AWD + custom gauges thought

[joevenzon]

Wouldn't it be more sensible to update the quad's texture with the needles and any digital read-outs drawn on? That way the needle is positioned automatically.

Possibly by drawing the guages to separate SDL surfaces and updating the texture from them?

Doing rotation like that in software (if that's what you're suggesting) is quite slow, and uploading a new texture each frame is also relatively slow. Rotating a quad in hardware is super fast. Besides, it doesn't gain you anything to draw to a separate surface and then updating the texture -- you still have the problem of defining where the needle graphic needs to go and how far to rotate it, etc. The idea is that each car would/could have a separate graphic for the gauge and needle, so someone somewhere has to define where the needle graphic should go and how far it should rotate. Or have I misunderstood what you're saying...?
