Functions
gtcDBBuf*	gtc_new_buf (void)
	Create a new buffer to send GL commands to.
void	gtc_buf_delete (gtcDBBuf *buf)
	Destroy a buffer.
gtcDB*	gtc_pack_buf (gtcDBBuf *foo)
	After filling the buffer, send this DB to the client.
void	gtc_exec_db (gtcDB *db, gtcBufferSwapper *bs, int fast_flag)
	On the client, call this to execute the GL commands.
int	gtc_load_matrix (gtcDBBuf *buf, gtcReal m[4][4])
	Same as glLoadMatrix. Returns index for gtcDB, you probably don't need it.
int	gtc_perspective (gtcDBBuf *buf, gtcReal fovy, gtcReal aspect, gtcReal zNear, gtcReal zFar)
	Same as gluPerspective. Returns index for gtcDB, you probably don't need it.
int	gtc_ortho (gtcDBBuf *buf, gtcReal left, gtcReal right, gtcReal bottom, gtcReal top, gtcReal zNear, gtcReal zFar)
	Same as gluOrtho. Returns index for gtcDB, you probably don't need it.
int	gtc_swapbuffers (gtcDBBuf *buf)
	Same as glXSwapBuffers. Returns index for gtcDB, you probably don't need it.
int	gtc_light (gtcDBBuf *buf, int light, int pname, gtcReal param)
	Like glLightf. light is GTC_LIGHTi where i is between 0 and 7.
int	gtc_lightv (gtcDBBuf *buf, int light, int pname, gtcReal params[])
	Like glLightfv.
int	gtc_vertices (gtcDBBuf *buf, int n, gtcReal V[][3])
	as glVertexPointer. Returns index for gtcDB, you probably don't need it.

	as glNormalPointer. Returns index for gtcDB, you probably don't need it.
int	gtc_tex_coords (gtcDBBuf *buf, int n, gtcReal T[][2])
	as glTexCoordPointer. Returns index for gtcDB, you probably don't need it.

Detailed Description

API for sending commands to the client through a gtcDB.

To talk to a client, you create a database containing all the commands it needs to run. These will typically be a bunch of OpenGL calls.

Typedef Documentation

typedef struct _gtcBufferSwapper gtcBufferSwapper

a closure for swapbuffers. When you call gtc_exec_db(), some of the commands could be swapbuffers. In that case, on X a glXSwapBuffers call needs to be made, with the appropriate display pointer. On other OS's (eg, win32), the call and parameters are different. To keep gtc as OS agnostic as possible, this is a callback that will be used whenever GTC wants to swap the buffers.
