Hi

Been using your GUI for my game, and it's been working great.

But i have a problem right now, i was wondering if it was possible to draw 3D elements inside the windows/controls, i've overriden the draw event, and was trying to draw a quad, but i keep getting an error when i'm drawing it: "A valid vertex buffer (and a valid index buffer if you are using indexed primitives) must be set on the device before any draw operations may be performed." So is this even possible, or am i just doing something wrong.

The quad isn't using vertex buffers or index buffers, it's just a normal DrawUserIndexedPrimtives call

_graphics.DrawUserIndexedPrimitives
<VertexPositionNormalTexture>(
PrimitiveType.TriangleList,
QuadtoDraw.verts, 0, 4,
QuadtoDraw.Indexes, 0, 2);

I have done this and it works best if you use a RenderTarget and then draw just the texture to the window. I can provide sample code if you like. It can be a little tricky getting the correct setup on the RenderTarget and DepthStencilBuffer.

Well if you were using a render target then Neoforce only updates at the target frame rate, which defaults at 60 fps.

Here is a video of my test program.

I don't have this exact code available right now (I am modifiying it for a physics app) but it's really quite simple I will try an write up another example by this weekend and post it up for you.

It basically just creates a RenderTarget and DepthStencilBuffer, renders whatever you want to it and then sets the resulting texture to an ImageBox. Some things to note is that you must call Invalidate() for the ImageBox or the ClientArea of the window. Also Neoforce sets up it's own RenderTargets not ready for 3D rendering that's why I created my own. You can render directly to a Neoforce window but you must make sure ALL of the graphics device settings are correct to include creating and setting a DepthStencilBuffer.

Hi

Sorry for the late reply, been quite buys :) But thanks to your example i got my code working nicely now :) thanks alot :)
