Good day, commanders!

[smile] Good day to you too!

I have created a speedmeter for the car in CustomVertex.TransformedTextured.Format (XYZRHW).

Just the usage of TransformedTextured is enough to make your task impossible. By providing transformed vertices you are explicitly telling the Direct3D pipeline that you dont want any matrix transformations or vertex shaders applied to it - and that it should pass it straight through to the rasterizer.

Three options:

1. Modify your vertex buffer. You say you dont want to do this, but it is the simplest method (from a coding point of view)

2. Switch to proper 3D geometry and use an orthogonal projection matrix. It's slightly more involved and harder to get pixel-level accuracy, but it enables the transformation units in the pipeline.

3. Use vertex shaders and pass in a simple float2 (x,y) coordinate and let the VS handle the custom transformation for you.

Hello again Maxim,

There's also option 4, using Sprite objects to render the speedometer. In the source for my 4e4 game you'll find an example of how this can be implemented. It's a bit messy, but you can find the implementation in Common\Compas.cs.

Hope this helps :)
