or is it quicker to use the respective HLSL functions Nico Thanks! I actually removed the acos completely using an approximation for the computation where the acos was involved. Before that I simply replaced the acos by a 2d texture lookup in an abrbitrary texture to compare the performance. As your ...Show All

• DennisR Game Networking...

  I've just been reading "C# Network Programming" by Richard Blum in order to get up to speed with networking (non-http, most of my C# experience is in ASP.NET). Now, he shows many examples of how to network in the book, and I've learnt some great things, but after reading Tom Miller's book, it's left me wondering how much is going on in the background of .NET and which approach is better for an MMO style game. In Richard's book he shows fi ...Show All

• MikeAlister Animating a leg

  hi all, I'm trying to create a simple animation of a leg. The leg would be made out of two parts and each part would be a mesh (could be just Mesh.Cylinder). I know how this should work in principle but when I have to calculate the matrices all goes wrong... Here's my idea: Given the angles of rotation for both parts rotate and position the upper part (which will maybe be someday connected to a torso) then rotate the lower part and c ...Show All

• mariascandella Can Windows Workflow Foundation help making games?

  I was just wondering after reading some docs about it: will we be able to use it to develop games anyway I mean, define the workflows that happen in a game Thanks in advance, Well, it would still be very good to have a tool such as this to game development. Anyway, thanks for your reply. Is is highly unlikely it is suitable for gaming purposes.  It is primarily intended for business/process workflow management. ...Show All
