- this exposed a bizarre issue on Mac where dragging in <AGL/agl.h> in extensions.hxx was pulling in all of Carbon to the global namespace - very scary. As a result, I now need to explicitly include CoreFoundation in fg_init.cxx. - change SG_USING_STD(x) to using std::x Issues: - the logic for X11 and Win32 in RenderTexture and extensions is tortured, please see if you agree I got all the ifdefs correct.

/*
|
|
* Tiled Rendering library
|
|
* Version 1.1
|
|
* Copyright (C) Brian Paul
|
|
*
|
|
*
|
|
* This library allows one to render arbitrarily large images with OpenGL.
|
|
* The basic idea is to break the image into tiles which are rendered one
|
|
* at a time. The tiles are assembled together to form the final, large
|
|
* image. Tiles and images can be of any size.
|
|
*
|
|
* Basic usage:
|
|
*
|
|
* 1. Allocate a tile rendering context:
|
|
* TRcontext t = trNew();
|
|
*
|
|
* 2. Specify the final image buffer and tile size:
|
|
* GLubyte image[W][H][4]
|
|
* trImageSize(t, W, H);
|
|
* trImageBuffer(t, GL_RGBA, GL_UNSIGNED_BYTE, (GLubyte *) image);
|
|
*
|
|
* 3. Setup your projection:
|
|
* trFrustum(t, left, right, bottom top, near, far);
|
|
* or
|
|
* trOrtho(t, left, right, bottom top, near, far);
|
|
* or
|
|
* trPerspective(t, fovy, aspect, near, far);
|
|
*
|
|
* 4. Render the tiles:
|
|
* do {
|
|
* trBeginTile(t);
|
|
* DrawMyScene();
|
|
* } while (trEndTile(t));
|
|
*
|
|
* You provide the DrawMyScene() function which calls glClear() and
|
|
* draws all your stuff.
|
|
*
|
|
* 5. The image array is now complete. Display it, write it to a file, etc.
|
|
*
|
|
* 6. Delete the tile rendering context when finished:
|
|
* trDelete(t);
|
|
*
