Delphi OpenGL engine

I need help creating a simple Delphi-based OpenGL engine. The requirements are:

- The basic principle is that it should be possible to add objects to the scene, and then render the scene as a output image.

- At the moment the only objects I need to add is 32-bit images. The alpha-channel of the images should be used.

- The parameters for each objects should be possible to change before each rendered frame.

- Parameters that I need to be able to set for each object are position (X, Y, Z), rotation (X, Y, Z), opacity (0-100 percent), scale (X, Y, Z).

- It must also be possible at anytime to change the image (with an image with a identical size) without re-creating the object.

- It should also be possible to change camera settings before rendering. At least position (X, Y, Z) and lens angle should be possible to set.

- As manipulation of images are the main thing, there are some things that is important: Images should be handled so that when all paramaters are at default values the image is rendered pixel-by-pixel to the target bitmap. Ie, a image of 100x100 pixels will still be 100x100 pixels when rendered. Unless there is any light added the image should appear identical to the input on the output.

- The ouput render should result in a 32 bitmap image of desired size (up to 1920x1080). It should be the result of all objects with the current properties, and with their alpha channels correctly combined. Render should not be done to screen, only to the image.

- Render should be done on the computers OpenGL graphic card, for fast render of complex scenes.

- Speed is the main focus - all actions has to be optimized for short execution time.

- It should be 100% delphi code, well commented and easy to modify and add functionality to.

- Values for position, scale and rotation should have a meaningful range, where the default is 0 (position and rotation) or 1 (scale).

Here are a pseduo code of how the engine should be used:

A: Init Scene

InitScene();

AddImage(AImage, ObjectID); // AImage = 32bit bitmap

AddImage(AImage, ObjectID); // AImage = 32bit bitmap

B: Render Loop

UpdateImage(ObjectID, NewImage); // New image = 32bit Bitmap

SetImagePosition(ObjectID, XPos, YPos, ZPos);

SetImageScale(ObjectID, XScale, YScale, ZScale);

SetImageOpacity(ObjectID, Opacity);

SetImageRotation(ObjectID, XRotate, YRotate, ZRotate);

SetCameraPosition(XPos, YPos, ZPos);

SetCameraAngle(Angle);

RenderFrame(TargetImage); // TargetImage = 32bit Bitmap

Please provide information on your experience with OpenGL and Delphi with your bid.

Note! Based on some experience from bids placed on previous projects here, I would like to add some

information about my self and my company: I am a developer myself, with more than 10 years of delphi experience.

I use this web site either to get help with specific problems, or when I simply dont have the time to complete the task myself.

In both cases I am looking for experts, who can provide me with the knowledge I might be missing. You should have detailed expertise in the ares covered by the project, and not spend paid time to learn new techniques.

All bids will be evaluated based on this background. So please read the project specifications carefully, and make sure you include any important information in the bid.

Thanks!
