• CrystalDeveloper Perspective projection

  Hi, I'm working on a 3D engine, but I'm stuck on perspective projection. The documentation is a bit confusing. I've got some wireframe objects moving around so far, but I need to add the perspective distortion, as well as move the points so they're relative to the screen's centre, rather than its top/left. I know how to do this with calculations: X' = (X*D) / (Z + D) Y' = (Y*D) / (Z + D) Then X' = X' + (vWidth/2). and Y' = Y' + (vH ...Show All

• Nightmare_BE DrawIndexedPrimitives

  I am going not so nicely nuts here trying to get an Indexed primitive draw working. I have code that works and happily draws a rectangular plane using DrawPrimitives against a TriangleStrip, this works great but I wanted to make a more complicated object so I thought lets make this work with indicies. I added a short array with the indicies in and set it all up to use the indicies based on my verticies and a Triangle List. Thing is it doesn ...Show All

• Inuya5ha Problems setting parameters in HLSL effect

  Hi I'm trying to get a basic effect running in my engine, but I am having difficulties getting the parameters from my code into the effect. They seem to be sticking at the initial value. For instance I have added time to the glow EffectEdit sample and added a sin(time) term to make the glow pulse. It works fine in EffectEdit, but in my engine, the time sticks at the initial value of zero. I have verified this in the debugger, I am setting th ...Show All

  We started using the Dec 2005 Sdk, and then upgraded to the Feb 2006 Sdk. We installed the Feb06 Sdk only after uninstalling the Dec05 Sdk. On some machines running XP the system seems to still be using the older Dec05 Sdk dlls, even though the Microsoft DirectX SDK (December 2005) folder has been removed by the uninstall. The problem is when we intialize XACT with our xgs file, we get the invalid data error(All data building, compiling and li ...Show All
